The compressor car refrigerator is similar to a household refrigerator, as both rely on compressor-driven cooling. It cools quickly and powerfully, reaching temperatures as low as -20°C, making it capable of ice-making and food preservation. Available in various sizes, it features segmented temperature control and is durable, making it the mainstream direction for future car refrigerator development. The compressor car refrigerator can be used in vehicles or at home with a power converter, serving as an extension and supplement to household refrigerators. Its key feature is portability, making it ideal for self-driving trips.
