too powerful? what do you mean? USB PD by default supplies 5v the same as USB A and increments from there
5v is pretty low - 3v is pretty common logic voltage, but i doubt anyone would use voltage that low for battery charging?
do you mean you don’t like to “waste” a perfectly good powerful USB C port? you can get some pretty low watt USB C plugs, but honestly i much prefer to just have a brick with 7 big ports
right… i think that’s less of a problem with PD chargers and more of a problem with non-compliant A chargers (and the device itself being non-compliant): wattage/amperage at these has nothing to do with the protocol (other than auto shutoff under a given current draw, but that’s not instantaneous)
i believe that the USB spec says there needs to be a resistor bridging one of the pins to receive power? i can see USB-A chargers just dumping 5v through the cable no matter what and USB-PD more reliably implementing the spec because it’s more complex, so less reason to cut corners
