Battery charging (for reference only):
Charge in the refrigerator(in standby mode)
Wall outlet AC 100~240V(using dedicated adapter) (Charging time≈8h)
Car cigarette lighter DC 12/24V(When the Input voltage>13.5V, charging time≈8h)
Solar 12~50V (Connect to the "SOLAR" port of the refrigerator) (When using 100W solar panel,
charging time≈5h)
Charge separately
Battery charger (optional) (Connect to the DC charging port of the battery) (Charging time≈8h)
Charging station (optional)
(Charging time of a single battery≈4h)
Note: It is suggested to switch off the refrigerator when charging the battery (the power supply may
mainly power the compressor when the refrigerator is running).
When connect to a solar panel, please place the refrigerator in a cool place to dissipate heat. The
charging input power should be higher than the working power of the refrigerator(about 40-45W),
or switch off the refrigerator, otherwise the battery will run out.
It is suggested to use 100W solar panel.
MAX Solar Input Voltage: 50V; MAX Solar Input Current:10A.
Note: the output of the solar panel is unstable, so it cannot power the refrigerator directly. When
using a solar panel, the battery should be put into the refrigerator.
• Discharging time (for reference only): In the low battery protection mode, the battery can last
about 4 hours after being fully charged. When the temperature of the refrigerator is set between
2~8°C (ambient temperature 25°C), it can last 12 hours after the internal temperature stabilizes.
Remove or switch off the battery to prevent self-discharge when not in use.

• Switch off and unplug the device.
• Take out all the items stored in the device.
• Wipe off excess water with a soft rag.
• Put the device in a cool and dry place.
• Leave the lid slightly open to prevent odors from forming.
• Recommended storage environment:
ambient temperature: 25°C, ambient humidity: ≤ 75%.
■Defrosting:
Humidity can form frost in the interior of the cooling device or on the evaporator.

• Check if the switch is on.
• Check if the plug and socket are connected well.
• Check if the fuse has been burnt.
• Check if the power supply is malfunctioned.
• Switch on/off the fridge frequently may cause start delay of the compressor.
Refrigerator compartments are too warm
• The door is opened frequently.
• A large amount of warm or hot food was stored recently.
• The refrigerator has been disconnected for a long time.
Food is frozen
• The temperature was set too low.
There is "water flow" noise from inside the refrigerator
• It is a normal phenomenon, caused by the flow of refrigerant.

• It is a normal phenomenon; the noise will be reduced after the compressor works stably.
Code F1 displayed
• Possible cause: low voltage to fridge. Adjust the battery protection from High to Medium or from
Medium to Low.
Code F2 displayed
• Possible cause: condenser fan is overloaded. Disconnect power to fridge for 5 minutes & re-start.
If the code shows again, contact manufacturer for service.
Code F3 displayed
• Possible cause: the compressor starts too frequently. Disconnect power to fridge for 5 minutes &
re-start. If the code shows again, contact manufacturer for service.
Code F4 displayed
• Possible cause: compressor not kicking in. Disconnect power to fridge for 5 minutes & re-start. If
the code shows again, contact manufacturer for service.
Code F5 displayed
• Possible cause: overheating of the compressor & electronics. Disconnect power to fridge for 5
minutes & re-start. If the code shows again, contact manufacturer for service.
