What if I also want to use an old Macbook Air / Pro with a USB-C port? At this time, I asked for this USB-C 2 Magsafe adapter cable.
The appearance of the cable is very simple. One is a USB-C interface and the other end is a Magsafe interface. The principle is that a decoy chip is added inside, which is equivalent to letting the USB-C charger recognized the cable as a 60W laptop. After connecting the Macbook, you can see that it is a 60W power source in MacOS.
Compatibility tests are good. Macbook Air / Pro can use this cable for charging. After all, Air is originally equipped with 45W, 13-inch Pro is 60W, they all should be no problem. The 15-inch Macbook Pro is originally equipped with 87W power, but after connecting this 60W adapter cable, it can also be charged with 60W, but the speed is slightly reduced.
What we need to pay attention is that the corresponding USB-C charger needs to support 60W output. For details, please refer to the labels of various manufacturers. Here the use of Fastport DUO 60W by Inviolabs is perfectly charged. Both Air and Pro can provide maximum compatibility. At the same time, because this charger provides both USB-C and USB-A interfaces, one charger can solve the needs of all devices when going out.
The trick is to have a USB-C PD charger(above 60W) and a USB-C to magsafe cable. That's what Inviolabs' vision, fast charging and saving your precious time.

Samsung, Huawei, Google, OnePlus are now even Apple iPhone 11 Pro. Come with a fast chargers is an increasingly common practice, at least for high-end devices. But what we need to care when using a fast charger?
Battery life has become a top issue for mobile phone users. As we are using our phones over a longer period of time, battery life becomes more and more important throughout the day, which has become one of the key features that ordinary buyers look for after screen size. According to Kantar's Worldpanel ComTech Q3 2019 study, battery life is even more important than a good camera.
Now the mobile phone can be fast charged, we have a question: What effect does a large-capacity charger have on the battery of the phone, and over time, will fast charging possibly reduce the phone's power storage capacity? We also wondered what else we would do when charging, and whether this would cause unnecessary shorten life with the battery.
In short term, the mobile phone battery will not make big progress.
All mobile phones even most personal electronics and electric vehicles are using lithium-ion (Li-ion) rechargeable batteries. Making longer life batteries is a tough slogan, because battery technology hasn't changed for decades. Most of the latest advances in battery life now come from energy-saving features built into devices and software that makes charging and discharging more efficient.(Such as Tesla)
Another factor affecting our phones is the battery capacity. Compared to electric vehicle batteries, the power of a phone is very small. For example, the battery capacity of Tesla Model 3 is more than 4000 times than iPhone 11 Pro Max.
The output of a conventional charger is 5 to 10 watts. Faster chargers can increase it up to eight times. For example, the iPhone 11 Pro and Pro Max come with 18-watt fast chargers, and the Galaxy Note 10 and Note 10 Plus come with a 25-watt charger in the box. Samsung will sell you a super high-speed 45-watt charger for $ 50.
Unless the battery or chargers are technically defective, using a fast charger will not cause any damage to the phone's battery.
Let me explain why. The fast-charging process is divided into two phases. The first stage applies an impulse voltage to an empty or near-empty battery. This way you can increase from 50% to 70% in the first 10, 15 or 30 minutes. This is because during the first stage of charging, the battery can quickly absorb the charge without having a significant adverse effect on its long-term health.
For example, Samsung promises that its 45-watt charger can charge from zero to 70% in half an hour. Apple says the fast charger that comes with the iPhone 11 Pro can reach a 50% charge rate in 30 minutes.
Inviolabs had tested the Samsung Note10+ charging speed. Click here for the details. Also there is the testing for Samsung S10+: Three fast charging protocols, Samsung S10+ charging test
Do you know how much time it takes to charge the last 20% or 30% of the battery? The last part is the second charging stage, and phone manufacturers must slow down and carefully manage the charging speed, otherwise the charging process may actually damage the battery.
From iPhone 11 charging test, we can easily found that how the Apple charging management system works. Click here for the testing details.
Also, for the iPhone 8/X/XS Max all support fast charging, click here for the details.
The battery management system closely monitors the two charging phases and reduces the charging speed in the second phase to allow the battery time to charge full and avoid problems, which is why it can take up to 10 minutes to get the last few percentage points.
Overcharging once caused anxiety among users. They worried about that constantly plugging in the phone may charge the battery beyond its capacity, making the battery unstable, which may reduce the overall battery life or accumulate excessive internal heat and cause the battery to explode or catch fire.
However, according to the modern cell phone design, the battery management system cuts off the charge before the battery reaches 100% which could overcharges.
Unless there is a problem with the battery circuit, you cannot overcharge modern mobile phones. They have built-in protections that can completely prevent this. occur.
If you often keep your iPhone powered on during the day or while sleeping, you can turn on the iOS 13 battery setting called "Optimize Battery Charging", which will monitor your charging schedule and keep your iPhone's battery charge at 80— 90% . After that, it will recharge to 100% before you regularly unplug your phone. This is most suitable for people with conventional charging methods.
You may want to occasionally allow your phone to fully discharge to help the battery recalibrate its charge status. But this is not a problem for modern mobile phone batteries.
In fact, completely discharging the battery will cause a chemical reaction, which will shorten the life of the battery over time. In order to avoid full discharge, the battery management system includes a safety function. When the battery reaches a safety level higher than the empty battery, the phone will lose power. You only think you have reached zero when you see the last low battery warning.
