The best 65w gan charger

We found that some chargers, specifically all three chargers we tested, could not sustain their highest possible wattages and would shut down after less than 20 minutes. We conducted a second series of heat tests with each charger at one watt below its maximum rated wattage (ex: 59 watts on a 60-watt charger) and recorded the temperature there.

Unfortunately, silicon has reached the apex of its efficiency. This means silicon has effectively hit a dead end, which you can no longer improve. This is problematic in today’s world. Power efficiency requirements and environmental regulations quickly outdo silicon semiconductors, as they can no longer keep up with modern demands.

Our 65W GaN Charger is also relatively small; rather than the traditional square with folding prongs, it’s an extruded rectangle measuring 1.4 by 1.4 by 2 inches, with the port on the bottom and the prongs sticking out of the side. Even though the size is impressive and performed as well as our pick, we don’t think it’s worth the higher price, especially since it doesn’t come with a cable.

Though it is conservatively rated for 65 watts, in our tests, the charger managed a maximum sustained rate of 72.6 watts (19.2V / 3.78A). After 20 minutes of that maximum, the temperature hit a steamy 139 degrees Fahrenheit, but the charger was a much cooler 120 degrees.

Due to the difference in properties of the two materials, GaN-based semiconductors are more than twenty times faster than ordinary silicon-based chargers. Moreover, they can deliver the amount of power thrice and charging speed while being half the size and weight of their silicon counterparts.

Viewed from one side, it looks fine, plastic, but with smooth rounded corners and a small, hidden logo on the bottom; viewed from the other side, the entire surface is filled with tech specs and safety information. Of course, this being a desktop charger, you can turn it on its side. Sadly, this particular model is not currently available in the UK.
