The decision to buy a 12V mobile car freezer always comes with another question: what size refrigerator do I need? While the answer may seem simple and/or limited to the size of your vehicle, the choice of a single compartment refrigerator or dual control unit does add complexity to the decision.

    On that note, let's first look at the pros and cons of single-compartment camping refrigerators versus dual controls.

    As the name suggests, a single-compartment refrigerator has just an inner box, a thermostat, and a temperature control panel. This means that you can use the unit as a dedicated refrigerator, or as a dedicated freezer - but it cannot serve both applications.

    The dual-control camping refrigerator has two internal storage compartments with a dividing wall between them. The unit also boasts two thermostats and two temperature control options. This setup greatly increases the versatility of a camping refrigerator, as it allows you to use one side of the unit as a refrigerator and the other as a freezer. Alternatively, you can set up the two interior bins as a combination refrigerator or combination freezer.

    You might be looking at both options and thinking, "Why would anyone want a single compartment refrigerator when dual control units offer the best of both worlds?

    Well, single-compartment refrigerators/freezers are generally more affordable than dual-control units, and they're generally more efficient as well.
