i want to turn on and off a usb device (heating pads, total 10w or less) automatically. i think something like 5min ON, and 20min OFF. i haven't tested the heating pads yet, so i don't know what timings would be comfortable.
it would be powered by a portable usb power bank (yet to be purchased). my hope is that it can be really low power, like less than 1 watt or even less than 0.5 watts. but if not, i would like to know what power consumption it will be.
i don't know how to make circuits, i might be able to wire usb ports to an input and output if needed, with instructions.
