Real-world differences
The power difference is smaller than the feature difference
Only 300 rated gasoline watts separate them, but dual fuel and remote start fundamentally change ownership. If you never intend to store propane or use remote start, paying for those features may not help.
Runtime claims use different loads
WEN's published runtime example is at half load while Westinghouse quotes up to 18 hours at 25% load. Do not compare the hour numbers without the load percentage.
Both are rollable, not suitcase-light
These are in the larger inverter class. For frequent lifting, look at the new sub-60-pound 4,000–4,500W models instead.
Who should buy which?
Buy the WEN if…
You want straightforward gasoline inverter power, electric start and an RV outlet at a value-oriented price.
Buy the Westinghouse if…
Propane backup, remote start, a larger fuel tank and slightly more running power justify the added cost.

Price, parts, and ownership cost
Purchase price is only one part of the decision. Budget for the oil and service parts specified in the manual, a weather/storage cover, correctly rated cords, fuel containers or propane equipment, and any model-specific parallel or RV hardware you actually need. Electric- and remote-start models also add a battery that has to remain healthy during storage. For emergency use, parts availability and local service can matter more than saving a small amount at checkout.
When comparing marketplace listings, match the exact model number rather than only the wattage in the title. Generator families often contain several revisions with different starting systems, CO-shutoff hardware, outlet panels, CARB status, included propane hoses, or parallel-kit compatibility. A lower price is not a bargain if the listing is an older revision that lacks a feature your plan depends on. For used generators, ask about hours, storage fuel, oil-service history, load testing, and whether the inverter or voltage-regulation system has been verified under load.
Generator safety is not optional
Portable generators are combustion engines. The U.S. Consumer Product Safety Commission says to operate them outside only, at least 20 feet from the home, with exhaust pointed away from the home and other occupied buildings. A garage, shed, carport, porch, basement, crawlspace, or partly enclosed area is not made safe by opening doors or windows. Install and maintain carbon-monoxide alarms on every level of the home and outside sleeping areas.
For home circuits, do not improvise a connection and never backfeed a house through a receptacle. A transfer switch or properly approved interlock/inlet arrangement should be selected and installed in accordance with the generator manual, electrical code, utility requirements, and qualified professional guidance. For rain or snow, follow the manufacturer's weather instructions rather than moving a running unit into an enclosure.
Output ratings also change by fuel. Propane and natural gas commonly produce less power than gasoline, so size the system around the fuel you actually expect to use. Verify the appliance nameplate, motor starting behavior, voltage, receptacle type, and generator manual before purchase.
FAQ
Is the WEN 56380i dual fuel?
No. The 56380i referenced here is a gasoline inverter generator.
Which is better for outages?
The Westinghouse's propane option gives more fuel flexibility, while the WEN remains a capable gasoline inverter for critical loads. The better fit depends on your stored-fuel plan.
Do both support RV use?
Yes. Both include a TT-30R RV-ready receptacle.
