Car refrigerator, as the name suggests, is a refrigerator designed for vehicle use. Its main characteristics include small size, light weight, low power consumption, and can adapt to the bumps and vibrations generated by the vehicle during driving. There are usually two types of car refrigerators:

1. ** Semiconductor car refrigerator ** : This type of car refrigerator uses semiconductor materials for refrigeration and does not require a compressor, so it has low noise and long life. However, its cooling capacity is relatively weak, and it is suitable for keeping food or drinks low temperature, rather than for cooling them down substantially.

2. ** Compressor refrigeration Car refrigerator ** : This type of car refrigerator uses compressor refrigeration, has a strong refrigeration capacity, can reduce the internal temperature to a very low, and even can be kept frozen in the hot summer. However, due to the need for compressor work, so this type of refrigerator is relatively more power consumption, noise is larger.

The car refrigerator is ideal for long trips, camping, picnics and other outdoor activities, and can easily carry and preserve food and drinks. When choosing a car refrigerator, you can decide which type of car refrigerator to buy according to your personal needs (such as refrigeration capacity, capacity size, power consumption, etc.).
