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.
Hey, you guys are amazing. We were thinking we might have our order in time for our next trip to Yosemite. UPS arrived as we were packing up to hit the road. Wow, in time for this trip. Just figured I'd take time to say thank you before hitting the road. We wont be updating it just yet (trying to get out the door) but we do have a super cool new GPS to play with now. Seems a little large now that I'm holding it, thinking we should have done the 5inch but I'm gonna keep it. Bigger is normally better =0)