If you want to maintain the health of your battery more aggressively, plug in your phone when the battery level drops by about 30% (well above the extremely low-stress battery level).
Heat is the real enemy of batteries. High temperatures can reduce battery life.
You should avoid exposing your phone to the sun, away from the window, and away from the dashboard of your car to prevent the phone from overheating, which will cause the battery efficiency to decrease over time. In extreme cases, an overheated battery may explode.
Does it mean you need to store your phone in a freezer? No. But try to avoid high temperatures. If you have been in the sun for a long time, try putting a towel or T-shirt on it, or putting it in a bag with a jug. The purpose is to prevent the internal temperature of the phone from rising.
Unless you use a fake or damaged charger and cable, mixing and matching cables and chargers will not damage your battery. However, you may not be able to charge as fast as using the device that came with your device.
Some phones (such as those of Huawei and OnePlus) use a proprietary charging design-the charger has built-in circuits that are responsible for fast charging. To take full advantage of your device's proprietary fast charging capabilities, you need a compatible charger.
Other phone manufacturers, such as Samsung and Apple, are more compliant with industry-standard fast charging rules and allow you to use a variety of compatible cables and chargers for fast charging.
The safest option is to charge your iPhone with Apple certified MFI products, because when using the non-MFI cables with the iPhone, the device may default to the lowest charging speed. Inviolabs provide the MFI USB-C to Lightning cables, with our Inviolabs FastPort series charger, you can charge your iPhone/iPad on full speed.
For Samsung and other USB-C PD supported cell phones, Inviolabs also provides the high quality USB-C to C cables. With our Dual port Fast Chargers, you can easily charge all your devices with just one charger.

Tips: How to save the battery life of my phone?
To extend battery life, you can use common energy-saving tips to save battery power, such as dimming the brightness of the display, turning off Wi-Fi and Bluetooth when not in use, and limiting background data usage by setting and focusing on applications that use GPS.
But the truth is, no matter how careful we are, our cell phone batteries can only last that long. The trick is to get as much time from the battery as possible without worrying about charging the battery all the time. That's what Inviolabs' vision, fast charging and saving your precious time.
]]>In addition to the 5W USB-A to Lightning cable, the PD chargers requires an MFi-certified USB-C to Lightning cable.
First is the traditional 5W charging test. The process of charging the iPhone 11 Pro is very stable. After all, the maximum power is only 5W, and the charging voltage is only 5V. The mobile phone handshaking 5W charging at the moment of connection to the charger, which lasts until 2 hours and 45 minutes, and then enters the constant voltage phase, and the power is continuously reduced. At 3 hours and 37 minutes, the power dropped below 0.1W, it become completely full.
Use 5W to charge iPhone 11 Pro, it can only charge 17% in half an hour, and 33% in one hour, fully charged in 3 hours and 37 minutes. The charging speed is very slow.
Next is the 18W PD fast charge kit that comes with the iPhone 11 Pro. Before iPhone shake hands PD fast charge, it must wait until it boot. After the cable is connected, the phone charges in Apple 2.4A mode, until 1 minute 48 seconds, the phone automatically turns on, the charging voltage rises to 9V, handshake PD fast charge, power Immediately climbed to around 18W and lasted for 29 minutes. After 31 minutes, the charging power began to gradually decrease, and entered the constant voltage phase at 1 hour and 12 minutes. The power continued to decrease until dropped to below 0.1W at 2 hours and 09 minutes, and the iPhone 11 Pro was fully charged.
The iPhone 11 Pro comes standard with 18W PD fast charger, which is much faster. It can charge 48% in half an hour, 81% in one hour, and only 2 hours and 9 minutes to fully charge.
The iPhone 11 Pro can charge more than 22W in low battery conditions. Is it faster to charge the phone with a higher power PD charger than the original charger? Next testing with the 30W PD charger. After connecting the cable, you also need to wait for the phone to boot. When the phone is powered on for 3 minutes and 21 seconds, the PD protocol is used for fast charging, and the charging power starts to rise slowly from 18.7W. After 22 minutes, the power began to gradually decrease. It reached the constant voltage stage at 1 hour and 8 minutes, the power continued to decrease until the power dropped to below 0.1 W at 2 hours and 7 minutes, and the mobile phone was completely charged.
The 30W PD charger will be faster, charging 53% for half an hour, 84% for one hour, and 2 hours and 7 minutes for full charge.
Finally, we compare the three sets of data of this test together.
From reslut the charging efficiency of the first one hour using the PD fast charging is extremely high, and it can be charged to about 80%. Compared with the 18W PD fast charge, the 30W PD fast charge is only 2 minutes away from the 0-100% charge. The 30W PD fast charge speed is mainly faster in the early stage. 30W charger is 5% more than the 18W in the first half hour.
iPhone 11 Pro fast charging power up to 22W+, using the advantages of 30W charger in the first half hour can provide more than 5% of the charge than 18W, it is useful if you can only charge the phone for a few minutes. (Click to Tweet this)
The whole charging speed is not much different. Inviolabs recommend the iPhone 11 series users, who only charge the phone, keep using the built-in 18W PD charger. For the users with a variety of devices, who want to charge the iPhone with 22W of optimal power can purchase a 30W PD charger. In addition to better charge the iPhone 11 Pro, it can also be used for iPads, Switch, Macbook Air etc.
