Head-to-head
WEN DF480iX vs Westinghouse iGen5000DFc EFI: WEN adds propane headroom, Westinghouse adds EFI and remote starting
The short answer
Choose slightly higher propane running capacity or EFI and remote start.
Before you choose
The reasoning and the trade-offs
A 3,200W running load on propane
DF480iX has 400W of nominal margin and iGen5000DFc EFI has 300W. A negative number means the continuous rating is exceeded.
What this is based on
Assume a measured total running load of 3200W on propane. Margin = fuel-specific running watts minus 3200. Starting transients, altitude, temperature, power factor and per-leg limits are not included.
Main trade-off
Westinghouse iGen5000DFc EFI Dual Fuel Inverter
It is not a 240V transfer-switch generator.

Winner by situation
Start with what you need it to do
A 3,200W continuous propane load
WEN offers 3600W running on propane and Westinghouse 3500W. The 100W difference is small, while their starting ratings go the other way at 4320W and 4500W.

Moving the generator and starting it during an outage
Westinghouse adds EFI and remote start. WEN uses electric start with a recoil backup and fuel-shutoff procedure for the carburetor. Decide how the machine will be started and stored.

A full 30A 120V continuous load on propane requires 3600W
At 120V, a 30A resistive load is 3600W. WEN reaches that running rating on propane, while the Westinghouse 3500W rating is 100W short.

What matters in practice
The differences that matter
A 3,200W running load on propane
DF480iX has 400W of nominal margin and iGen5000DFc EFI has 300W. A negative number means the continuous rating is exceeded.
How we reached this conclusion
Assume a measured total running load of 3200W on propane. Margin = fuel-specific running watts minus 3200. Starting transients, altitude, temperature, power factor and per-leg limits are not included.
A 4,200W total starting event
Against this separately specified total starting demand, DF480iX has 120W and iGen5000DFc EFI has 300W of published peak margin.
How we reached this conclusion
Assume the combined load during one motor start is 4200W, including the already-running appliances. Subtract 4200 from the propane starting rating. This does not establish surge duration or successful motor starting.
A full propane-powered TT-30R load separates them narrowly
At 120V, a 30A resistive load is 3600W. WEN reaches that running rating on propane, while the Westinghouse 3500W rating is 100W short.
How we reached this conclusion
120 × 30 = 3600W. A full-rated continuous load leaves no allowance for an additional appliance or starting transient.

Will either generator cover the load?
The result checks hard limits only. Preferences stay out of the calculation.
WEN DF480iX
Fits these inputs4,000 running watts and 4,800 starting watts on gasoline. This load plan calls for 1,200 running and 2,900 starting watts with reserve.
Westinghouse iGen5000DFc EFI Dual Fuel Inverter
Fits these inputs3,900 running watts and 5,000 starting watts on gasoline. This load plan calls for 1,200 running and 2,900 starting watts with reserve.
The estimate adds simultaneous running watts, the largest single startup surge and 15% headroom. Confirm every appliance label before relying on it. Never run a fuel-burning generator indoors, in a garage or near doors, windows or vents.

Meaningful differences
What changes the fit
| What changes | WEN DF480iX | Westinghouse iGen5000DFc EFI Dual Fuel Inverter | Why it matters |
|---|---|---|---|
| Running and starting output on propane | 3,600W running / 4,320W starting | 3,500W running / 4,500W starting | Continuous load and brief starting demand have separate limits. |
| Starting system | Electric with recoil backup | Remote and electric with EFI | Starting convenience is separate from how the generator is carried. |
| Handling layout | Wheels and telescoping handle | 111lb wheeled enclosure | Check the route from storage and how it will enter a vehicle. |
| Connection panel | 120V TT-30R plus four 5-20R sockets | 120V TT-30R plus duplex 5-20R | The exact receptacle, breaker and cord must match the intended system. |
| Gasoline tank | 1.9 gallons | 3.2 gallons | Tank size alone does not establish runtime at your load. |
| Power regulation | Inverter, Under 1.2% at full load | Inverter, 3% or less | Check load-specific waveform requirements. |
What you give up
Every choice has a cost
If you choose WEN DF480iX
- Fuel ratings fall on propane or natural gas. Check running load and motor starting demand separately.
If you choose Westinghouse iGen5000DFc EFI Dual Fuel Inverter
- At 111 pounds it is portable by wheels, not comfortably liftable by one person.
Recommendation switch
The decision flips if...
You want 3600W on propane and four household sockets
Choose WEN DF480iX. WEN offers 3600W running on propane and Westinghouse 3500W. The 100W difference is small, while their starting ratings go the other way at 4320W and 4500W.
You want EFI and remote electric starting
Choose Westinghouse iGen5000DFc EFI Dual Fuel Inverter. Westinghouse adds EFI and remote start. WEN uses electric start with a recoil backup and fuel-shutoff procedure for the carburetor. Decide how the machine will be started and stored.

How to make the call
Build the load list on the chosen fuel
WEN offers 3600W running on propane and Westinghouse 3500W. The 100W difference is small, while their starting ratings go the other way at 4320W and 4500W.
Check the practical ownership difference
Westinghouse adds EFI and remote start. WEN uses electric start with a recoil backup and fuel-shutoff procedure for the carburetor. Decide how the machine will be started and stored.
Confirm the connection and installation
Both are 120V-only units with a TT-30R. A 240V transfer requirement rules out both before fuel tank or remote controls enter the decision.
What this comparison cannot tell you
- These are specification-based calculations, not measured generator or motor-start tests.
- Altitude, temperature, fuel supply and individual 120V leg limits can reduce usable output.
- CO shutoff does not make a generator safe indoors, in a garage or under an enclosed shelter.
