    i really wish school just had a day where they covered how a USB port works, showing how you can literally just cut all but the power cables to limit things to charging only

      That’s old dumb usb. USB c also needs a 5.1kohm resistor between cc1 and gnd (or data lines to negotiate fast charging but then its a whole thing)
