Can car refrigerators be used for household purposes?

There are two situations, pure vehicle mounted and cannot be used directly. A transformer is needed to convert 220 AC to 12 or 24V DC, and the interface is like a cigarette lighter. This type of transformer is available online.
In addition, if it is dual-use, there will be a conversion switch and a transformer at the back of the refrigerator for you to use at home.
However, the refrigeration capacity of car refrigerators is limited, usually 18-20 degrees lower than the ambient temperature, with a heating energy of about 60 degrees and a minimum temperature of 5 degrees. They can only be used for refrigeration or insulation, and freezing is not recommended.
