The Westinghouse iGen4500 5000W Inverter is the best all-around pick for buyers who want a gas inverter with 3,900 rated watts, remote start and an RV-ready 30A outlet. For smaller loads, the iGen1500c and iGen2550c are lighter, while the 12000W models suit buyers planning larger backup loads and multiple fuel options.

Choose by running watts, fuel access and outlets before comparing convenience features. Peak watts describe short startup capacity, while running watts are the better number for loads you need to keep powered.

If you're sizing a backup system, start with how many watts you need to run a house. RV owners can compare outlet and load needs in our 30 amp RV generator size guide, and our portable generator guide covers other brands and formats.

How we chose Westinghouse inverter generators

We compared the eight eligible models by running output, fuel choices, outlet types, portability features and stated runtime. Our score weighs specs, features and buyer feedback against what you're shopping for.

The models cover compact 120V use, RV setups, and larger backup needs. The right fit depends on the loads you plan to run at the same time, not the peak watt number alone.

We left out the iGen4500DF because the CPSC recall covered units made from October through December 2019. The separate 2017 recall covered the older iGen2500 and iPro2500, not the iGen2550 in this guide.

The generator can parallel with a compatible Westinghouse inverter, with cables sold separately. A CO sensor and overload protection are also included.

Choose it if you want a modest output increase over the iGen2550c and can handle the extra weight. For light loads and easier carrying, the 30.1 lb iGen1500c is smaller.

How should you choose a Westinghouse inverter generator?

Start with the appliances you want to run at once, then compare their running watts and startup needs with the generator's running output. Keep a margin for motor starting and avoid treating peak watts as continuous capacity.

For a smaller setup, the iGen1500c or iGen2550c can suit a limited load list. For higher household needs, the 8200W, 10000W and 12000W models offer more output, but fuel type changes the running watts on dual- and tri-fuel models.

Our guide to starting watts vs running watts explains why both numbers matter. If your plan centers on cooling or food storage, also see what size generator you need for a refrigerator.

Is a dual-fuel or tri-fuel Westinghouse inverter better?

A dual-fuel model runs on gasoline and propane, while a tri-fuel model adds natural gas. That extra choice can be useful if you already have a suitable fuel supply, but each model's running output can change with the fuel.

The iGen12000DFc delivers 9,000 running watts on gasoline and 8,100 on propane. The iGen12000TFc also runs on natural gas, rated at 7,200 running watts, so choose based on fuel access and the actual load you need to support.

If you are weighing stored fuel and runtime, our propane vs gas generator guide compares practical fuel tradeoffs. Follow the generator manual and fuel equipment instructions for setup and operation.

What safety checks matter with a portable generator?

Use a portable generator outdoors, far from doors, windows and vents, and follow the manufacturer's manual and CPSC safety guidance. A CO sensor is a feature, not a reason to run a generator indoors or near openings.

The iGen2550c, iGen1500c, iGen2800c and larger models in this roundup list CO sensors. Read the manual for placement and operation details, and review our guide on how far a generator should be from the house.

For home wiring connections, use equipment designed for the job and consult a licensed electrician. A transfer-switch-ready outlet does not make improvised wiring safe.

Which Westinghouse inverter generator should you pick?

Pick the iGen4500 5000W Inverter for a mix of RV connections, remote start and 3,900 rated watts. Choose the iGen1500c or iGen2550c for lighter loads, the 8200W tri-fuel model for three fuel choices at mid-range output, or a 12000W unit when your load plan calls for higher output.

Before buying, match running watts, startup needs, fuel availability, outlet type and the weight you can manage. For a brand comparison, read Westinghouse vs DuroMax generators; for broader selection advice, use how to choose a generator.
