What will the Champion 4500W Dual Fuel run?
The Champion 4500W Dual Fuel makes 3,500 running watts and 4,500 starting watts on gasoline or propane. On the generator makers' wattage charts that runs a refrigerator, lights, Wi-Fi, a TV and phones at the same time, using about 1,046 of its watts.
3,500 running watts is enough to run a fridge, a furnace fan, lights and chargers together, and it runs on gasoline or propane, so you can store fuel that doesn't go stale the way gasoline does. At nearly 100 lb it lives on its wheels, not in a car trunk.

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 4,500 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 Champion 4500W Dual Fuel run a refrigerator?
Yes. A refrigerator needs up to about 750 running watts and 2,600 to start on the charts, within its 3,500 running and 4,500 starting watts.
Can the Champion 4500W Dual Fuel 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 3,500 running and 4,500 starting watts. A well pump is wired in, so it needs a transfer switch fitted by a qualified electrician.
Can the Champion 4500W Dual Fuel 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.
