We bought the aluminum cooler for our driving tour through Sweden in the summer and not always we found overnight an electrical outlet. So the box was only while driving electricity and the night was mostly off. But at the beginning of the trip I have given into six one-cooled accus and it took a long time before they were no longer really cold. It was a better solution than without icebox. We had no fear rotten food. And other things that needed a good cooling, we have only bought when we were doing, they also consume the same. Large bottles fit naturally purely just lying. On something you can adjust but certainly. Otherwise, it does what it should.
