Raspberry Pi uses USB-C and USB-C is more generous with power. Almost everything except computers provides 15W. With USB-C, devices request want they and there is no reason has to work with minimum possible.
The problem with the Pi5 is that they use weird profile, 5A/5V, that requires special charger. Most 5V chargers are 100W and beefy. If they hadn't cheaped out on power circuits, they could have used normal 30W charger. They should come out with new version that fixes that.
That’s crazy, 5A/5V is not and has never been in range of the USB power delivery spec. It only goes to 5 amps at 20V for the 100W output, or higher voltages in the newer Extended Power Range topping out at 5A/48V.
5A/5V what are they smoking?
Probably the same stuff they smoked when they cheaped out on a resistor on the raspberry pi 4 and made it so chargers thought it was an audio device.
Keep in mind at least 2A of that is to power the four USB ports at their rated 500mA. So if you don't have four USB devices loading the USB ports at their max, you should be fine with 3A.
