What will the Westinghouse 12500W Dual Fuel run?
The Westinghouse 12500W Dual Fuel makes 9,500 running watts and 12,500 starting watts on gasoline or propane. On the generator makers' wattage charts that runs a well pump, a sump pump, a furnace blower, a refrigerator, a freezer, a microwave, lights, Wi-Fi and a TV at the same time, using about 5,846 of its watts.
9,500 running watts on gasoline (8,500 on propane), a key-fob remote start, automatic CO shutdown, and both a 30-amp L14-30R and a 50-amp 14-50R outlet for a transfer switch.

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 12,500 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 Westinghouse 12500W 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 9,500 running and 12,500 starting watts.
Can the Westinghouse 12500W 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 9,500 running and 12,500 starting watts. A well pump is wired in, so it needs a transfer switch fitted by a qualified electrician.
Can the Westinghouse 12500W 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.
