The best of both worlds, the two compartments in this fridge have separate temperature control settings allowing one to act as a freezer and one as a fridge. The size of the unit in particular is useful to campers, the 12v power adapter can be plugged into a cigarette lighter type 12v socket, and it can also be run off mains power via a 3 pin plug adaptor. The Auto cut off feature means that the fridge will cut out before it flattens your battery too far, this is especially important if you don’t have a leisure battery and are relying on your car battery via the cigarette lighter socket. After all no-one wants to be stuck in a field with a flat battery, unable to start their car!
