Introduction to Product Functions

Before using the refrigerator, please read this manual carefully. Keep the manual for future reference.

• Before using your refrigerator for the first time, clean it inside and out with a damp cloth.
• Do not fill the refrigerator with corrosive liquids. Do not pour liquids directly into the refrigerator.
• When the refrigerator will not be used for a long time, please disconnect the power supply and keep the refrigerator dry.
• Please clean the inner compartment regularly to prevent bacteria and odors from forming, and to ensure food safety.
• Shut down the refrigerator and battery (if used) before pulling the refrigerator by the handle.

Connect the power supply.

• Find the DC power cord in the box. Connect the DC plug to the power outlet of the car refrigerator.
• Please place the refrigerators in the back-up of the car, seats, etc.
• Lay out power cords to suit the interior space of your car. Insert the cigarette lighter plug (one side of the power cord) into the car cigarette lighter hole.
• Press the power button to turn it on.

A textual description of the image shows a car cigarette lighter, a DC power cord, and the car refrigerator (standard style).

The refrigerator can be connected to more than one source of power. The refrigerator can be directly connected to the 12V/24V DC power supply. If the refrigerator is used with a 100–240V power supply, an AC adapter should be used.

Car Refrigerator Operation

Car battery protection: voltage reference

The built-in Eco electronic control module can automatically monitor your car battery's voltage. The refrigerator will automatically shut off when excessive power is consumed, thereby preventing draining the battery or interfering with starting your car.

Note: When the refrigerator is running, "off" or "on" indicates the stop or start of the compressor.

Parts schematic

1. Compressor cover, 2. Power inlet, 3. Recessed handle, 4. Control panel, 5. USB port, 6. Battery slot, 7. Battery slot cover, 8. Door gasket, 9. Storage compartment, 10. Removable divider.

A diagram shows the parts of the Euhomy car refrigerator, labeled 1 through 10.

Optional Operation Method

A diagram illustrates the control panel with buttons for ON/OFF, Battery protection level, Setting, Power/Voltage, Increase temperature, Temperature display (MAX/ECO), Decrease temperature, and Compressor running symbol.

Battery protection setting (factory default voltage is H)

• Battery protection levels: H (high) > L (low) > M (medium)
• Press for 3 seconds to access the battery protection setting. Press the button again to switch between H, L, and M.
• The set level will flash for 3 seconds, then exit and save the current setting.

Battery Protection Setting (factory default voltage is H)

• The on-board refrigerator has the power failure memory function. When the refrigerator is powered off, the working state (ON/OFF, working mode, etc.) before the shutdown can be automatically restored at the next startup without resetting.

ECO: Energy-saving cooling MAX: Powerful cooling

Removable partition

• A partition can be inserted in the middle of the compartment. This partition serves only to divide the compartment for easy organization of items. It should be noted that the presence or absence of the partition does not change the function of the device or the temperature display.

Using the Detachable Battery and Solar Charging Port

Battery installation (Batteries need to be purchased separately.)

• Open battery slot cover.
• Press the battery button continuously until the indicator lights up.
• Press the power button to turn on the fridge.
• Tip: Please set battery protection level to "L" if you are using the battery. If the control panel displays "E1" then the charge in the battery is low.
• Press battery button continuously to switch off the battery. Do this when you don't need the battery or plan to store the fridge.
• Squeeze the two battery holders to take out the battery.

A diagram shows the battery installation process in three steps (1, 2, 3). It also labels the Power indicator, Power holder, and Battery button.

Charge the battery

• Keep the battery in the slot.
• Connect the fridge with 12V/24V power by cigarette lighter power cable or home socket by AC/DC adapter.
• The battery will charge even though the fridge is not switched on.

WARNING!!! Please do not charge the battery in temperatures higher than 109 °F

Problems and Troubleshooting

Advice: In the case of any abnormal situation that cannot be resolved through simple fault analysis, please contact Customer Service for assistance.

Car refrigerator does not work

• Check that the power is connected properly. (Check if the plug is loose or positive and negative poles are reversed.)
• Check that the power button on the control panel is turned on.
• Check that the cooling ventilation is normal.
• Check if the fuse is blown.

Poor cooling performance

• Check that the lid is closed properly.
• Check if the door seal is damaged or deformed.
• Check if there is poor ventilation around the fridge.
• Check that the temperature is set properly.

Abnormal noise

• Refrigerator is not set on a flat, level surface.
• Check for vibrations in surrounding objects.
• Parts inside the refrigerator have come loose or fallen off.

Refrigerator condensation

It is normal for some condensation to collect on the surface of the refrigerator when humidity is more than 75%.

Definition of error codes

Refrigerator is not put on a flat level surface. Check for vibrations in surrounding objects.

Failures and Solutions

E1: Low input voltage

• Failure 1: Refrigerator power cord was inserted into cigarette lighter before the car started. Solution 1: Wait to connect the fridge until after the car is started.
• Failure 2: Input voltage of the adapter is too low. Solution 2: Adjust the battery protection level to M or L. If this does not work, replace the adapter.

E2: Fan fault

• Please replace the fan when a fan malfunction has been indicated.

E3: Input voltage fault due to compressor starting and stopping frequently

• When the refrigerator is used in a car and E3 appears: Please shut down the refrigerator for 5 minutes and then restart it. If this does not work, please see E1 for solutions.
• When the refrigerator is connected via adapter and E3 appears: Please adjust battery protection level to M or L. If this does not work, please replace the adapter.

E4: Low rotational speed of compressor

• Please adjust the input voltage and restart the refrigerator.

E5: Overheating of controller chip

• Please power off the refrigerator for 5 minutes. Check to see if the overheating may be caused by poor ventilation around the compressor.
