A patented “swing motor” compressor makes this 12-volt/110-volt purpose-built boat refrigerator/freezer different from the rest. With one efficient moving part, it draws only .7 amp when maintaining frozen contents and only 3.3 amps when it’s freezing contents. Raise the thermostat to use it as a fridge. At .7 amp, it can easily be powered by solar panels. It can automatically sense availability of 110V power and switch to it, and switch back to DC power when 110V is unavailable. $730; 561-743-7419
