why are there no chargers that let you set how much current/power they deliver
like sometimes i want to charge my devices as fast as possible because i'm in a hurry, but most of the time i'm fine with a slow charge that takes multiple hours but is easier on the battery
actually why don't the devices themselves allow you to do that? why can't i tell them to draw whatever they need to power the hardware, plus x mA to charge the battery?
