When it comes time to carry extra food and beverages, preserve game meat or store medications in a vehicle, a cooler is indispensable. But even the best units rely on store-bought ice, and 12-volt, diode-based cooler/warmers don’t offer markedly better performance. Enter compact fridge/freezers powered by motorized compressors from onboard outlets. Commonplace in overland rigs, such units are well-represented in the line from ARB, which includes a 50-quart model measuring 20"x15"x28" and weighing just under 50 lbs. Separate cords allow it to operate from either 12-volt or 120-volt sources and cool from 50º to 0º F. Features include touch-pad controls, integrated battery-protection, a removable lid, an interior basket and an interior light. Price: $924. arbusa.com.
