Is powering it via the ODB port a wise thing to do? What sort of power does a dashcam draw?
The power draw is very little. The problem is that I don't drive a lot, so if I power the dashcam from the cigarette lighter socket, I have to remember to remove the power connector otherwise it will drain the battery. Plugged into the OBD port, I can leave it plugged in because it will detect when the voltage drops and switch off.
