My old honda fit had one of those inside the glovebox. I believe you were meant to plug in a flash drive or ipod and leave it forever. It did not provide enough power to actually charge a battery.
Oh. That's interesting. I have a 2018 Fit and I've never been able to get the USB port in the center console to charge anything. I bought it used, so I just assumed it was broken and moved on to using an adapter in the cigarette lighter. I wonder if that's what's actually going on?
Tesla does something similar as their USB port for flash drives is in the glovebox. It is intended to make the dashcam drive harder to steal.
