Types of 12V Refrigerators

12V refrigerators are basically divided into three types. We took the liberty to discuss these to make you aware of the options available and the mechanisms of their working, so you know what you are investing in.

Thermoelectric Refrigerators

Thermoelectric refrigerators don’t exactly carry a compressor. Even though they may look like compressor refrigerators, their functioning is very different. The price point is something that shows a considerable difference as well since these refrigerators are much cheaper. These maintain their internal temperature based on the external environment’s temperature. This means that they cool to a temperature about 35 to 40 degrees lower than the external environment.

Compressor Refrigerator

Compressor refrigerators work on the same principle as your household fridge. They have a true compressor and have both compressor and freezing technology. These are the most expensive type of refrigerators, more than both absorption and thermoelectric, but for a good reason. These are the coldest refrigerators you will get your hands on. Furthermore, they are highly energy-efficient.

Absorption Refrigerators

Absorption refrigerators can run on a variety of power sources, be it AC, DC, or gas; however, they work best on gas. These are a portable option for you as they are particularly designed to be fit in your RV or boat. They aren’t exactly temperature controlled and not the best at cooling either, as they only cool to 30 degrees below the temperature outside. This translates to them not being the greatest option for you to travel with on long distance or at very high temperatures.

How We Choose These Models

These are all the factors we take into consideration before a product makes it to our best of lists. These major concerns are a product's overall performance and how it holds up long term, and are therefore important to consider.

That is something which you would want for your investment as well. All of the units we have talked about have great customer service for your assistance.


A 12V refrigerator is not the cheapest purchase, but in fact one of the most expensive ones you will make for your traveling, therefore, you would want a refrigerator that has a good and long warranty plan from a well-trusted brand.
