Adapter Connect the car cigarette lighter
Connect the car refrigerator
1.The refrigerator can be connected to more than one energy source.
2.The refrigerator can connect directly to the DC12V/24V power supply.
3.If the refrigerator is used an AC100-240V power supply, an AC adapter should

Car Refrigerator Operation
Car battery protection voltage reference:
Built-in ECO electronic control module can automatically monitor car
battery voltage. The refrigerator will be automatically cut off when the power is
excessively consumed, protecting the battery consumption from being too low to
affect auto-ignition.

Description
Explanation
1
Switch the fridge on when the button is pressed briefly.
Switch the cooler off when the button is pressed again.
2
Press briefly to select MAX or ECO.
In MAX mode, the compressor runs fast to reduce
temperature rapidly. In ECO mode, the compressor runs
slowly to save energy.
3
Press briefly to increase the set temperature by 1 degree.
Press continuously to increase the temperature fast. The
maximum setting can be 10 ℃, and the minimum setting
can be - 20 ℃(The default value for the initial startup is
- 5 -
0℃/32 ℉).
4
Press briefly to decrease the setting temperature by 1
degree. Press continuously to decrease temperature fast.
The maximum setting can be 10℃, and the minimum
setting can be - 20℃(The default value for the initial
startup is 0 ℃/32 ℉).
5
Press simultaneously for 3 seconds to change
temperature unit between℉and ℃. Please make sure no
symbol is flashing when you use this function.
Function Introduction
Battery Protection Setting (The factory default voltage isH1)
1.Battery Protection Levels: H (High)>L (Low) >M (Medium)
2.Press the key for 3s to enter the battery protection setting. Press the key again to
switch H>L>M levels in turns.
3.If no operations were detected, the set level will flash for 3s, then exit and save
the current setting.
Power-off Memory Function
There is a power-off memory function for car refrigerators. When the power is lost,
the working state (On/Off status, working mode, etc.) before power-off can be
automatically recovered at the next startup; no need to set it again.
ECO: Energy-saving cooling MAX: Powerful cooling.

Simple Fault Analysis
Advice: If abnormal situations cannot be resolved through a simple fault analysis,
please get in touch with professional customer service for assistance.
Car Refrigerator Does Not Work
1.Check if the power is connected correctly. (check If the plug is loosened or
positive and negative poles are reversed).
2.Check if the power switch on the operation panel is turned on.
3.Check if the cooling ventilation is normal.
4.Check if the fuse is blown.
Poor Cooling Performance
1. Check if the lid is closed correctly.
2. Check if the door seal is damaged or deformed.
3. Check if there is poor ventilation around the fridges.
4. Check if the temperature is set correctly.

Condensation on Refrigerator Surface
When the ambient air humidity exceeds 75%, slight condensation will occur on the
box surface, which is normal.
Failures and Solutions
△E1: Low Input Voltage
Failure 1: Insert the refrigerator power cord into the cigarette lighter before the car
starts. Solution 1: Wait a while to connect the car after it starts.
Failure 2: The input voltage of the adapter is too low.
Solution 2: Adjust the battery protection level to middle-voltage or low-voltage. If it
doesn't work, please replace a new adapter.
△E2: Fan Fault
Please replace a new fan when you identify there is a fan malfunction.
△E3: Input Voltage Fault Due to Compressor Frequently Start
When the refrigerator is used in the car, and E3 appears, Please shut it down for 5
minutes and restart it.
If it doesn't work, that can be identified to be El fault; please solve it according to
the solution of El.
When the refrigerator is connecting with the adapter and E3 appearing
①Please adjust the battery protection level to the middle or low level.
②If it doesn't work, please replace a new adapter.
△E4: Low Rotational Speed of Compressor
Please adjust the input voltage and repower it.
△E5: Overheating of Controller Chip
- 8 -
Please power off for 5 minutes and check if the lousy ventilation around the
compressor causes the overheating.
Use Suggestions
1. If equipped with a backup battery, you can maintain any temperature you set
under any circumstances without worries.
2. When placing ice cream, please adjust the temperature to the lowest; it must be
powered on for a long time.
3. Prevent the health problems of drinking bottled water caused by high
temperatures.
4. Frozen food, rare seafood, and vehicle-mounted refrigerators let frozen fresh
food accompany the journey.
5. Healthcare products, insulin, and imported drugs need to be refrigerated, and
the precise temperature control of onboard refrigerators will escort health along
the way.
6. The tea leaves are effectively kept fresh in the car refrigerator, and you can
drink fresh and delicious tea anytime during the self-driving tour.
7. The best storage temperature of red wine is 10 ℃- 18 ℃(50 - 64.4 ℉). The
precise temperature control of the car refrigerator can effectively ensure the
storage temperature of red wine.
8. The storage time of high-grade fruit in the car at high summer temperatures will
be at least 2 hours. The storage time is shorter even if the air conditioner is turned
on. Using a car refrigerator can effectively preserve high-grade fruit.
9. The coating of high-grade sunglasses will fall off under the high temperature in
summer. The car refrigerator is an ideal place to place it.
10. High-grade cosmetics quickly deteriorate under high temperatures in the car.
Carry cosmetics with the car; the car refrigerator will be your better choice.
