Does the USB stay powered when the car is off? I want to plug in a small flash drive with music on it, but I don't want it to stay on when the car is off, on the off chance it drains the battery.

Mine always stays plugged in, three different cars, Kona, Santa Fe sport and a Soul. Never had a problem. Once we left them in the garage for a month while on vacation and they started up immediately.

USBs are memory sticks and they don't really draw power from the source they're plugged into.

True. I did verify however, that if you have your phone plugged into it, it will charge the phone even when the car is off.
