Compact 4L Storage

Sometimes you don't need a giant cooler.

The CROWNFUL gives you 4 liters of personal storage space in a compact package that's easy to fit into smaller spaces.

The interior can accommodate up to:

6 × Standard 12 oz Beverage Cans

Use the removable shelf to organize smaller items or remove it when you need additional vertical space.

It's an easy size for keeping a few favorite drinks, snacks, or personal items nearby without hauling around a full-size cooler.

Cool on the Road

Connect the included 12V DC power cord to a compatible vehicle accessory outlet and bring cooling capability along for the drive.

It's a convenient option for:

• Road Trips

• Camping Trips

• Long Drives

• RV Travel

• Boating

• Tailgating

• Day Trips

• Outdoor Adventures

For vehicle operation, the vehicle engine should be running while the refrigerator is powered.

Do not leave the refrigerator operating from the vehicle's 12V outlet with the engine off, as prolonged operation may discharge the vehicle battery.

Cooling Performance

This is a thermoelectric mini fridge rather than a compressor refrigerator.

Instead of maintaining one exact refrigerator temperature regardless of conditions, its cooling performance is relative to the temperature of the surrounding environment.

The unit is designed to cool its interior approximately:

32–40°F below ambient temperature

For example, if the surrounding temperature is approximately 77°F, the interior may reach approximately 37–45°F under suitable operating conditions.

For best results:

• Start with pre-chilled drinks or food whenever possible.

• Keep the door closed as much as possible.

• Keep the refrigerator away from direct sunlight.

• Maintain adequate airflow around the ventilation openings.

• Avoid placing the unit next to major heat sources.

Ambient temperature and operating conditions will affect actual cooling performance.

Cool or Warm

Cold isn't the only option.

Flip the control to WARM and the CROWNFUL can maintain appropriate preheated contents at temperatures up to approximately:

149°F / 65°C

That gives one compact appliance two different functions.

COLD

Great for keeping pre-chilled drinks, appropriate snacks, and temperature-compatible personal products cool.

WARM

Designed primarily to help maintain the temperature of items that are already warm.

The warming function is not intended to replace a microwave, oven, stove, or other dedicated cooking appliance.

AC + DC Power

Use it at home.

Bring it on the road.

AC Power

Connect the included AC cord to a compatible standard household outlet.

12V DC Power

Connect the included DC cord to a compatible vehicle 12V accessory outlet.

That dual-power capability makes this little refrigerator especially useful for road trips and travel.

Quiet Enough for Personal Spaces

A refrigerator doesn't need to sound like one.

The thermoelectric system uses a brushless fan motor and is designed for quiet operation, making the fridge suitable for spaces such as:

• Bedrooms

• Offices

• Dorm Rooms

• RVs

• Home Offices

CROWNFUL rates its Sleep Mode noise level at approximately 25 dB.

Not Just for Drinks

The removable shelf and compact interior make the CROWNFUL useful for more than soda cans.

Depending on the individual product's storage requirements, it may be useful for:

• Drinks

• Snacks

• Skincare Products

• Face Masks

• Cosmetics

• Appropriate Personal-Care Products

• Other Temperature-Compatible Items

Always follow the storage instructions supplied by the manufacturer of anything placed inside the refrigerator.

Important Use Information

This is a thermoelectric cooler/warmer and does not operate like a traditional compressor refrigerator.

Cooling performance depends on ambient temperature and operating conditions.

For best cooling performance, place pre-chilled items inside the unit whenever possible.

Maintain adequate ventilation around the refrigerator. Do not block the rear or side ventilation openings.

When using the refrigerator in a vehicle, start the vehicle before connecting the refrigerator to the 12V outlet and disconnect it before turning the vehicle off.

Running the refrigerator while the vehicle is off may discharge the vehicle's starting battery.

Allow the unit to remain OFF for at least 30 minutes before switching directly between COLD and WARM modes.

Do not immerse the refrigerator, cords, or electrical connections in water.

This refrigerator is not intended to cook food.

Do not store medications, temperature-sensitive medical products, or other items requiring a precise controlled temperature unless the product manufacturer specifically confirms that the refrigerator's operating range and temperature stability meet those requirements.
