What will the DuroMax XP5500EH run?
The DuroMax XP5500EH makes 4,500 running watts and 5,500 starting watts on gasoline or propane. On the generator makers' wattage charts that runs a furnace blower, a refrigerator, a freezer, a sump pump, lights, Wi-Fi and a TV at the same time, using about 3,326 of its watts.
4,500 running watts covers a refrigerator, a furnace blower and a sump pump together on our sizing chart, on gasoline or propane, with electric start. An open-frame generator, so louder than the inverters here.

Cautious running and starting watts from Champion's and DTE Energy's wattage charts. "Check": it runs once started, but the charts' start-up surge is more than its 5,500 starting watts, so read your appliance's label (amps × 120 = watts). Wired-in loads need a transfer switch fitted by a qualified electrician. Your own list: the generator calculator.
Questions
Can the DuroMax XP5500EH run a refrigerator?
Yes. A refrigerator needs up to about 750 running watts and 2,600 to start on the charts, within its 4,500 running and 5,500 starting watts.
Can the DuroMax XP5500EH run a well pump?
Yes. A 1/3 to 1/2 HP well pump needs up to about 1,000 running watts and 3,000 to start on the charts, within its 4,500 running and 5,500 starting watts. A well pump is wired in, so it needs a transfer switch fitted by a qualified electrician.
Can the DuroMax XP5500EH run central air?
No. DTE Energy's guide puts a 3-ton central air conditioner at 6,000 running watts and about 18,000 watts to start. That takes a standby generator.
