At MWC 2022, Oppo demonstrated its 240W GaN charger that can charge a 4,500mAh battery to 100% in under 10 minutes.

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.

The 100W power is divided among the ports when you connect two devices. The power output of the topmost port is reduced to 65W, whereas the second port is limited to 30W. The power output of the remaining two ports remains unchanged. Meanwhile, when you engage all three USB Type-C ports, the maximum output of the topmost port is further restricted to only 45W. Lastly, when all four ports are being used, the power output of all the ports from top to bottom is 45W, 30W, 10.5W, and 10.5W, respectively.

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. 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.

We also boast an active community focused on purchasing decisions and technical aspects of the iPhone, iPod, iPad, and Mac platforms. But Samsung is the probable culprit here, as Andy Boxall, senior mobile writer at Digital Trends, noted in his review of the Galaxy S22 Ultra. 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.” Complete Safety & Reliability: Dynamic Temperature Sensors and intelligent PMW chip ensure safe charging.Pro Display XDR, LG 32UL950-W 4K UHD LED Monitor, Dell UltraSharp 32 USB C 4K Monitor, BenQ DesignVue PD3220U, ASUS Designo, etc. The Ugreen 100W GaN Fast Charger is an excellent charger, especially if you have a lot of gadgets and want to charge them all at once. Not only does it save space because it can charge four devices at once, but it also enables fast charging, and it only requires one wall outlet. It's also easy to carry on the bag with its foldable plug, and it can replace all of your other chargers. 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 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. Other than that, both models are functionally identical and feature a built-in "Power-X" power delivery system that can intelligently adjust the power output to protect a device's battery. Essentially, the power distribution system allows the charger to adjust the power provided to each port based on what's plugged in. The top two ports are capable of delivering a maximum of 100W, while the third is capable of up to 22.5W, and the bottom USB-A port offers 22.5W.
