Even still I wonder if they could have added USB-PD capabilities in order to use 9V or 15V to bring the current down. A 5V 5A USB supply is very unique (even the previous 5V 3A was niche) as standard USB supplies that we’re all used to typically max out at 2.5A. $12 for the official power supply is a decent price but you’re severely limited on options if you don’t have the official supply.

Looking at the power supply listing, it says that it is USB-PD. It lists output as “5A @ 5.1V, 3A @ 9V, 2.25A @ 12V, 1.8A @ 15V”.
I fully admit that I don’t understand USB-PD, though. Does the Pi have to support it too?
