The catch
WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
Moving it sensibly means using the wheels and telescoping handle, since at 94.8 pounds it is not a one-person lift.
Side by side
WEN DF680iX vs Westinghouse iGen8200TFc: Backup planning gains a factory natural-gas option with Westinghouse
Quick verdict
Pick the WEN for its smaller dual-fuel setup, or the Westinghouse if natural gas is your route.
Before you buy
Why, and what it costs you
A running load of 4,400W on propane
Nominal margin is 100W for DF680iX and 1,540W for iGen8200TFc. A negative number means the continuous rating has been exceeded.
Where this comes from
The measured total running load is assumed to be 4400W on propane. Margin = fuel-specific running watts minus 4400. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
The catch
Westinghouse iGen8200TFc
Just because the outlet is 50A-shaped, do not assume the generator delivers 50A continuously at 240V.
WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
- Why pick it
- A dual-fuel inverter with a 30A twist-lock is what you need
- Gasoline and propane are the factory fuel choices you want
- The catch
- Moving it sensibly means using the wheels and telescoping handle, since at 94.8 pounds it is not a one-person lift.
Westinghouse iGen8200TFc
- Why pick it
- You need natural gas, or more starting capacity on propane
- You want gasoline, propane and natural gas as the factory fuel choices
- The catch
- Just because the outlet is 50A-shaped, do not assume the generator delivers 50A continuously at 240V.

Which one fits
Pick the situations that sound like you
A continuous propane load of 4,400W
On propane, the WEN gives 4500W running and the Westinghouse 5940W. A 4400W load is within both nominal ratings, though it leaves the WEN very little margin.

In practice
Differences you will notice
A running load of 4,400W on propane
Nominal margin is 100W for DF680iX and 1,540W for iGen8200TFc. A negative number means the continuous rating has been exceeded.
How we worked this out
The measured total running load is assumed to be 4400W on propane. Margin = fuel-specific running watts minus 4400. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
A total starting event of 6,100W
Measured against this separately specified total starting demand, DF680iX has -100W of published peak margin and iGen8200TFc has 1,280W.
How we worked this out
Take the combined load during one motor start as 6100W, counting the appliances already running. Subtract 6100 from the propane starting rating. That shows nothing about surge duration or whether the motor starts successfully.
A 30A 240V connection tops out at 7200W
On propane, neither generator reaches 7200W continuously. Their output equivalents are 18.75A for WEN and 24.75A for Westinghouse, before individual-leg constraints.
How we worked this out
30 × 240 = 7200W. 4500 ÷ 240 = 18.75A. 5940 ÷ 240 = 24.75A, taking power factor as 1.0.
Plug in your numbers
Can either generator run what you need?
This checks hard limits only. Personal preferences are left out of the math.
WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
Works with your numbersOn gasoline, it is rated for 5,100 running and 6,800 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
Westinghouse iGen8200TFc
Works with your numbersOn gasoline, it is rated for 6,600 running and 8,200 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
The estimate adds up the running watts of everything on at once, the biggest single startup surge and 15% headroom. Check each appliance label before you rely on it. Never run a fuel-burning generator indoors, in a garage or near doors, windows or vents.
Option A
WEN, DF680iX
DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
Gasoline gives 5,100 running watts and 6,800 starting watts, and propane is the other fuel option.

Spec by spec
Where they really differ
| Spec | WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator | Westinghouse iGen8200TFc | In practice |
|---|---|---|---|
| Running and starting output on propane | 4,500W running / 6,000W starting | 5,940W running / 7,380W starting | Each of continuous load and brief starting demand has its own limit. |
| Factory fuel choices | Gasoline and propane | Gasoline, propane and natural gas | Use the output rating for the fuel you have on hand. |
| Starting system | Electric with recoil backup | Remote and electric with recoil backup | How easy it is to start is a separate matter from how the generator is carried. |
| Handling layout | Wheels and telescoping handle | 134.5lb wheeled enclosure | Look at the route out of storage and how it will get into a vehicle. |
| Connection panel | 120/240V L14-30R plus 120V TT-30R and two 5-20R sockets | 120/240V 14-50R plus 120V TT-30R and duplex 5-20R | Match the exact receptacle, breaker and cord to the system you intend. |
| Gasoline tank | 2.9 gallons | 3.9 gallons | Runtime at your load cannot be worked out from tank size alone. |
| Power regulation | Inverter, Under 1.2% at full load | Inverter, Under 3% | Check waveform requirements specific to the load. |
Trade-offs
What each pick costs you
With WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
- With 5,100 gasoline running watts and 30-amp outlets, it suits an RV or particular home circuits, but not a 50-amp whole-home load. Natural gas and remote start are also missing.
With Westinghouse iGen8200TFc
- Propane and natural gas both rate lower than gasoline. Treat running load and motor starting demand as separate questions.
Change of plan
When the answer changes
A dual-fuel inverter with a 30A twist-lock is what you need
Go with WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator. On propane, the WEN gives 4500W running and the Westinghouse 5940W. A 4400W load is within both nominal ratings, though it leaves the WEN very little margin.
You need natural gas, or more starting capacity on propane
Go with Westinghouse iGen8200TFc. Factory natural-gas operation and remote start come with the iGen8200TFc. The DF680iX runs on gasoline or propane only and has push-button electric start.

Look at how each is used day to day
Factory natural-gas operation and remote start come with the iGen8200TFc. The DF680iX runs on gasoline or propane only and has push-button electric start.
Get the connection and installation right
For 240V, the WEN has an L14-30R and the Westinghouse a 14-50R. Confirm the exact input cable and an electrician-approved installation before reading the larger socket as extra capacity.
What this page can’t tell you
- Treat these as calculations from specifications. No generator or motor-start measurements back them.
- Usable output can fall because of altitude, temperature, fuel supply and the limit on an individual 120V leg.
- Even with CO shutoff, a generator is not safe indoors, in a garage or under an enclosed shelter.
