Main differences:

1. Anti-vibration and anti-shake: The car refrigerator has good anti-vibration performance and is suitable for use on bumpy roads;

2. Battery protection: After the car refrigerator reaches the battery protection set value, it will automatically power off to protect the car from starting normally;

3. E-mark (electromagnetic interference): The electronic control module of the car refrigerator does not interfere with the electromagnetic interference of other electronic products in the car when it is working, and it will not affect the normal use of the car battery;

4. Anti-fall protection: When the car refrigerator is in use, a slight tilt will not affect the normal work. When the tilt reaches more than 45°, it will automatically stop working to protect the compressor;
