Battery power detection
The device features a multi-level battery guard that protects your vehicle battery from excessive discharge when the device is connected to the built-in DC power supply. If the cooler is operated with the vehicle ignition off, the cooler will shut off automatically when the power supply voltage drops below a set level. The cooler will turn back on once the battery is charged to the restart voltage level. The compressor will restart automatically in a few minutes when the voltage returns to normal values.
Note: these values are measured at the input of the control unit and / or at the DC connection.

  1. Battery protection function for the cooler with three-class battery protection function, can automatically check the battery voltage of the vehicle, before the electricity consumption will affect the normal functions of the car. The cool box will stop automatically to ensure that the car’s battery does not run out.
  2. Method for adjusting the battery protection:


    12V 24V
    Cut off (V) Cut in (V) Cut off (V) Cut in (V)
    Low 9.6V 10.9V 21.3V 22.7V
    Middle 10.4V 11.7V 22.8V 24.2V
    High 11.1V 12.4V 24.3V 25.7V
