There are portable coolers and then there’s the ARB refrigerator/freezer designed specifically for extreme outdoor use. The unit’s 50-quart-capacity compressor can keep ice from melting, even on 90 F days, while drawing less amperage than required to power a single headlight, says ARB. You can plug in to your vehicle’s 12-volt power source or a 120-volt wall socket (the refrigerator is also solar-panel- and generator-compatible). The interior includes separate compartments for fruit and dairy products plus a removable shelf for chilling larger items. The ARB fridge retails for $924, not including an optional insulated canvas transit bag that costs an extra $146. Get more information at www.arbusa.com.
