To test how much faster I can charge a smartphone, I used the Xiaomi 11i HyperCharge— a phone that takes only 20 minutes to charge fully and comes with a 120W charger in its box. While it uses Xiaomi’s proprietary charging technology to refill the battery in less than 20 minutes, it also supports non-proprietary chargers with USB-PD at a maximum charging rate of 68W. GaN-based semiconductors require much smaller space to deliver the same power as silicon. This is why a standard silicon chip can be replaced with a GaN chip that is much smaller in size. As a result, GaN chargers are relatively smaller than standard chargers while being more efficient and delivering more power.

As seen during his review, the difference between a 25W Samsung charger and one rated for 45W is only marginal. In my testing, charging with the Ugreen charger displays “super fast charging” on the phone, while using any other charger shows only “fast charging.” in-1 Wireless Charging Station: Supports multiple fast charge protocols and Qi 15W wireless charging for 4 devices at full speed. Therefore, for applications with higher voltages and long duration, while silicon tends to offset a lot of heat — leading to wasted energy, GaN is an ideal replacement. GaN is also a better conductor of electricity than silicon at high voltage, which means electric current passes faster through it. These properties make GaN more desirable for chargers. Tushar Mehta/Digital Trends Anyone invested in the Apple ecosystem will have had to confront the need for multiple USB-C ports when they're home and away, with iPhones, iPads, and Macs all vying for the connectivity these days. But in many cases, there's still a lingering need for USB-A to charge older devices, and that's where Ugreen's 4-in-1 100W GaN X Fast Charger comes in handy.Lenovo is one of the best laptop brands you can buy from at the moment. While the Lenovo 14w Gen 2 AMD certainly isn't pushing the boundaries with performance speeds, it's functional. It has an AMD 3015e processor along with 4GB of memory so it's pretty slow but will at least run Windows 11 Pro. We are, however, pleased to see that there's 128GB of SSD storage. Many laptops in this price range use eMMC storage which is much slower so it's good to see something a little speedier here. I have two MacBook Pros. One is a newer design with an M1 chip and better cooling. The other is a 2019 Intel that has cooling problems. Unfortunately, the 2019 one is a work machine that I use more heavily.

The Galaxy S22 Ultra went from 18% to 60% in 30 minutes and took nearly 70 minutes to complete charging. Even though the Galaxy S22 Ultra supports fast charging at 45W, the charging speed does not appear dazzling, especially when we look at brands such as OnePlus and Xiaomi that already sell phones with much faster charging. If you are looking for slightly more power output while also being able to charge four devices at once, you can consider the Spigen 120W GaN charger on Ugreen claims that this means it can charge an iPhone 13 to 60% in 30 minutes or fully charge a 16-inch MacBook Pro in 1.5 hours, and thanks to the latest GaN chipset, it's three times faster than Apple's standard iPhone charger. Those claims stood up to scrutiny in my tests, although the big caveat here of course is that they only apply when one device is plugged into the charger and in the relevant port for its power requirements.

Now that we have a fair understanding of a GaN charger’s advantages, let us focus on the 100W GaN charger from Ugreen. The Ugreen charger has a solid construction. Although the outer shell is made of plastic, it feels exceptionally sturdy. Tushar Mehta/Digital Trends and those are relatively more affordable than the Ugreen charger. But we cannot recommend them without testing them ourselves. How long with it last?

But despite all its benefits, GaN has one major tradeoff: The manufacturing cost tied to the complex process required to rectify its crystal defects. Therefore, the applications of GaN are limited to accessories such as chargers and have not been applied to the production of smartphones and PCs. Build quality The problem is when you have 3 USBCs plugged.. the picture graph displayed by Ugreen is correct all the power distribution is correct here's the ISSUE. the moment you plug in the THIRD USBC EVEN IF YOUR NOT CHARGING ANYTHING ON THAT THIRD USBC - The charger itself adjusts power as if you were. what happens is you now go down to 65W but your only charging ONE item so if im charging my macbook air on Port 1 and port 2 and Port 3 aren't plugged into anything it will only do 65W so if I plug say my Ipad Pro into Port 2 instead of doing 65w/35w it does 45w/30W because I have 3 USBC cables plugged Lastly, you cannot fast charge phones from brands like OnePlus or Oppo that offer superfast but proprietary charging.
