The 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: The car refrigerator will automatically power off after reaching the battery protection setting value to protect the car from starting normally;
3. E-mark (electromagnetic interference): When the electronic control module of the car refrigerator works, it does not interfere with the electromagnetic interference of other electronic products in the car, and it will not affect the normal use of the car battery;
4. Anti-falling protection: When the car refrigerator is used, a slight tilt will not affect the normal operation. When the tilt reaches 45° or more, it will automatically stop working to protect the compressor;
