This freezer has a three-level battery protection function which not only guarantees normal operation of the freezer but also protects the battery of the vehicle.

  1. Set the freezer to its “on” state.
  2. Hold down the” O” button until the display flashes “H”.
  3. Press the” 0″ button again to select a low voltage protection level “L”, medium voltage protection level “M”, or high voltage protec­tion level “H”. The factory default is “H”.

Battery Protection

L / M / H

  • 8.5-10.9V /10.1-11.4V / 11.1-12.4V
  • Vehicle Battery / External Battery or Spare Battery


  • Due to the different output voltages of different vehicle power supplies, if the voltage protection appears (if the display reads “F1 “), you can lower the battery protection setting by one level (“H” adjusted to “M” or “L”).
  • We do not recommend that you run the freezer while the engine is off. If you must run the freezer while the engine is off, set the protection level to “H” (high). If the freezer runs for too long without the engine on, the vehicle may not be able to start.


The freezer is not working

  • Check if the power supply is faulty.
  • Check the plug to ensure it is in good contact.
  • Check if the cigarette lighter fuse has blown.

  • This is the normal sound of flowing refrigerant.

Excessive freezing inside the refrigerator

  • The temperature is set too low.
  • Confirm the door is closed and the seal is intact.
  • Make sure the inside of the freezer is dry before use.

Water droplets accumulate around the shell or door seal

When the moisture in the air meets the cold shell of the freezer, it condenses into water droplets. This condensation can be wiped off with a towel.

The compressor starts loudly

When the compressor initially starts, the motor will usually run at a high speed. This produces a loud noise, but it will decrease after the speed has stabilized.

Inaccurate temperature displayed

  • If items put inside are too hot, the internal temperature will be uneven while the temperature stabilizes.
  • Frequently opening and closing the freezer door causes varying airflow, resulting in an unstable internal temperature.
  • Make sure that the unit of your thermometer matches the unit of the freezer display.
