Tips on Car Refrigerators:

Principle: Unlike ordinary household refrigerators that use compression cooling, vehicle refrigerators rely on electronic chips for cooling, utilizing special semiconductor materials.P-N junction, forming a thermocouple pair and generating the Peltier effect, which is a new type of cooling method using direct current for cooling. The temperature range is from 7 to 60 degrees. It can both cool and heat; cooling around 7 degrees, and heating up to 60 degrees (the specific temperature varies depending on the ambient environment).

Advantages and disadvantages: No needrefrigerantRefrigeration (both compression and absorption types), small size, low cost, no vibration or noise during operation. The downside is that the cooling temperature is affected by the ambient temperature, and the cooling cannot reach below zero degrees. It is only suitable for preservation and heat retention.

Scope of application: Suitable for the preservation and storage, as well as heat retention, of beverages, food, fruits, and milk.

UsageFreezing food and beverages that have not been frozen before takes 2–3 hours. The design of car mini-fridges is not for freezing, but for keeping items warm. If used correctly according to the instructions, the food can remain warm for several hours.
