I had a OwlCam backordered prior to buying my Bolt. I was on the fence about cancelling it, but I haven't and I do still want a dash cam in the car. It pulls power from the OBDII port under the dash and remains powered when the car is off for up to 24 hours and then it wakes on motion. Does anyone have an experience with how much power this will draw and how it will influence the number of miles per charge I am able to get out of the drive battery? Or will it just pull from the 12V battery? I'm not very technically knowledgeable about the distribution of power from the car battery and the drive battery.
