Explorer Bear UR55W 58Q/55L Dual Zone 12V/24V Portable Battery Powered Electric Fridge Freezer Powered by LG Compressor

Who this fridge is for

The UR55W is built to run away from a wall outlet — in your vehicle, off-grid, or as backup cooling during a power outage. It holds 58 quarts (55 liters), split across two separate cooling zones, and runs on AC power, a vehicle's 12V/24V port, battery, or solar, so it keeps working whether you're parked, driving, or fully off-grid. It also cools as low as -4°F, so it can hold true freezer temperatures, not just fridge-cold.

It's not the right pick if you want a small single-zone cooler for a quick day trip — its two-zone layout and four power options are built for longer, more flexible off-grid use, not a fast errand where a compact single-zone cooler would do.

How to choose your setup

Since the UR55W runs on four different power sources, the main decision is matching it to how you'll actually power it: a home or vehicle AC outlet, a 12V/24V port, battery, or solar. The second is temperature: with two zones you can set to different temperatures, you can run one zone colder than the other instead of cooling the whole 58-quart space the same way. Battery runtime depends on how cold you run it — two 170Wh batteries hold 40°F for up to 48 hours, or -4°F for up to 16 hours, since deeper cooling draws more power — so plan your battery or power access around whichever setting you'll use most.

Spec highlights

• Capacity: 58 quarts / 55 liters across two cooling zones.
• Cooling speed: pulls down from 77°F to 32°F in 15 minutes with its LG compressor.
• Battery runtime: up to 48 hours at 40°F or up to 16 hours at -4°F on two 170Wh batteries.
• Power flexibility: runs on AC 100-240V, DC 12V/24V, battery, or solar.
• Battery as power bank: each 170Wh battery has its own Type-C and USB port, so it can charge a phone or other small device while it powers the fridge.
• Efficiency: uses less than 0.5 kWh per day, even in MAX mode.
