The catch
Generac iQ3500 Portable Inverter Generator
The 7723-2 package chosen here is the 49-state version, so check local availability and emissions rules.
Side by side
Generac 7723 vs Westinghouse iGen5000DFc EFI: Westinghouse brings propane and extra headroom for larger RV loads
Quick verdict
Larger RV and outage loads suit Westinghouse, which has dual fuel and 3,900 gasoline running watts. Generac is the simpler premium gasoline inverter, a good fit if its display and established platform matter more to you.
Before you buy
Why, and what it costs you
Where these two really part ways
Generac iQ3500 Portable Inverter Generator is the better match for “Last all night with no refueling stop”. Westinghouse iGen5000DFc EFI Dual Fuel Inverter is the better match for “Power a sump pump through an outage” and “Power a window air conditioner”.
Where this comes from
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
The catch
Westinghouse iGen5000DFc EFI Dual Fuel Inverter
It cannot serve as a 240V transfer-switch generator.

What this page compares
Generac 7723 and Westinghouse iGen5000DFc EFI compared on running and starting output, fuel and voltage, power quality and handling.
This one comes down to running and starting output and fuel and voltage first, then to the limits of your own setup.

Fire it up from indoors before heading out
Generac iQ3500 Portable Inverter Generator lists “3,000 running W. 3,500 starting W on gasoline” for running and starting output, while Westinghouse iGen5000DFc EFI Dual Fuel Inverter lists “3,900 running W. 5,000 starting W on gasoline”. Extra published output only helps when your room, surface or workload needs the headroom. On its own, it does not prove better results.

How we worked this out
This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.
These needs do not split the pair
Both meet the same 3 of the 3 needs this comparison is built around, so the choice comes down to “running and starting output” and “fuel and voltage”.
How we worked this out
Both products are checked against the same needs. The first verified differences still standing are named here.
Models that handle “Power a refrigerator and the essential lights” and “Keep laptops and sensitive electronics powered”
8 of the 24 generator sets checked handle both “Power a refrigerator and the essential lights” and “Keep laptops and sensitive electronics powered”. Both make the cut.
How we worked this out
You can reproduce the count by filtering the current category for models with a strong or useful fit on both needs.
Plug in your numbers
Can either generator run what you need?
This checks hard limits only. Personal preferences are left out of the math.
Generac iQ3500 Portable Inverter Generator
Works with your numbersOn gasoline, it is rated for 3,000 running and 3,500 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.

Trade-offs
What each pick costs you
With Generac iQ3500 Portable Inverter Generator
- Propane operation and 240V output are both 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.
Decision guide
How to decide
Westinghouse is the better match for larger RV and outage loads, thanks to dual fuel and 3,900 gasoline running watts. Generac is the simpler premium gasoline inverter for anyone who values its display and established platform more.
The headline gap
Running watts run 900 higher on the Westinghouse.
What the specs change
Propane and remote start are exclusive to Westinghouse.
Shared features
Enclosed 120V inverters with electric start, both of them.
What this page can’t tell you
- Appliance reference loads are just estimates.
- Fuel-specific ratings can be far apart.
- Home wiring is the work of a qualified installer.