So in order to achieve fast charging, we need a charger that can support fast charging. As mentioned above, iPhone and iPad only support the PD fast charge protocol, but not other protocols such as Qualcomm's QC, so we need to be clear that charging devices need to support the PD protocol.
Next, is the consideration of max power out. For the iPhone, according to the test, the 18W charging speed has met daily needs, considering daily portability and compatibility. Inviolabs recommends using an 18W dual port charger. Provide dual PD and QC interface, full compatibility.
For iPad or macbook devices, it supports charging power of more than 30W. Inviolabs recommends a 60W dual port charging device. Dual port high power input.
Finally, we need to choose a cable. What we need here is a USB-C to Lightning cable, which is usually referred to as CtoL. Apple only support the USB-C to Lightning cable for fast charge. Be aware the this cable has Apple's MFi certification.
Inviolabs offers the following options: DurableLine and DurableLine Plus series. If you using the cables travelling, Inviolabs recommend to use the Plus series. We have prepared a storage bag for you. The nylon braided thread brings better durability. We also recommend you have 2 other DurableLine cables, one in the office another at home.

Although the video is all in Chinese, we can still clearly understand the whole process through the subtitle function of Youtube.
At the beginning of the video, he use iPhone 6s and 6s plus as an example. The motherboard design of the two is basically the same, so you can modify the 6s motherboard into the 6sp body and use its screen. But starting from iPhone 7, the motherboard design is different, the memory capacity is not the same, so there is no way to mod.
The latest iPhone 11 pro and pro MAX are back to the same motherboard design with same memory. Maybe it is good for Apple to save the cost.
The only difference is that the 11 pro motherboard has one more resistor than MAX, which should be the type identification.
Install the 11 pro's motherboard into the pro MAX body and screen directly, it can't be powered on.
After manually replacing the resistor, the 11 pro's motherboard + max body & display is powered on and into system. As the info showed, although the model still shows 11 pro, all operations are the same as pro MAX.
"Since iPhone 11 pro and pro MAX have almost the same motherboard design, it is possible to turn iPhone 11 Pro to a Pro MAX.
By handwork." ( Click to Tweet This)
The detailed operation as following, this man's handwork is really good, pure manual operation。 If there is a little mistake, two new iPhones would be trashed. Inviolabs strongly recommends that you not to do this at home.
]]>It is very easy for Apple to standardize the phone with the 18W PD charger. Is it really unnecessary to give the iPhone 11 a quick charger? What is the benefit will the iPhone 11 user buy a PD charger at her own expense? Today, Inviolabs will answer if this is necessary.
At the beginning, it is sure that the iPhone 11 supports the USB PD fast charging function, and the maximum power is as high as 22W+ for the two Pro models. Since it supports PD fast charge, let's do the PD fast charger and a 5W charger comparison now.
In this testing, there are three groups, which are: the iPhone 11 comes with the 5W charger, the iPhone 11 Pro comes with the 18W PD charger, and the Apple 30W PD charger.
First is the charging process of the 5W charger. From record, it is charging at 5.05V/0.97A, 4.9W.
The charging process of the iPhone 11 is very stable. It is connected to the charger for a handshake of 5W, which lasts for 2 hours and 44 minutes, and then enters the constant voltage phase, and the power continues to decrease. It dropped to below 0.1W until 3 hours and 45 minutes, till it fully charged.
5W charger which comes with iPhone 11 can only charge 16% in half an hour. And only charge 32% in one hour. It takes 3 hours and 45 minutes to fully fill. It is too slow.
It is not surprised that the iPhone 11's 5W charging speed is so slow, nearly 4 hours. Fortunately the phone supports USB PD fast charge, let us put on the iPhone 11 Pro standard 18W PD fast charge kit for testing.Now that the phone is charging at 9.02V/1.95A and 17.62W.
After the 18W charger on, the battery is charged at 7.5W. After the phone is automatically turned on for 53 seconds, the PD is quickly charged and the power immediately climbs to about 17.5W. It began to gradually decrease until 23 minutes, and entered the constant voltage phase at 1 hour and 8 minutes. The power continued to decrease until the power dropped below 0.1W at 2 hours and 16 minutes till the iPhone 11 was fully charged.
The 18W PD speed is hugely increased, charging 53% for half an hour, 80% for one hour, and only 2 hours and 16 minutes for full charge.
As we mentioned earlier, the iPhone 11's PD fast charge power can be up to 22W. Is it faster to charge the phone with a higher power PD charger? Let's test with the Apple 30W PD charger. Now the phone is charging at 8.91V/2.53A, 22.59W.
Charging with a 30W PD charger is very similar to 18W, and the peak power is increased to about 22W. After the charger is on, the battery is charged with 7.5W power until the phone is automatically on until 3 minutes and 21 seconds. After the power is turned on, the PD protocol is fast-charged. At this time, the charging power reaches 20W or more, and slowly rises. At 17 minutes, the maximum power of this charge is 21.6W, and then the power begins to gradually decrease. When it enters the constant voltage phase at 1 hour and 5 minutes, the power is continuously reduced. Until 2 hours and 16 minutes, the power drops below 0.1W, and the mobile phone is fully charged.
30W PD fast charging and the 18W PD fast charging is almost the same, charging 55% in half an hour, charging 84% in one hour, and fully charging 2 hours and 16 minutes.
