Is a Car Refrigerator Practical?

[EliasMarie]

Car refrigerators are very useful in summer. Here is the relevant introduction to car refrigerators: 1. Principle: Car refrigerators are an extension of household refrigerators, which can use semiconductor electronic refrigeration technology or compressor refrigeration. Generally, they have low noise and little pollution. While driving, you only need to plug the power plug into the cigarette lighter socket to cool the refrigerator. 2. Origin: The first type is an earlier product, and calling it a refrigerator may not be very appropriate because it does not have a refrigeration function, only a heat preservation function. When using it, you must freeze the items to be refrigerated in the refrigerator and then put them in the insulation box, with ice packs added if available. This way, the items can remain frozen for a short time. The advantage of this refrigerator is that it does not consume electricity and is relatively inexpensive. The disadvantage is that it cannot maintain temperature for a long time and has limited space.
