Even the recommended 5V3A supply for the Pi4 is non-standard and requires you to either buy the official power brick or wade through a sea of sketchy Chinese knockoffs that may or may not deliver their rated power. I don’t understand why they haven’t explored alternative connectors or slapped a voltage regulator on the board in order to use a 12V supply. 5V5A USB is just ridiculous. USB only makes sense when you’re using universal requirements, but this might as well be a barrel connector as you can’t use any normal USB charger with it.

But it does support usb pd, starting with pi 5, you can use any usb pd power source, so long as it can provide the needed wattage
