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 you guys are great. I've been ordering from you for years and never have problems. I've had some terrible experiences shopping online and some I am still dealing with.
Like I said - you guys are great - you have a customer for life. Dillon — Greenville, SC —