Finally, we compare the three sets of data of this test together.
From the comparison curve, it clearly that the PD fast charger speed is much higher than that of 5W original charger, more than 50% in 30 minutes, charging more than 80% in one hour, using original 5W charger takes half an hour to charge 16%, and it reaches 32% in an hour. Using the PD fast charger for iPhone 11 is one-and-a-half-hour shorter than 5W.
Compared with the 30W and the 18W, they have a difference of 2 minutes. And they almost using the same time to fully charged. The difference is small, 30W is still faster than 18W, although it is only a little.
"If you are going to use/using the iPhone 11, throw away the original 5W charger.
A faster USB PD charger is needed." (Click to Tweet this)
1, iPhone 11 original comes standard with 5W charger is very slow, it is very necessary to purchase PD charger and MFi USB-C to Lightning cable at your own expense.
2, iPhone 11 using PD fast charge, measured in half an hour can be charged with more than 50% of the power, killing 5W charger of 16% for half an hour.
3, iPhone 11/iPhone 11 pro can fast charge power up to 22W +, 30W PD charger and 18W PD charger, the speed gap is about a few percentage points, the pursuit of cost-effective users can purchase 18W PD charger. Users with higher demand can increase their budget to purchase 30W PD charger. In addition to better service for iPhone 11, it can also be used for iPad, thin and light notebooks, etc.
So in order to achieve fast charging, we need a charger that can support fast charging. As mentioned above, iPhone and iPad only support the PD fast charge protocol, but not other protocols such as Qualcomm's QC, so we need to be clear that charging devices need to support the PD protocol.
Next, is the consideration of max power out. For the iPhone, according to the test, the 18W charging speed has met daily needs, considering daily portability and compatibility. Inviolabs recommends using an 18W dual port charger. Provide dual PD and QC interface, full compatibility.
For iPad or macbook devices, it supports charging power of more than 30W. Inviolabs recommends a 60W dual port charging device. Dual port high power input.
Finally, we need to choose a cable. What we need here is a USB-C to Lightning cable, which is usually referred to as CtoL. Apple only support the USB-C to Lightning cable for fast charge. Be aware the this cable has Apple's MFi certification.
Inviolabs offers the following options: DurableLine and DurableLine Plus series. If you using the cables travelling, Inviolabs recommend to use the Plus series. We have prepared a storage bag for you. The nylon braided thread brings better durability. We also recommend you have 2 other DurableLine cables, one in the office another at home.

Also, you can check with Inviolabs' blog about PD charger testing for the iPad Air3/Mini 5 here. The iPad Air 3 can reach the 30W when using the right PD charger.

In this section, Inviolabs will focus on the PD protocol and give you some advice on purchasing an iPhone.
Looking back at the iPhone's practice of fast charging, it actually started in the iPhone 8 series, and the iPhone 8 supports PD 18W fast charging. The full name of the PD is USB Power Delivery, which is the USB charging standard and technology released by the USB Developers Forum (USB-IF) in 2012.
In recent years, USB-IF is pushing the PD protocol as the charging standard for all devices. At present, some of Apple's mobile devices, such as iPhone, iPad, and MacBook, have joined the PD protocol, and Android phones are also compatible with the PD protocol. So the PD protocol is expected to be the only standard for mobile devices and desktop devices.
If you want to find a charger for your mobile device that can fully implement fast charging, consider supporting the PD protocol.
After 7 years of development, the PD protocol has reached the PD 3.0 version. In version 3.0, PD supports PPS (Programmable Power Supply, PPS). PPS is compatible with other fast-charge protocols already available in the market. In PD 3.0, the latest QC 4.0 fast charge has been supported. The charging rules for PD 3.0 are shown in the figure below.
At present, there are two types of fast charging schemes: a high voltage and a small current scheme and a low voltage and a large current. For example, we often hear the Qualcomm QC fast charge protocol, which uses a 9V/2A high voltage and low current solution. Qualcomm's use of this solution was limited by the maximum current supported by the charging line at the time, when the maximum current supported by the Micro USB charging line was only 2A.
Therefore, you can only choose high voltage and small current for fast charging. This charging method is very friendly to the user without replacing the existing interface and charging cable. However, since the voltage is increased, the heat generation of the charger is quite serious.
The second option is low voltage and high current. For example, the VOOC flash charging introduced by OPPO was the low voltage and high current solution used. This solution solves the problem of heat well, but the requirements for wire are very high. OPPO has specially customized the relevant wire to realize VOOC flash charging.
The PPS in the PD is compatible with both high voltage and low current and low voltage and high current. This is a unique advantage of the PD protocol.
After learning about the PD protocol, I believe that you have a clear understanding of the future of the PD protocol and would like to try it out. Because the PD's fast-charged charging head can really reduce the number of chargers that can be carried when traveling. So how do you choose the right fast charging device for yourself?
If you only want to charge your iPhone,you need an Apple MFI certified USB-C to Lightening charging cable, and a PD-based charging head, at least 18W, so that you can achieve fast charging.
If you use iPhone and MacBook air, it is recommended to use a USB-C charging head that supports PD. If it is another mobile phone that supports the QC protocol, it is recommended to use the Charger of 60W dual port, A+C version.
If you have too many electronic devices and don't know how to choose the right fast charge product, please leave a comment and I will recommend the right solution for you.
