Makeup Fridge Portable Home Electric Cooler & Warmer Box, Mini Refrigerator 7.5L car cooling&warming refrigerators

Principle: Unlike ordinary household refrigerators refrigerated by compressors, car-mounted refrigerators rely on electronic chips for refrigeration, using special semiconductor materials to form PN junctions to form thermocouple pairs and produce the Peltier effect, which is a new type of refrigeration method through direct current refrigeration The temperature range is 7 to 60 degrees. It can be used for both cooling and heating, the minimum cooling is about 7 degrees, and the maximum heating is 60 degrees (the specific temperature varies depending on the ambient temperature). Advantages and disadvantages: no need for refrigerant refrigeration (both compression type and absorption type are required), environmental protection and pollution-free, small size, low cost, no vibration, noise, and long life when working. The disadvantage is that the refrigeration temperature is affected by the ambient temperature, and the refrigeration cannot reach below zero, which is only suitable for preservation and heat preservation. Scope of application: suitable for fresh-keeping storage and heat preservation of beverages, food, fruits, and milk. Usage: It takes 2-3 hours to freeze unfrozen food and beverages. The small car refrigerator is not designed to freeze food, but to keep it warm. If used correctly as directed, food can be kept warm for several hours.
