Would that work? I don't think the cig lighter in the Roadster is connected to the 12V battery. Although it works when the car is powered off so maybe so. Would be interesting to hear Tesla's view of that.This is partially why I carry a Port-a-Jump. (little battery, about 4"x2" that can jumpstart a car via the cig lighter.) (also to jumpstart friends.)
