Craftsman CMXGGAS030729 3500-Watt Gasoline Portable Generator

Powered by the Generac 149cc, OHV engine, the Craftsman 3000i is a superbly reliable machine. It delivers the inverter supplied 3,000 peak watts and 2,300 running watts with absolute ease. Fuel economy is reasonable. At 4.9 kilowatt-hours per gallon, the Craftsman 3000i is about average for a generator of this size.

The total wattage you need to run a small refrigerator would be 1400 watts, so you would need a generator that provided at least that many watts. Tip: For best results, always use a generator that can comfortably handle all your power needs while using no more than 90 percent of its capacity.
