After all, the vehicle refrigerator is used to store food items, so it must be related to the size of the capacity. The larger the capacity, the more items can be stored. However, larger capacity means larger volume. Compared with the narrower space in the car, the capacity should still choose a car refrigerator that fits the car space. Such as compact models, it is recommended to choose  6L-20L size; off-road models are recommended to choose  20-40L capacity.

    At the same time, you should also choose according to your own needs for the use of the car refrigerator, such as whether the voltage of the car cigarette lighter matches the car refrigerator, whether the length of the power cord of the car refrigerator is sufficient, etc.; finally, it is recommended to choose the inverter car refrigerator, because the inverter compressor can Precisely controlling the speed of the compressor can precisely control the internal temperature, so as to save electricity and reduce noise.

    Furthermore, a good refrigerator must be able to freeze, but a car refrigerator that cannot freeze is obviously lacking in cooling performance. A car refrigerator that can make ice, that is to say, the minimum temperature can be below 0 degrees, and there are more items that can be stored in this temperature range. Whether it can freeze or not depends on the refrigeration method of the on-board refrigerator. At present, compressor refrigeration is also a relatively recognized refrigerator in the industry with a refrigeration temperature below 0 degrees.