Inviolabs also has done a test for iPhone 11 PD Chagers in order to find out which is better, you can click here to for the details.

Apple is using 7nm transistors (like on the A12 Bionic), and there are now 8.5 billion transistors — that’s a huge update compared to the A12 Bionic, which had 6.9 billion transistors. The A13 Bionic still has four high-efficiency cores and two high-performance cores.
The new Apple models detected by Antutu are iPhone 12, 1, iPhone 12, 3, iPhone 12, 5. They correspond to iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, Antutu v7, the scores are 456655, 455452, 462098, which are almost the same. Compared with the previous generation A12, the best score has increased by as much as 33%!
The iPhone 11/Pro/Pro Max all come with 4GB memory, which is consistent with the results o GeekBench.

Nintendo listed the new Nintendo Switch as offering 2-2.5 more hours of play time. It is the only change in specs they listed when comparing the new and original Switch.
]]>
Inviolabs found that the first thing is the charger, now only the original Samsung charger can be selected, which worth 50 dollars. Third-party charging devices are currently not available because Note+ require 45W+ with the PPS. PPS (Programmable Power Supply) programmable power supply, a type of Power Supply supported by USB PD3.0, is a power supply that can realize voltage and current regulation using USB PD protocol output. The PPS specification integrates current high-voltage low-current, low-voltage and high-current charging modes. In addition, the PPS specification reduces the voltage regulation range to 20mV, which is one-tenth of the QC3.0 standard, and the voltage regulation is more precise.
Note10+ and S10 5G have the same 25W PD3.0 (nominal 9V 2.77A), the measured maximum is about 18W, with good compatibility, just the previous PD charger with PPS function, it can reach 18W speed. The 45W charger is 10V 4.5A, so it needs to support the PPS protocol and the 10V4.5A charger to support it. Currently only Samsung original can be realized on the market. At the same time, because the current exceeds 3A, according to the USB-IF regulations, the charging cable also needs to be equipped with an emarker chip to be compatible.
So, what is the emarker chip cable?
Summary: If you use Note10's 25W charger, the charging cable only needs C to C interface, but if you want 45W fast charging, you need not only Samsung original charger, but also need the 5A C2C cable when purchased which is less choice on the market. Referring to the previous 25W and 45W charging tests, the difference is not very obvious, perhaps this is why Samsung does not have a 45W charging head.
]]>
Recently, a charging test on the Note 10+ had been done. From the actual test, the difference is not big. Although compared to 45W charging, 25W charging takes 8 minutes to fully charge 100% of the power, which is much smaller than expected.
25W charger output:
The Note 10+ comes standard with a 25W charger that the phone power on and screen off takes about 1 hour and 5 minutes to 100%. With the 45W charger, it takes about 57 minutes to fully charge the phone when the phone is turned off. After testing, Note 10+ with 45W charger, the full charge time advantage is only 8 minutes.
Although the full charge is not obvious, the difference is still obvious in the 30 minutes before charging. 25W fills 67% in 30 minutes, while 45W fills 73% in 30 minutes.
Overall, Note 10+'s SuperFast fast charge is somewhat "indigestion", and it's really fast in the early stage of charging, but the speed of full charge is not much different. With this one experiment, will you spend $50 on Samsung to buy a 45W SuperFast fast charge? And if choosing the third party charger, the USB PD PPS function is need. Inviolabs recommed to using the 30W PD with PPS fast charger.
You have probably already used USB connections to charge smaller devices either from your computer or from an outlet. That works well because past USB connections had enough wattage to successfully power up those smaller batteries. However, prior versions of USB could handle a limited amount of power, which is why laptop chargers have typically retained their larger, bulkier cables.
USB-C is a universal charging standard. That means that, technically, it doesn’t matter what USB-C charger you use, it should be able to power up a laptop with a USB-C charging port and power bank.
In the real world, this is taking a while to come true. Today the majority of laptop USB-C chargers are interchangeable, but it’s not guaranteed.
Some laptops come with USB-C ports that don’t charge. This is most common on laptops that come with their own, proprietary charger — although a number of laptops can be charged either way, only the propriety charger tends to power up a laptop more quickly. The Samsung Notebook 9 is an example of that, as is the 2019 HP Envy 13. If you’re not sure exactly how to charge your laptop, check the manufacturer’s website, or look up a review of the system here at Digital Trends.
Laptops that rely entirely on USB-C, meanwhile, might not charge with just any charger. PCWorld, in its testing, found that HP’s Spectre x2 wouldn’t charge with any USB-C charger besides its own. HP said that that was intentional because a bad charger could damage the device, or cause it to malfunction. Other devices, like the Apple MacBook Pro, don’t have such tight restrictions — a new USB-C authentication system could help with this issue in the near future.
While we haven’t personally heard of any damage from using a USB-C charger other than the one that came with your laptop, there’s always a slim risk when plugging a laptop into an unknown power source. Faulty cables can also be a problem. In short, it’s a good idea to buy cables and chargers from reputable sources and think twice about using that cable you found laying on the ground in a conference room.
You can buy additional USB-C cables for your own security.
You will also want to watch your USB-C power mode, which you can find in your laptop settings, usually in the power/battery section. Here, you may find that you can switch Type-C’s output, choosing whether to receive power or send power. If your USB-C laptop charger isn’t working when by all rights it should be, check your settings to make sure it is set to receive power.
