This is a great cheap simple little gadget. It's excellent also for using it with a laptop.

I tried it the other day when I got it. I didn't ignite the engine, I just powered on first, then plugged the device in, and it lit up.Dumb question - I thought the USB ports remain powered even when the car is off. So do you have to manually switch off your LED light strip?

I then purposely left it in and powered off and the light went off.
