@Jo works with some stuff

shorting the data lines on the device side will tell the device that it's a charging-only USB cable instead of a data cable, if the device thinks it's a data cable it'll obey the spec and only sip 500mA, if it's a charge cable it'll pull more current

Or at least that's how it used to be, I have no idea what things are like now with quickcharge and usb c and all that stuff
