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 received my Rechargeable 3/8 Drill that I ordered from you guys and I just wanted to say WOW. The drill is powerful and the ability to recharge it through the car cigarette lighter in the car or truck is perfect for when I am working at different places throughout the day. Tthe 21 piece tool set that came with the drill was in itself worth the price (it's like getting the drill for free). It really got me going with all I needed for the job.
