we measured .2W, so plan for it to take years to drain the battery.Just got the new kit with the OBDII adapter. Seems to work great, but I don't see the unit ever shutting off -- the blue ring is lit up all day and night while the car sits. I understand there is a physical switch, but I doubt my wife's going to bother flipping it on and off. If the OBD II adapter is left on, is the empty mount going to drain my battery if I go on vacation for a week? I don't mind if it's a couple watts as it should generally be negligible, but not sure what the drain would be long-term.
