Checking Charge Status

When the refrigerator is powered ON and DC/AC power is connected, the battery icon on the display screen will flash to show charging. To charge the fridge/freezer battery without running the compressor, simply connect the adapters without powering "ON" the fridge. To view charging status, press and hold the [settings] button for 3 seconds. The fridge's battery status and voltage will be displayed. When the voltage reaches 12.6V and the battery icon stops flashing, the unit has been fully charged and wiring should be disconnected to prevent internal component damage.

Warning: Do not charge fridge/freezer with DC 12V and Solar Panel at the same time! The fridge could be seriously damaged and pose a potential hazard to you.

AC Charging Management

If the fridge has not been used for a long time, the battery may be discharged, and the fridge will not power on. Use the AC adapter to charge the fridge battery and run the fridge. After the fridge battery has charged up to 30%, you can switch to other methods for charging.

Car Cigarette Lighter Charging Management

The product has a three-level battery protection function, which guarantees the normal operation of the product and protects the vehicle's battery. When in the power-on state, long press the [settings] button for 3 seconds and the display screen flashes H, select low voltage production L(ow), M(edium), and H(igh) by clicking the [settings] button. The factory default is set to High protection.

H should be set when the product is connected to car power, and M or L should be set when it is connected to a portable battery or other back-up battery. Because of the different output voltages between vehicles, the battery protection level can be set from H to M or from M to L if there is a voltage protection code F1 shown on the panel. The battery protection level should be set to H if the product will keep working after turning off the car engine, or the product may drain the battery.

Solar Charging Management

To ensure your fridge is being charged by a solar panel, turn the fridge on first. The battery icon will flash on the display screen to show the charging status. The fridge can be turned off while it is being charged. Press and hold the [settings] button for over 3 seconds to check the battery status and voltage. An extension cable may be required to keep the fridge in a cool place (to avoid overheating) while the solar panel is in the sun. Input power for charging should be higher than the refrigerator power draw (about 40-45w), otherwise the optional battery will not charge at the same time. To ensure that solar charging power is higher than refrigerator working power, a 100-Watt solar panel is advised.

Battery Usage

• Optional Removable Battery: The lithium battery is back up power to keep the refrigerator working for short periods while off grid.
• Notice: When not using the battery power or fridge for a long time, please turn off the battery output. (Hold [settings] button for 3 Sec).
• Maintain Battery Charge:
  1. Home / Hotel: Use AC adapter to charge unit from AC outlet.
  2. Car / Boat: Use DC port to power the fridge and charge the battery.
  3. Outdoor: Charge the battery with a solar panel (optional). Portable 12V power system / solar with / or petrol generator would be good companion.
• Extended battery usage:
  1. Cool down the fridge before your journey: It is always suggested to charge fridge battery and cool the fridge down in advance with the mains to DC adapter from the wall outlet the day before the trip. To prepare for off-grid fridge usage, place food and beverages inside fridge for cooling the day before. This will not only keep the optional battery more durable, but also save energy for outdoor activities once on battery mode.
  2. Disconnecting the Battery: The battery can be removed or disconnected with the side button. This prevents the battery from discharging. The product will work from the AC adapter or car outlet without the optional battery installed. Note: Please charge fully the optional battery before it is put into storage 1 month or more.

Food Storage

• Freezer (-4° F~32° F)(-20°C~0°C):
  1. Meat should be cut and packed properly when placed in the fridge.
  2. Do not put the fresh food and frozen food together.
  3. Do not store glass containers or other containers which seal in liquid in the freezer, to avoid explosion.
• Refrigerator (32°F~50° F)(0°C~10°C):
  1. Egg, butter, milk and bottle drinks can be stored.
  2. All food should be packed appropriately before being stored in the fridge.
  3. Place food in refrigerator after it gets cool in order to save energy.
