Review on Efficient Battery Saver: Koolatron F70110 12V in Sleek Black Design by Leroy Stanton

I'm traveling with a purchased Koolatron cooler, which I also don't recommend. The energy saving mode does not work. It plugs in and works until the car is turned off, and shortly after it is turned off, the energy saving indicator will change color from green to red and turn off the cooler. I would say 5-10 minutes after parking the car. I don't understand buying this product or colder products as they only work when the engine is running. What if you have to stop? Also, it takes quite a while for the cooler to reach a safe temperature for storing food. So you literally have to run it before you put your food in it and never turn off the machine. it makes no sense. DO NOT BUY!