The right adapters and USB-C-to-other-port cables can make all sorts of magic happen — here’s a list of what you can do on MacBooks alone. But when it comes to charging your laptop, stick with the simplest configuration possible. The other adapters are useful for transferring data in older drives or supporting HDMI, etc., but don’t have a place when it comes to charging. Also, keep in mind that not all USB-C ports can charge. The laptop must be configured for charging via Type-C for this process to work.
Two additional notes are worth mentioning.
First, there’s a variant of USB-C that’s a lot more powerful — Thunderbolt 3. Choose a laptop with at least one Thunderbolt 3-enabled USB-C port and you can connect multiple 4K monitors at 60Hz and greatly increase your laptop’s gaming performance via an external GPU enclosure. Second, there’s a brand-new version of USB on its way that will be even faster and provide even more standardization. Dubbed USB4, we can expect laptops with the new ports to start arriving in 2020 or so.
]]>As we know, Google launched Google Pixel 3, Pixel 3 XL, Pixel Slate and Google Home Hub in New York on October 9.
Pixel 3/3 XL is based on Qualcomm snapdragon 845 platform, which has 4GB of running memory and provides 64GB/128GB storage version. The hardware doesn't look bright, but its optimized camera algorithm makes Pixel 3/3 XL a regular in DxOMark's top five. DxOMark commented that “Google Pixel 3 camera review: The best Pixel yet”. Their camera has a rear 12.2 megapixel single shot, F/1.8 aperture, and a front 8 megapixel "wide Angle + ultra wide Angle" dual shot. It's super wide Angle lens can provide up to 97 ° Angle of view for many people to take selfies. In addition to the usual HDR Plus mode, Pixel 3 XL improves the photo experience by adding more AI features to the camera. Besides taking photos, AI is undoubtedly the most eye-catching part of this mobile phone. At the Google I/O conference, Android Pie drew attention to AI assistants with its powerful assistant, and this time Google has brought this technology to Pixel 3 XL.
As the charging performance that we care a lot today, Google Pixel 3 XL has a mediocre charging speed actually. It has a 3430mAh battery, and supports up to 18W fast charging.
From the configuration, Inviolabs suggest that one 18W PD charger and usb c2c cable is needed for the Google Pixel 3 XL.
]]>The next iPhone(iPhone 11) seems to continue to adopt the Lightning connector, but the charging cable has been changed to the USB-C to Lightning cable, and it seems that the attached power adapter may also be changed to the Apple 18W USB-C power adapter is. Inviolabs found the report from the Japanese blog Mac Otakara.
The inclusion would represent an upgrade to the currently shipping 5W USB adapter. The 18W adapter allows fast charging with iPhone X charging from 1 percent to 79 percent in one hour.

Since it is the flagship, the performance is cool. Take S10+ as an example. It is equipped with Qualcomm Snapdragon 855 processor, the highest 12G+1T storage combination, built-in 4100mAh battery capacity, and supports fast charging technology.
As fast charging technology on mobile phones, Samsung is also an early batch in the industry. As early as the Note 4 mobile phone, it is equipped with its own AFC fast charge. Although it was early, the Samsung has always been "low-key" in charging, especially after the "Note 7 event.”
Up to now, the “Note 7 Incident” has been ushered in the “10th Generation” S10 series in the past three years. Will their power be improved? Inviolabs found an S10+ mobile phone, and today and we will bring you a charging evaluation.
Samsung S10
Samsung S10+ standard 15W AFC fast charge charger
Protocol testing of the S10+ original charger, it support for AFC fast charge and DCP protocol.
The Apple (A1695) charger, 18W power, support PD fast charge protocol, charge Samsung S10+, voltage 9.02V, current 1.42A, power 12.9W, turn on PD fast charge.
Samsung (EP-TA200) charger, power 15W, support AFC fast charge, charge Samsung S10+, voltage 9.03V, current 1.62A, power 14.69W, turn on AFC fast charge.
QC 3.0 Charger 24W,voltage 9.17V,current 1.62A,power 14.88W,QC fast charging on。
S10+ full charge charge changes. As can be seen from the above figure, the three different fast-charge chargers charge almost the same when charging the Samsung S10+.
Half an hour: Samsung S10+ original charger is charged 38%, Apple 18W PD charger is charged 39%, and 24W QC charger is charged 40%.
One hour: Samsung S10+ original charger is charged 75%, Apple 18W PD charger is charged 77%, and 24W QC charger is charged 78%.
The whole process takes time: Samsung S10+ original charger 1 hour 59 minutes, Apple 18W PD charger 1 hour 58 minutes, 24W QC charger 1 hour 57 minutes.
The Anwer is no. The high temperatures may damage the battery. For the details: The truths about cell phone battery life: fast charging, overheating
As the charging performance, Samsung S10+ adopts USB-C interface and supports three fast charging protocols of PD, QC and AFC. It has wide compatibility and is very convenient when selecting charging accessories. After the full charge test, it was found that the Samsung S10+ is charged by the PD charger or by the QC and AFC chargers. Its maximum power is about 15W, and the whole process takes nearly two hours.

As USB Type-C has the highest data transmission speed of 10Gbps, and its maximum power transmission speed can reach 100W, therefore this interface is widely used by more and more devices.
