What it is
The Westinghouse WGen5300DFc is a mid-size dual-fuel generator built around a 274cc Westinghouse OHV engine with a cast iron cylinder sleeve. On gasoline, it delivers 5,300 running watts and 6,600 starting watts. On propane, output drops to 4,800 running watts and 5,900 starting watts. A 4.7-gallon fuel tank with a built-in gauge supports up to 14.5 hours of runtime, and push-button electric start pairs with a wireless remote key fob, backed by a recoil pull if the battery is ever dead.
The control panel includes a 120V 20-amp household duplex outlet, a 120V 30-amp RV-ready outlet (TT-30R), and a 120/240V 30-amp transfer-switch-ready outlet (L14-30R), along with a voltage selector switch to choose between 120V-only or 120/240V operation for higher-voltage appliances like a well pump. This model, WGen5300DFc, adds Westinghouse's CO sensor and automatic shutdown, a feature the earlier WGen5300DF this unit replaced did not have.
Why it works
This generator sits in a genuinely useful middle ground between light camping inverters and full whole-home units:
Real household capacity, not just camping power
At 5,300 running watts, this generator can carry a refrigerator, a sump pump, a well pump, and lighting at the same time, the kind of load that the small inverters reviewed elsewhere on this site are not built to handle. Westinghouse specifically markets it for sump pumps, air conditioners, refrigerators, and well pumps together, not as a list of things it can technically power one at a time.
Both transfer-switch and RV outlets, without an adapter
The L14-30R outlet connects directly to a manual transfer switch for home circuit backup, while the separate TT-30R outlet covers RV use at the same time. You are not choosing between the two or buying an adapter to get both.
Dual fuel with mid-run switching
Gasoline degrades in storage without stabilizer, while propane stores indefinitely. This generator switches from gas to propane without shutting down first, which matters if a gasoline supply runs low mid-outage and propane is the fuel left on hand.
The one thing to know
Carbon monoxide safety is non-negotiable
Portable generators produce carbon monoxide, an odorless gas that can reach lethal concentrations indoors within minutes. The CPSC recommends placing any portable generator at least 20 feet from all doors, windows, and vents, with the exhaust pointed away from the home. Never run a generator indoors, in a garage, on a covered porch, in a carport, or in any enclosed or partially enclosed space, even with doors or windows open. Westinghouse's CO sensor provides a backup shutoff if carbon monoxide reaches dangerous levels near the unit, but it is not a substitute for correct placement. Install battery-operated CO detectors on every level of your home.

Not sold in California, and heavy enough to plan for
This model is EPA compliant but not CARB compliant, and Westinghouse does not sell it for use in California. Separately, at 135.6 pounds dry, this is not a one-hand carry. It ships with a wheel kit and folding handle, which helps, but plan for two people or a ramp to load it into a vehicle.
The other thing to know is noise. At 68 dBA, this is a conventional generator, not an inverter, and it runs louder than the small inverters reviewed elsewhere on this site. For a generator that will run for hours or days during an outage, that difference is the one your neighbors will notice.
Alternatives worth knowing
DuroMax XP11000iH, for more wattage and clean inverter power
Substantially more running wattage (9,000W) as a true inverter with lower THD, at a higher price. The right choice if you need more headroom or plan to run sensitive electronics directly off the generator. Read our review.
Generac GP9500E Tri-Fuel, for a third fuel option
More running wattage (9,500W) and adds natural gas as a fuel source, useful for a home already piped for gas, at a similar noise level. The right choice if fuel flexibility and maximum wattage both matter. Read our review.
Pulsar PGDA70BiSCO, for clean power and CARB compliance
More running wattage (6,000W) as a true inverter that is also CARB compliant, at a fraction of this Westinghouse's weight. The right choice if you want clean power or live somewhere this model cannot be sold. Read our review.
Maintenance
Run the generator under load for 15 to 30 minutes every 30 days to keep the engine and fuel system in working order. Use fuel stabilizer for any gasoline storage period longer than 30 days. Propane does not require this step.
Check the oil level before every use; the automatic low-oil shutdown helps prevent engine damage if it runs low. Follow the manual's schedule for oil change intervals, and inspect the air filter and spark plug annually. Keep the electric start battery charged or disconnected during long storage so it holds a charge when needed.
Westinghouse backs the WGen5300DFc with a 3-year limited warranty and lifetime technical support through its nationwide service network. Register the unit and keep the purchase receipt with your household documents.
NWS recommendation
If your household needs to run a refrigerator, a sump pump, and a well pump or window AC together during a multi-day outage, and you also want an RV-ready outlet for the same generator, the WGen5300DFc covers both jobs without compromise. Pair it with a manual transfer switch, keep gasoline fresh with stabilizer or store propane instead, and place it at least 20 feet from the house with the exhaust pointed away.
