The Koolatron Battery Saver detects when your battery drops to 11-Volts and shuts off the current to all accessories plugged into it.
The battery saver prevents further battery drainage and reconnects automatically when you start your vehicle and begin re-charging your 12 volt battery.
The Koolatron 12 Volt Battery Saver will operate devices up to 5amps.