With the rapid popularity of USB PD fast charging on mobile devices such as laptops and mobile phones, we have found that many USB PD chargers that support high current output are equipped with one USB-C with E-Marker to USB-C cable. The E-Marker is a chip which inside the USB-C to C cable, it record the cable's speed and highest current.
Generally speaking, we can classify the E-maker cables by the application, one kind is by charging, and the other one is by data transmission.
In general, charging-based USB-C cables are USB2.0, in terms of feedbacks from the market; the USB PD-charged standard cables in the market are all USB 2.0. Under the standard of USB2.0, charging cable can be divided into two types: 60W (20V/3A) and 100W (20V/5A).
According to the standard of the USB-IF Association, cables with a transmission current below 3A or below 3A are not required to have E-Marker chip inside; only when the current exceeds 3A, the cable must be equipped with a E-Marker chip. At present, many USB PD charging power in the market does not reach more than 60W, so the standard parameter is not equipping with E-marker chip in order to save costs.

E-Marker info for ThinkPad power supply cable
It is learned from the standard of the USB-IF Association, the E-marker chip is not required for the cable, when the transmission speed of the USB-C cable is USB 2.0. However, when the transmission speed reaches USB 3.1 Gen1 (5Gbps) or USB 3.1 Gen2 (10Gbps), the E-Marker chip must be used, which has nothing to do with the power of USB-C cables. However, the E-Marker chip not only marks the data performance of the cable, but also marks the power transmission capability of the cable.
E-Maker info for 60W USB 3.1 Gen2
Finally, it is easy to distinguish these USB-C cables with E-Marker by users in daily life. The maximum charging power of cable without E-Marker chip can only reach 60W, and the maximum data transmission speed can only reach the level of USB 2.0 (480Mbps). Regarding the cables with E-Marker chips, you can learn about the specific performance of the product through E-Marker information.
The advantages of using the USB-C interface are clear, first of all, faster data transfer speed, the new iPad Pro supports USB3.1 gen2 10G data transfer, and also supports USB PD fast charging. Apple comes standard with an 18W USB-C PD charger for the iPad Pro. Can this charger feed the appetite of the new iPad Pro? Inviolabs made this testing for you!
With the new iPad Pro 11-inch as the test machine, the Apple A1410 12W (APPLE2.4A protocol) charger, the standard A1695 18W (USB-C PD) charger, and the A1947 61W (USB-C PD) used in the notebook were selected. The charger is used for comparison to see who can feed the new iPad Pro.
First came the USB 12A USB-A interface. This charger is the standard charger for the old iPad Pro. It has the APPLE2.4A charging protocol. The new iPad Pro does not support the APPLE2.4A protocol? ! Not even support! not support!
Since the APPLE2.4A protocol is not supported, the Apple 12W charger has a poor charge of 5.14V / 1.41A / 7.26W for the new iPad Pro.
Next, it is the turn of the 18W USB-C PD charger that comes standard with the new iPad Pro. You can see that the Apple 18W charger is near full load with a power of 9.0V / 1.91A / 17.26W.
Finally comes the 61W USB-C PD charger on the MacBook Pro: 15.06V / 2.33A / 35.16W, the charger can finally feed the new iPad Pro.
Since the new iPad Pro does not support Apple 2.4A, it takes 5V/1.5A DCP protocol when charging with old iPad pro charger, and the 7.25W power is maintained for 4 hours. 39 minutes, almost a straight line, then slowly falling, very traditional CCCV charging algorithm.
The new iPad Pro is charged with the 18W USB-C PD charger that comes standard with the new iPad Pro. The power is between 17W and 18W. The platform lasts for 1 hour and 42 minutes. After that, the charging power is slowly reduced. It is also a very traditional CCCV charging algorithm. .
Using the 61W USB-C PD charger that comes standard with the MacBook Pro to charge the new iPad Pro is another charging algorithm with a peak power of over 30W and a power platform between 27W and 30W.
Three chargers are drawn into a 0%~100% power percentage table. First look at the half hour charge level comparison: 12W charger is charged 9% for half an hour, 18W charger is charged for 22% for half an hour, 61W charge The device charges 33% of the charge for half an hour.
Look at the time-consuming comparison: using the iPad 12W USB PD charger takes 5 hours and 32 minutes, which takes the longest time; using the standard 18W USB PD charger takes 2 hours and 53 minutes; using Apple's 61W USB PD The charger can be fully charged in 2 hours and 35 minutes, nearly 20 minutes faster than 18W;
Summary:
1. After the new iPad Pro is switched to the USB-C interface, it supports USB PD fast charging;
2, the new iPad Pro does not support the Apple2.4A charging protocol, the charger using the USB-A interface even with the APPLE2.4A protocol, can only charge 7.5W (DCP) power;
3, the new iPad Pro maximum charging power up to 35W / 15V / 2.33A, power platform 27W ~ 30W;
4, the new iPad Pro fastest charging speed takes 2 hours and 35 minutes, considering the large battery of the new iPad Pro, this charging speed is still quite fast.
So in order to achieve fast charging, we need a charger that can support fast charging. As mentioned above, iPhone and iPad only support the PD fast charge protocol, but not other protocols such as Qualcomm's QC, so we need to be clear that charging devices need to support the PD protocol.
Next, is the consideration of max power out. For the iPhone, according to the test, the 18W charging speed has met daily needs, considering daily portability and compatibility. Inviolabs recommends using an 18W dual port charger. Provide dual PD and QC interface, full compatibility.
