WEN 6800-Watt Dual Fuel RV-Ready Electric Start may suit RV owners seeking an inverter generator with gasoline or propane operation and a bonded-neutral 240V configuration for low-power Level 2 EV charging. Verify vehicle and charging-equipment compatibility before relying on that function.
Westinghouse 14500 Peak Watt Dual Fuel Home Backup could fit buyers who want 11,500 gasoline running watts and dual-fuel operation, but it lacks the tri-fuel model’s listed natural-gas option.
How to Choose the Best Generator for Home Backup Power
1. Match running watts to the loads you will use
Running watts describe the output available for ongoing operation, while peak or surge watts cover brief startup demand. Make a list of the appliances and devices you intend to power, then check their rated and starting watt requirements against the generator’s specifications. Do not assume that a high peak-watt figure means the same amount is available continuously.
For example, the Westinghouse 6500 model lists 5,300 gasoline running watts, while the larger Westinghouse tri-fuel model lists 11,500. A battery station such as the Jackery is meant for a much smaller set of loads. Leave room for startup demands, and ask a qualified electrician to assess a planned whole-home or circuit connection.
2. Choose fuel based on access and storage
Gasoline, propane, and natural gas involve different supply plans. Gasoline models need an appropriate stored supply; propane models depend on compatible cylinders and the included or required hose; natural-gas operation depends on a suitable connection. A tri-fuel model offers more listed choices, but does not remove the need to plan for fuel availability and safe installation.
Check which fuel’s wattage figures apply. Some generators produce different output on propane than on gasoline. The Westinghouse 14500 tri-fuel listing gives gasoline output and runtime details, but the published data does not state equivalent output figures for propane or natural gas. Confirm those details with the manufacturer if a non-gasoline fuel will be your primary choice.
3. Verify outlet and transfer equipment compatibility
Outlet shape, voltage, and amperage affect what you can connect and how. A household receptacle can serve compatible plug-in equipment, while an L14-30R or 50A outlet may be used with appropriate transfer equipment. The phrase “transfer switch ready” does not mean a transfer switch is included. The Westinghouse WATS200 is sold separately, and other transfer switches or interlock kits also need to match the generator and home wiring.
Never connect a generator to a home by plugging it into a wall outlet. That practice can create dangerous backfeed. Have a qualified electrician determine the correct transfer equipment and installation for your panel, and follow the generator manual for connection and operation.
4. Decide whether inverter power or a battery station fits
Inverter generators can specify low total harmonic distortion, a detail that can help when choosing power for sensitive electronics. The PowerSmart listing claims under 3% THD; the Westinghouse tri-fuel listing specifies less than 5%. These are manufacturer-listed figures, not a guarantee that every appliance will be compatible. Check the device manufacturer’s power guidance if compatibility matters.
A battery station avoids engine fuel and exhaust while operating, but its stored energy and output limit what it can power and for how long. The Jackery’s 292Wh capacity and 300W rated output make it a portable option for small electronics, not a substitute for a high-output generator. Solar charging can help when compatible panels are available, but panels are optional and charging time depends on the setup.
5. Treat runtime and safe placement as planning details
Runtime claims usually depend on load and fuel. The Westinghouse tri-fuel model’s listing specifies up to 19 hours at 25% load on gasoline, not at full output. Compare each stated runtime at its stated load, and plan to refuel or recharge according to your likely use. The Oxseryn listing, for example, gives up to 14 hours at 25% load.
Fuel-powered generators produce carbon monoxide. Operate them outdoors and away from doors, windows, and vents, following the product manual and local safety guidance. A CO shutdown sensor is an added listed feature, not a replacement for safe placement or working household carbon monoxide alarms. Keep generators dry and follow the manufacturer’s instructions for grounding, refueling, and maintenance.

Frequently Asked Questions
What size generator do I need for home backup?
Add the running watts of the equipment you want to use and account for appliances that need extra starting power. Compare those totals with the generator’s running and peak ratings. For a connection to home circuits, ask an electrician to confirm your loads and transfer equipment.
Can I connect a portable generator to my home electrical panel?
Only with compatible transfer equipment installed and used according to local requirements and the manufacturer’s instructions. A transfer-switch-ready outlet does not mean the switch or installation is included. Never plug a generator into a household wall outlet to feed home wiring.
Is a dual-fuel or tri-fuel generator better?
Neither is automatically better for every home. A dual-fuel model uses gasoline and propane; a tri-fuel model adds natural gas. Choose based on fuel access, safe storage, connection needs, and the output listed for the fuel you expect to use.
Can an inverter generator power a refrigerator or furnace?
It depends on the appliance’s running and startup demands and the generator’s available output. Compare both ratings rather than relying on the word “inverter.” For a furnace or other hardwired equipment, confirm requirements and connection methods with a qualified electrician.
Can a portable power station replace a fuel generator?
A small power station can keep compatible low-wattage devices running, but capacity and output limit its use. The Jackery model listed here provides 292Wh and 300W rated output, so it is not intended for large appliances or whole-home backup. Estimate each device’s draw and the time you need it to run before choosing a battery unit.
Can I run a generator indoors or in a garage?
No. Fuel-powered generators create carbon monoxide and must be operated outdoors, away from openings and vents, as directed by the manual. A CO sensor does not make indoor or garage operation safe. Follow local guidance and maintain working household carbon monoxide alarms.
