Colku DC21DRG 21L Drawer Refrigerator: Built for Life on the Road

When you spend long hours on the road or off the beaten path, a reliable refrigerator is more than a convenience. It’s a necessity.
The Colku DC21DRG 21-liter drawer refrigerator is designed specifically for trucks, off-road vehicles, RVs, campers, and boats where stability, low power consumption, and space efficiency matter.

Drawer-Style Design for Built-In Installation

Unlike traditional upright portable fridges, the DC21DRG features a drawer-style design that fits seamlessly into vehicle cabinets and custom interiors.
Its reinforced bottom frame allows secure mounting, keeping the refrigerator stable even on rough or uneven roads.

This makes it an ideal choice for professional drivers and vehicle conversions where every inch of space counts.

One Zone, Full Cooling and Freezing Capability

The DC21DRG uses a single-zone temperature system that covers both cooling and freezing needs:

• Temperature range from -18°C to +10°C

• Rapid cooling mode quickly drops to -18°C

• Suitable for freezing meat, ice cream, and even making ice

• Perfect for everyday refrigeration of drinks, fruit, and ready-to-eat food

For most vehicle users, one well-controlled zone is all you need.

Built to Handle Bumps and Off-Road Conditions

This refrigerator is equipped with a shock-resistant compressor designed to operate reliably during constant vibration.
Whether you’re driving on gravel roads, construction sites, or off-road trails, the cooling performance remains stable.

It’s built for real driving conditions, not just smooth highways.

Low Power Consumption with Battery Protection

Power efficiency is critical for vehicle-based appliances.
The DC21DRG supports 12V / 24V DC power and includes a three-level battery protection system:

• Prevents excessive battery discharge

• Automatically adjusts based on vehicle voltage

• Helps ensure your vehicle can always restart safely

You can use the refrigerator overnight without worrying about draining the battery.
