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.
Ordered the Skyworth 15.6 tv over the weekend, it was processed on Monday and I had it on Wednesday. Good product, Great Service. Would order through 12volt-Travel again... Thomas K.
