Yeah power seems like such a small thing but for an SBC it's a pretty big deal.
The power usage is also pretty crushing for it the Pi's usage in hobby Robotics. Finally we have some computing power but now it's unusable because how are you going to get 5V5A from a powerbank? We could power the Pi4 from a decent USB C supporting powerbank, But this is no longer the case for the Pi5.
If they supported "normal" USB PD then at least a powerbank with quick-charge support (9v3a) would work and give you the same total 25W wattage. And the PD USB chargers would have been way cheaper because 9v3A get mass produced. This 5V5A is some Apple tier of "propriatary" standard and I really wonder why they did it.
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
I refuse to admit 5v5a is USB PD. This is like USB3.1gen2by4 Rev 9001
USB PD was meant for
15w = 5v3a
30w = 9v3a
45w =15v3a
60-100w = 20v3-5a
Phones that wanted to do it different made up their own name with blackjack and WOOX charging. I don't need the Pi foundation single handedly screwing this up.
