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 iGen5000DFc EFI: Westinghouse’s remote-start EFI setup stays at 120V, whereas WEN supplies 240V
Quick verdict
Take 240V and more propane headroom, or take the EFI remote-start 120V unit.
Before you buy
Why, and what it costs you
A running load of 3,800W on propane
Nominal margin is 700W for DF680iX and -300W for iGen5000DFc EFI. A negative number means the continuous rating has been exceeded.
Where this comes from
The measured total running load is assumed to be 3800W on propane. Margin = fuel-specific running watts minus 3800. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
The catch
Westinghouse iGen5000DFc EFI Dual Fuel Inverter
It cannot serve as a 240V transfer-switch generator.
WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator
- Why pick it
- You require 240V, or more than 3500W on propane
- 120/240V is the AC voltage 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 iGen5000DFc EFI Dual Fuel Inverter
- Why pick it
- Your 120V loads fit, and remote EFI starting counts
- 120V only is the AC voltage you want
- The catch
- It cannot serve as a 240V transfer-switch generator.

Which one fits
Pick the situations that sound like you
A continuous propane load of 3,800W
A 3800W plan fits within the WEN’s 4500W propane running rating. It does not fit the Westinghouse’s 3500W, even with its 4500W peak rating.

Moving the generator and starting it when the power is out
The DF680iX has a 240V L14-30R, whereas the iGen5000DFc EFI delivers 120V only. That makes the voltage of your power system a hard requirement.

In practice
Differences you will notice
A running load of 3,800W on propane
Nominal margin is 700W for DF680iX and -300W for iGen5000DFc EFI. A negative number means the continuous rating has been exceeded.
How we worked this out
The measured total running load is assumed to be 3800W on propane. Margin = fuel-specific running watts minus 3800. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
A total starting event of 5,200W
Measured against this separately specified total starting demand, DF680iX has 800W of published peak margin and iGen5000DFc EFI has -700W.
How we worked this out
Take the combined load during one motor start as 5200W, counting the appliances already running. Subtract 5200 from the propane starting rating. That shows nothing about surge duration or whether the motor starts successfully.
A 240V 15A heater needs the voltage as well as 3600W
WEN supports 240V and has 900W more than this 3600W resistive load on propane. Westinghouse cannot supply the required voltage.
How we worked this out
240 × 15 = 3600W at power factor 1.0. 4500 minus 3600 = 900W. Motor-start demand is not part of this example.
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 iGen5000DFc EFI Dual Fuel Inverter
Works with your numbersOn gasoline, it is rated for 3,900 running and 5,000 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.

Spec by spec
Where they really differ
| Spec | WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator | Westinghouse iGen5000DFc EFI Dual Fuel Inverter | In practice |
|---|---|---|---|
| Running and starting output on propane | 4,500W running / 6,000W starting | 3,500W running / 4,500W starting | Each of continuous load and brief starting demand has its own limit. |
| AC voltage | 120/240V | 120V only | An unsupported voltage cannot be created by an adapter. |
| Starting system | Electric with recoil backup | Remote and electric with EFI | How easy it is to start is a separate matter from how the generator is carried. |
| Handling layout | Wheels and telescoping handle | 111lb 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 | 120V TT-30R plus duplex 5-20R | Match the exact receptacle, breaker and cord to the system you intend. |
| Gasoline tank | 2.9 gallons | 3.2 gallons | Runtime at your load cannot be worked out from tank size alone. |
| Power regulation | Inverter, Under 1.2% at full load | Inverter, 3% or less | 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 iGen5000DFc EFI Dual Fuel Inverter
- It weighs 111 pounds, so it moves on wheels and is not something one person can lift comfortably.
Change of plan
When the answer changes
You need 240V output, or a continuous propane load above 3500W and up to 4500W
Go with WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator. DF680iX supports 240V and delivers 4500W continuously on propane. The iGen5000DFc EFI is 120V only and tops out at 3500W on propane. Check motor-start demand on its own.
Your 120V loads fit, and remote EFI starting counts
Go with Westinghouse iGen5000DFc EFI Dual Fuel Inverter. The DF680iX has a 240V L14-30R, whereas the iGen5000DFc EFI delivers 120V only. That makes the voltage of your power system a hard requirement.
Decision guide
How to decide
The pick is 240V with more propane headroom, or the EFI remote-start 120V unit.
Test the load plan against your fuel
A 3800W plan fits within the WEN’s 4500W propane running rating. It does not fit the Westinghouse’s 3500W, even with its 4500W peak rating.
What each unit means in daily use
The DF680iX has a 240V L14-30R, whereas the iGen5000DFc EFI delivers 120V only. That makes the voltage of your power system a hard requirement.
Check connection and install details
EFI and remote starting are on the Westinghouse. The WEN relies on conventional fuel-shutoff maintenance and electric start. Neither feature alters the voltage your load requires.
What this page can’t tell you
- These numbers are worked out from specifications and not from measured generator or motor-start testing.
- Reduced usable output is possible with altitude, temperature, fuel supply and individual 120V leg limits.
- Indoors, in a garage or under an enclosed shelter, a generator is unsafe whether or not it has CO shutoff.
