Looks very compact. "peak 60W, stable 40W" what length of time can it do 60W?

From the article:

> The thermistor monitors the internal temperature and dynamically adjusts the power level to reduce output power when the temperature rises.

My guess is that it's dependent on the ambient temperature, but that's just a guess! I can't imagine what the restriction on peak power would be other than temperature rise, though...

I have a generic slim GAN charger that does a similar stepdown, 65W -> 45W. Different form factor, but same 80g weight.

Peak power tends to last about 10 minutes or so.

I bet their telemetry shows that a lot of people grab a quick charge while in the shower or the like, and that 10mins is a good amount of time for that.

Or put another way, past ten mins it’s just as likely the phone will be plugged in for hours or overnight and the charge speed is irrelevant.

Also, it may be to avoid overheating the phone. Otherwise you might expect to see a GAN charger where the body is a heat sink.

That should be on the phone to increase its own resistance and slow down the power intake.

18 mins

I believe it’s around 15 minutes.
