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.
I had to thank you because sometimes all you here are the complaints! I had to thank you for the excellent customer service. I had purchased a 12 volt TV/DVD and had not installed it right away and when I did, it did not work properly. It was over the 30 day warranty. I was concerned knowing that I had purchased it from an internet company. Not the issue here.. you replyed immediatly with a return authorization and within 2 days I had a new tv. WAY TO GO! I really appreciated it!
