I love that the battery is replaceable. Though I wish mobile devices included tiny backup batteries that give you ~1min to swap the battery without having to reboot the device. This would especially be useful for my gopro which I often use for long captures that I don't want to interrupt. But it would also be nice on my PinePhone.

They won't let you buy those batteries in non-US locations. The "suggested alternative" is to file down a Samsung battery.

As appalling as this is, I kind of love it. Pine stuff is for hackers 8-)

Those 65W Navitas based chargers are actually all exact copies of the reference design, and most are made by a single factory.

GaNFETs are there mostly for the marketing, and don't make any much more difference than few percents efficiency at such power level.

I'd have to look at the numbers, but a few percent points of efficiency can be a big difference in the power (and thus heat) dissipation of the device; going from 90% to 92% efficiency reduces the power dissipated in the device by 20%.
