Two Ways to Buy the Explorer Bear UR55W
The Explorer Bear UR55W is a 55L/58-quart dual-zone portable fridge freezer built for travel, overlanding, and off-grid stops. It runs on AC power (100–240V), DC power (12V/24V), battery power, or solar, and it is offered in two purchasable configurations: Plug-in Unit Only, and 1 Unit + 2 Batteries Combo. The table below compares what each configuration actually includes, so you can match the setup to your trip.
Configuration Comparison
| Axis | Plug-in Unit Only | 1 Unit + 2 Batteries Combo |
|---|---|---|
| What's included | Fridge/freezer unit only | 1 fridge/freezer unit and 2 batteries |
| Capacity | 55L / 58 qt | 55L / 58 qt |
| Dual-zone storage | Dual zone — separate refrigerated and frozen compartments | Dual zone — separate refrigerated and frozen compartments |
| Power sources | AC 100–240V, DC 12V/24V, or solar (batteries sold separately) | AC 100–240V, DC 12V/24V, solar, or the two included 170Wh batteries |
| Cordless runtime | None included — depends on an external AC/DC/solar source | Up to 48 hours at 40°F, or up to 16 hours at -4°F, on the two included 170Wh batteries |
| Extra function | — | Each battery also works as a power bank with Type-C and USB ports |
Which Configuration Fits Your Trip
Both configurations share the same 55L/58-quart dual-zone interior and the same LG compressor, which cools from 77°F to 32°F in 15 minutes while drawing less than 0.5 kWh per day even in MAX mode. The difference between the two configurations is about how the fridge gets its power on the road.
- Shorter trips with a reliable outlet: If your trip keeps you near a running vehicle's DC outlet, shore power, or a solar setup for most of the drive, the Plug-in Unit Only configuration already covers that use case, since the unit runs on AC 100–240V, DC 12V/24V, or solar without any batteries attached.
- Multi-day, off-grid, hot-weather stops: If the trip includes stretches where the vehicle is off and there's no outlet or panel to plug into, the 1 Unit + 2 Batteries Combo adds up to 48 hours of runtime at 40°F (or 16 hours at -4°F) directly from the two included 170Wh batteries, so the dual-zone compartments can keep running cordless.
Neither configuration changes the fridge's dual-zone function or its 55L/58-quart capacity — the choice is about whether you want the battery power source bundled in from the start, or plan to rely on your vehicle, shore power, or solar for most of the trip.
