The Robot GaN charger has three USB ports: one USB-A port that can send up to 22.5W of power; two USB-C ports that can send 65W and 30W of power, respectively. It surprised me that the charger was able to balance the load so that it still got close to its stated outputs even though I had split the output between my laptop, my iPhone, and the power bank.
Even though the charge times had definitely gotten longer, the two USB-C ports still gave off a little more than half of the power that was expected. When a new device was plugged in, the charger would figure out the best way to charge that device instantly. One thing that it did well was always send most of the charge to my power bank that was connected to the 65W USB-C port.
The leftover charge was split evenly between my laptop and smartphone, with about 7W of power going to each. After I unplugged my laptop from the USB-C port that was sending 30W to my phone, it went from getting just over 15W to getting 30W. While GaN technology makes the process of converting energy more efficient, it does so without making the charger much heavier. When talking about the average customer, this means a charger that doesn’t get too hot. Some heat did get to the very small robot, but it wasn’t too hot to be dangerous.

Where to Get UGREEN RG 65W USB C Charger?
The 65-watt charger has three ports, two USB-C ports and one USB-A port. The 30W charger only has one 30-watt USB-C port. The USB-C1 port can handle up to 65 watts, but the USB-C2 port can only handle 30 watts. Finally, the USB-A port can send up to 22.5 watts of power. The 30-watt version should be enough to charge most phones in less than an hour if you only want to charge one thing at a time. The 65-watt Nexode RG, on the other hand, is what you need to power, say, a MacBook Air, an iPhone, and an iPad.
But the 65-watt charger won’t charge at its fastest speed if you use all three ports at the same time. These are the fastest speeds you can get when charging two things at the same time. The 30-watt Nexode RG charger was the first one we looked at. Our USB-C connection said that the M1 MacBook Air used 28 watts. Then we looked at our smart plug and saw that it was using 34.4 watts.
That means we were wasting about 7 watts of energy to heat, which is about 20% of the energy we used. Then we looked at how much power the 65-watt charger used. We used the same M1 MacBook Air this time, which drew 45 watts, along with a Vivo X90 Pro that was empty and a 6th-generation iPad that was empty. Each of these devices drew 7.5 watts.
