USB-C1/C2：5V/3A 9V/3A 12V/3A 15V/3A 20V/5A 100W MaxUSB-C3： 5V/3A 9V/2.5A 12V/1.88A 22.5W MaxUSB-A： 4.5V/5A 5V/4.5A 5V/3A 9V/2A 12V/1.5A 22.5W Max Ugreen includes a graphic (shown above) that explains the variable wattage of the different ports based on what's plugged in. For example, if you have two devices connected to the first two (100W) ports, the top port outputs 65W and the second port delivers just 30W. As you'd expect, the charger's power output gets divvied up further the more devices you connect. For instance, when all four ports are occupied, the first (100W) port tops out at 45W, so you have to consider what you're plugging in if you want to prioritize a particular device for fast charging at maximum wattage. For me Im not going to pull the port 3 plug out of the UGreen everytime I want max speeds I don't understand why just because you have 3 USBCs plugged in and if your charging 1 or 2 items does the charger itself distribute power as if it was charging (3) things, This only happens if you plug all the USBC ports. doesn't matter if your charging on them or not.
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.The external shell comes in a dark gray color and feels similar to a brushed aluminum surface in terms of feel. This gives the charger a premium appearance, and it could even succeed in fooling you that it is made of metal and not plastic. Overall, the charger feels robust, and while I would not recommend doing so consciously, it should be able to withstand some moderate falls. Supported charging standards GaN, or gallium nitride, is a more efficient semiconductor used as an alternative to silicon. The energy gap between the valence and the conducting bands on GaN is nearly triple compared to silicon, and this gives it much electric and thermal stability at high voltage and temperatures. Safe and Reliable: Equipped with intelligent protection against short circuits, overvoltage, overheating, and overcurrent. The top two out of the three USB Type-C ports on the charger support charging at 100W — when used individually — while the third one is limited to charging at only 22.5W. The bottom-most port, i.e., the USB Type-A port, is also limited to 22.5W. Although Ugreen endorses a 100W output from the charger, you must remember this only applies if you use the charger to charge just one device at a time. Charging speeds on each port Lastly, you cannot fast charge phones from brands like OnePlus or Oppo that offer superfast but proprietary charging. Availability
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 qualityDuring my testing, the Xiaomi 11i HyperCharge went from 10% to 100% in just 24 minutes when hooked to the GaN charger. This result is nothing but spectacular.
