When plugged into your vehicle''s cigarette lighter, the Koolatron 12V Battery Guard senses when your vehicle voltage drops below 11 volts. The Battery Saver then shuts off the current to all accessories plugged in, preventing further drainage. It reconnects automatically when you start your vehicle.
