There are pins for battery ground and battery power (12V). Depending on the car, it might be tied to the ignition, or it might not.

- jcdavis 12y agoyea, I'm just surprised they have enough current to power a projector + arm cpu + fan.
- mikeash 12y agoMy car's 12V system warns me to limit use to 120W. That's for the "cigarette lighter" ports, but the OBDII power pin is probably similar if not on the same circuit. That'll run a lot of crap.
