When plugged into your car or truck 12 volt outlet
cigarette lighter accessory plug, the Koolatron 12V Battery Saver F70110 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. You'll never have to worry about your car starting again with the 12 V Battery Saver. Use with all Koolatron coolers so your car will start if you forget to disconnect the 12V plug.
