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.
Just wanted to say Great job. Your superior service and attention to detail has landed you a customer for life. I had recently made an identical purchase elsewhere online and was completely dissatisfied. Having no previous internet shopping experience, I assumed purchasing a household name brand from store "a" and store "b" there would be little difference. I will be the first to confess, I was truly mistaken. Still waiting to see a refund from the other guys. RJ Ingham — , USA —
