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 have just completed my first 100% satisfactory online purchase. I have shopped online before and was about to give up on it all together. Giving the internet a shot at redemption, I set out to find a GPS with trucker routes.
I came across several websites before landing on 12volt-travel. A couple of the other sites didn't answer their phone, some that did were very rude and others I just couldn't understand. One I think was rude but really couldn't tell with the heavy accent.
The folks at 12volt-travel were very helpful, courteous, easy to understand and very quick to ship. I am loving my new GPS and my new relationship with 12volt-travel.com. Ronald B. — , CA — R&L Team Trucking
