A portable camper car electronic refrigerator is a powered mobile cooling system, usually powered by the car's 12-volt electrical system, to keep food and beverages cold (or frozen) indefinitely. Large refrigerators mean more capacity, but with a higher current draw, they take up more space in your car. When choosing a refrigerator, measure the interior space to make sure it will fit, including any mounting hardware or extra height for the rails. Also, consider any vent clearance and make sure you have enough room to open the lid.

    Large refrigerators can also be heavy—a fully loaded refrigerator can make your car exceed its gross vehicle mass (GVM) if the whole family plus gear is already in the car.

    Dual-purpose refrigerators run on 12 volts or utility power, while 3-way refrigerators can run on electricity or gas. So which is better?

    Dual-purpose (compressor) portable refrigerator

    Dual-purpose refrigerators use the same compressor technology as home refrigerators, although they are designed to run on your car or truck's 12- or 24-volt battery as well as utility power. They're best for most applications because they're designed to shut down a car's electrical system without drawing too much current but can switch to 240 volts in a powered campground or home.

    Unlike gas refrigerators, compressor models imply regular battery recharging, so they might not be the best choice for a month on the spot, but they'll happily tick away with a small solar panel setup.

    Its advantages are as follows:

1. Good performance even in hot cars and high ambient temperatures.
2. Some can double as a freezer.
3. Work on uneven terrain or slopes.
4. Can be run from solar panels for off-vehicle use.
5. Specially designed for high efficiency, and low current consumption using car batteries.

    shortcoming:

1. Setting a consistent temperature when the ambient temperature changes can be tricky.
2. In quiet campsites, compressor noise may be noticeable.
3. The battery must be charged regularly, otherwise, your refrigerator will stop working.
4. If you run out of solar energy, it will shut down overnight.
5. The AC adapter may need to be purchased separately.
