A cooler with 2 cooling compartments keeps food and drinks separate and at the right temperature. That way, you can freeze meat on 1 side while cooling drinks on the other. This is useful when you're going on vacation or out for the day. Most models have separate parts with their own temperature. You can choose whether 1 side is freezing and 1 side is cooling, or that both parts are cooling. That way, you can use 1 cooler to cool and freeze at the same time.