For iPad or macbook devices, it supports charging power of more than 30W. Inviolabs recommends a 60W dual port charging device. Dual port high power input.
Finally, we need to choose a cable. What we need here is a USB-C to USB-C cable.
Inviolabs offers the following options: DurableLine and DurableLine Plus series. If you using the cables travelling, Inviolabs recommend to use the Plus series. We have prepared a storage bag for you. The nylon braided thread brings better durability. We also recommend you have 2 other DurableLine cables, one in the office another at home.
If the new iPad Pro uses the old iPAD Pro 12W charger or other USB-A charger, the speed will be slow until you suspect it is failed; the 18W USB-C PD charger for the new iPad Pro "is not impossible to use", but Unable to feed the new iPad Pro, the fastest charging speed is not achieved. To feed him, you need a USB-C charger with 30W or more, with a voltage range of 15V2A~15V3A, so you can get the fastest charging experience. (Click to Tweet)

If you would like to have a look on iPad Air 3(2019) and iPad mini 5 charging test, Inviolabs also done the testing here. Click for the details.
The Anwer is no. The high temperatures may damage the battery. For the details: The truths about cell phone battery life: fast charging, overheating
Both the iPad mini 5 and the iPad Air 3 use the powerful Apple A12 processor. In addition to the powerful configuration, the charging has also been enhanced. Both products support USB PD fast charging.
However, Apple is as unsatisfactory as ever. It only provide 10W charger and USB A2L cable. The whole charging process is like a Mercedes-Benz with a bicycle engine. Inviolabs recommended that every iPad Air 3/Mini 5 user replace the original 10W charger when have it.
The iPad Air3 has a battery of 30.2 Wh, and iPad mini5 got 19.1Wh, both charging method uses Apple's exclusive Lightning interface. It does not use the popular USB-C interface. Do they support USB PD fast charging? Let’s check it out.Make use of iPad Air 3/Mini 5 to automatically shut down, then charge it with the Apple 61W (A1947) PD charger, and the Power-Z KM001 for the data recording:
In the beginning, it turned on the Apple 2.4A charging mode. In less than 1 minute, it was converted to USB PD fast charging. When charging for 48 seconds, its power reached 30.5W; then the power dropped back and Gradually rising, reaching 30.06W in about 44 minutes; then the power gradually decreased, after several large fluctuations, the charging was completed at 2 hours and 36 minutes, and the power dropped to 0.07W.
In terms of power consumption, the battery capacity of the iPad Air3 is 30.2Wh, the charge is charged to 36% for half an hour, and it is charged to 68% for one hour. As the battery saturation becomes higher and higher, the power is greatly reduced, and the subsequent battery capacity is increased. The speed also began to slow down, eventually taking 2 hours and 36 minutes.
When power 0% , it handshaking the 5V Apple 2.4A charging mode. After less than 1 minute, it automatically switches to USB PD fast charging. After 52 seconds of charging, its power reached 18.83W; then the power dropped back and gradually increased to 19.4W in about 38 minutes; then the power gradually decreased, after 2 times and 34 minutes after several large fluctuations. Charging, the power drops to 0.07W. In addition, the maximum power of the whole process is 20.88W.
In terms of power consumption, the battery capacity of the iPad mini5 is 19.1Wh, and the charge is charged to 36% for half an hour. When it is charged to 67% for 1 hour, as the battery saturation becomes higher and higher, the power gradually decreases, and the subsequent battery capacity increases. It also began to slow down and eventually took 2 hours and 34 minutes.
The iPad Air3/mini 5 is equipped with a powerful A12 processor, which is excellent enough. However, it does not adopt the popular and compatible USB-C interface, but continues to adopt the Lightning interface. Fortunately, it supports PD fast charge, but it should be noted that you want to use it to fast charge you must use the MFi-certified USB-C to Lightning cable.
"For the choice of charger and cable, iPad Air 3/Mini 5 charging power up to 30W/20W, the original 5V/2A 10W charger is obviously not enough, a 30W PD charger and a MFi-certified USB-C to Lightning cable is the basic requirement."(Click to Tweet it)

The APPLE 2.4A charging protocol was first applied to the iPad, and the maximum charging power can reach 5V/2.4A 12W. However, this charging protocol is not the first application on the iPhone XS Max, but from the iPhone 6S and later supports this protocol, the charging power of the mobile phone can not be stabilized at 12W for a long time, and the charging power of each model will also be some differences.
With the USB PD charger for 29 minutes, the phone's power reaches 50%, and it can reach 78% in one hour; it takes only 2 hours and 17 minutes to fully charge. In the case of the standard 5W charger, only 16% of the battery can be charged in half an hour, and the mobile phone can only reach 33% in one hour; it takes 3 hours and 42 minutes to fully charge.
For the iPhone XS Max, using the USB PD fast charge saves about 90 minutes of charging time compared to the standard charger. But the most important thing is that USB PD fast charging has a more obvious speed advantage when the mobile phone has low battery and needs emergency charging. (The speed is 3 times that of the standard 5W charger within 30 minutes. It is awesome), this is the charm of USB PD fast charging.
So in order to achieve fast charging, we need a charger that can support fast charging. As mentioned above, iPhone and iPad only support the PD fast charge protocol, but not other protocols such as Qualcomm's QC, so we need to be clear that charging devices need to support the PD protocol.
