The catch
WEN DF480iX
Only 120V is available, and a plug adapter will not produce 240V.
Side by side
If you need 240V or more motor-start allowance, the DF680iX is the one.
Before you buy
Nominal margin is 300W for DF480iX and 1,200W for DF680iX. A negative number means the continuous rating has been exceeded.
Where this comes from
The measured total running load is assumed to be 3300W on propane. Margin = fuel-specific running watts minus 3300. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
The catch
Only 120V is available, and a plug adapter will not produce 240V.
The catch
Moving it sensibly means using the wheels and telescoping handle, since at 94.8 pounds it is not a one-person lift.

DF480iX and DF680iX go head to head on fuel-specific power, starting demand, voltage and connection limits, to help you choose a generator.
If you need 240V or more motor-start allowance, the DF680iX is the one.
Which one fits
Beyond a bigger peak number, the DF680iX has a voltage selector and an L14-30R that give a documented 120/240V path. The DF480iX is 120V only.
Running on propane, the DF680iX gains 900W of continuous capacity and 1680W of published starting capacity. A pump plan still has to rely on the measured or nameplate starting requirement.
Tank size is 2.9 gallons on the DF680iX and 1.9 gallons on the other. Half-load runtimes are published for different watt loads, so you should not read them as a fuel-efficiency comparison.
DF680iX can supply the voltage, and its 4500W propane rating is 660W over 3840W. DF480iX cannot provide 240V, even with its 4000W gasoline rating.
In practice
Nominal margin is 300W for DF480iX and 1,200W for DF680iX. A negative number means the continuous rating has been exceeded.
The measured total running load is assumed to be 3300W on propane. Margin = fuel-specific running watts minus 3300. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
Measured against this separately specified total starting demand, DF480iX has -680W of published peak margin and DF680iX has 1,000W.
Take the combined load during one motor start as 5000W, counting the appliances already running. Subtract 5000 from the propane starting rating. That shows nothing about surge duration or whether the motor starts successfully.
DF680iX can supply the voltage, and its 4500W propane rating is 660W over 3840W. DF480iX cannot provide 240V, even with its 4000W gasoline rating.
The assumed load is resistive, 240V and 16A, at power factor 1.0. 240 × 16 = 3840W. It does not certify compatibility with EV charging.
Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
On gasoline, it is rated for 4,000 running and 4,800 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
On 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.
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.

WEN, DF480iX
Wheels and electric start come with this 120V dual-fuel inverter. Running output is 4000W on gasoline and 3600W on propane, and it has four household sockets plus a TT-30R RV connection.

WEN, DF680iX
Gasoline gives 5,100 running watts and 6,800 starting watts, and propane is the other fuel option.
Spec by spec
| Spec | WEN DF480iX | WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator | In practice |
|---|---|---|---|
| Running and starting output on propane | 3,600W running / 4,320W starting | 4,500W running / 6,000W starting | Each of continuous load and brief starting demand has its own limit. |
| AC voltage | 120V only | 120/240V | An unsupported voltage cannot be created by an adapter. |
| Connection panel | 120V TT-30R plus four 5-20R sockets | 120/240V L14-30R plus 120V TT-30R and two 5-20R sockets | Match the exact receptacle, breaker and cord to the system you intend. |
| Gasoline tank | 1.9 gallons | 2.9 gallons | Runtime at your load cannot be worked out from tank size alone. |
Trade-offs
Change of plan
Go with WEN DF480iX. Beyond a bigger peak number, the DF680iX has a voltage selector and an L14-30R that give a documented 120/240V path. The DF480iX is 120V only.
Go with WEN DF680iX Quiet 6800-Watt Dual Fuel Inverter Generator. Running on propane, the DF680iX gains 900W of continuous capacity and 1680W of published starting capacity. A pump plan still has to rely on the measured or nameplate starting requirement.
Decision guide
The DF680iX is the choice when 240V or a bigger motor-start allowance is a requirement.
