Main trade-off
WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
At 94.8 pounds, it needs its wheels and telescoping handle for practical movement and is not a one-person lift.
Head-to-head
WEN DF680iX vs Westinghouse iGen5000DFc EFI: WEN supplies 240V, Westinghouse’s remote-start EFI setup stays at 120V
The short answer
Choose 240V and more propane headroom or the EFI remote-start 120V unit.
Before you choose
The reasoning and the trade-offs
A 3,800W running load on propane
DF680iX has 700W 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 3800W on propane. Margin = fuel-specific running watts minus 3800. 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 3,800W continuous propane load
The WEN’s 4500W propane running rating clears a 3800W plan. The Westinghouse’s 3500W does not, even though its peak rating is 4500W.

- Depends
- Westinghouse iGen5000DFc EFI Dual Fuel Inverter
- Not suitable
Moving the generator and starting it during an outage
DF680iX supplies a 240V L14-30R. The iGen5000DFc EFI supplies 120V only, so the power system voltage is a hard requirement.

What matters in practice
The differences that matter
A 3,800W running load on propane
DF680iX has 700W 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 3800W on propane. Margin = fuel-specific running watts minus 3800. Starting transients, altitude, temperature, power factor and per-leg limits are not included.
A 5,200W total starting event
Against this separately specified total starting demand, DF680iX has 800W and iGen5000DFc EFI has -700W of published peak margin.
How we reached this conclusion
Assume the combined load during one motor start is 5200W, including the already-running appliances. Subtract 5200 from the propane starting rating. This does not establish surge duration or successful motor starting.
A 240V 15A heater needs both voltage and 3600W
WEN supports 240V and exceeds this 3600W resistive load by 900W on propane. Westinghouse cannot supply the required voltage.
How we reached this conclusion
240 × 15 = 3600W at power factor 1.0. 4500 minus 3600 = 900W. This example excludes motor-start demand.

WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
Fits these inputs5,100 running watts and 6,800 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 DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator | Westinghouse iGen5000DFc EFI Dual Fuel Inverter | Why it matters |
|---|---|---|---|
| Running and starting output on propane | 4,500W running / 6,000W starting | 3,500W running / 4,500W starting | Continuous load and brief starting demand have separate limits. |
| AC voltage | 120/240V | 120V only | An adapter does not create an unsupported voltage. |
| 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 | 120/240V L14-30R plus 120V TT-30R and two 5-20R sockets | 120V TT-30R plus duplex 5-20R | The exact receptacle, breaker and cord must match the intended system. |
| Gasoline tank | 2.9 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 DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
- Its 5,100 gasoline running watts and 30-amp outlets fit an RV or selected home circuits, not a 50-amp whole-home load. It also lacks natural gas and remote start.
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 need 240V output or a propane continuous load above 3500W and within 4500W
Choose WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator. DF680iX supports 240V and supplies 4500W continuously on propane. The iGen5000DFc EFI is 120V only and stops at 3500W on propane. Check motor-start demand separately.
Your 120V loads fit and remote EFI starting matters
Choose Westinghouse iGen5000DFc EFI Dual Fuel Inverter. DF680iX supplies a 240V L14-30R. The iGen5000DFc EFI supplies 120V only, so the power system voltage is a hard requirement.
What matters in practice
How to make the call
Build the load list on the chosen fuel
The WEN’s 4500W propane running rating clears a 3800W plan. The Westinghouse’s 3500W does not, even though its peak rating is 4500W.
Check the practical ownership difference
DF680iX supplies a 240V L14-30R. The iGen5000DFc EFI supplies 120V only, so the power system voltage is a hard requirement.
Confirm the connection and installation
The Westinghouse has EFI and remote starting. WEN has conventional fuel-shutoff maintenance and electric start. Neither feature changes the load’s voltage requirement.
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.
