Westinghouse 4000 Watt Dual Fuel Inverter and Its Siblings

Best for
Gaming setups and small RVs during outages

The Westinghouse 4000 Peak Watt Super Quiet dual fuel inverter, the Westinghouse iGen4000DF in its CO-sensor version, delivers 4,000 peak and 3,300 rated watts at less than 3% THD. It runs on gasoline or propane, starts by recoil, and comes with a wheel and telescoping handle kit so you can roll it out of the garage.

Outlets include a 5-20R 120V duplex household outlet, an RV-ready TT-30R 30 amp outlet and two USB ports. The LED data center rotates through fuel level, power output, remaining run time, voltage and lifetime hours, which helps you judge whether your PC and TV are pushing it too hard. It is rated as low as 52 dBA with up to 7 hours of run time; the features cite a 1.69-gallon tank while the description says 1.66 gallons. Economy Mode, automatic low oil shutdown, CO shutdown and parallel capability round it out, with 3-year limited coverage.

This is the sweet spot for a gaming household or a small trailer. It gives way to the 5000 if you want electric start and much longer runtime, and to the 12000 or 8200 if you need 240V home backup.

• 4,000 peak and 3,300 running watts, under 3% THD
• TT-30R, 5-20R duplex and two USB outlets
• CO shutdown and low oil shutdown
• Up to 7 hours at as low as 52 dBA

Best for
Longer runtimes with remote start

The Westinghouse 5000 Peak Watt Super Quiet is the iGen5000DF, with 5,000 peak and 3,900 rated watts at under 3% THD. The big upgrades over the 4000 are starting and runtime: it offers remote start with an included key fob plus electric and recoil start, and a 3.4-gallon tank that the listing rates for up to 18 hours.

It shares the same outlet layout (5-20R duplex, TT-30R and two USB), the LED data center, Economy Mode, a telescoping handle and a 52 dBA low noise figure. The listing does not mention a CO sensor for this model, unlike the 4000 and 2800. Pick the 5000 if you want to run a setup through the night without refueling; stick with the 4000 if CO shutdown matters more to you than runtime.

• 5,000 peak and 3,900 running watts
• Remote, electric and recoil start
• Up to 18 hours on 3.4 gallons

Best for
Lightweight camping and tailgating

The Westinghouse 2800 Peak Watt Super Quiet is the iGen2800DFc, the lightweight option at 45 pounds. On gasoline it makes 2,800 peak and 2,200 running watts; on propane, 2,520 peak and 1,980 running. It runs up to 12 hours at 25% load on a 1.1-gallon tank from a 98cc engine, and it is rated as quiet as 52 dBA.

It has a TT-30R 30A outlet and a 5-20R 20A duplex, a CO sensor, and less than 3% THD for phones, TVs and computers. The listing notes that for full 30A RV power you would parallel it with a compatible Westinghouse unit, with cables sold separately. This is the camping and tailgating pick for a console, a monitor and some lights. It gives way to the 4000 when you need more running watts.

Best for
Whole-home backup with clean power

The Westinghouse 12000 Peak Watt Dual Fuel iGen12000DFc brings inverter-quality power to whole-home backup: 12,000 peak and 9,000 running watts on gasoline, 11,000 and 8,100 on propane, all at 3% THD or less. A 457cc engine runs up to 19 hours at 25% load, and it can be as quiet as 64 dBA thanks to Eco Mode, insulation and mufflers.

It has a 14-50R 50A outlet and an L14-30R 30A twist lock, both transfer switch or interlock kit ready, plus a GFCI 5-20R duplex. Remote start key fob, battery, charger, propane regulator kit, oil, funnel and tool kit are included. Note that the features cite a 7.9-gallon tank while the specification table lists 9.8 gallons. Choose it to keep a whole house running, including your gaming room; for a single room it is more than you need.

• 9,000 running watts on gas, under 3% THD
• 50A and 30A transfer-switch-ready outlets
• Remote electric start with accessories included

Best for
Larger homes needing maximum output

The Westinghouse 14500 Peak Watt Dual Fuel is the WGen11500DFc home backup generator, the most powerful here: 14,500 peak and 11,500 running watts on gasoline, 13,500 and 10,500 on propane. A 550cc engine with a cast iron sleeve runs up to 19 hours on a 9.5-gallon tank or up to 7 hours on a 20 lb propane tank. It includes remote electric start, a fuel gauge, CO sensor, GFCI outlets and low oil shutdown.

Two caveats. Unlike the others, the title does not call it an inverter generator, and the description puts THD at less than 5% rather than 3%. The description also mentions natural gas even though the title says dual fuel, so confirm fuel options before buying. It suits larger homes that need raw output; for the cleanest power for electronics, the 12000 is the better choice.

Best for
Home backup with natural gas option

The Westinghouse 8200 Peak Watt Tri-Fuel Portable iGen8200TFc adds natural gas to gasoline and propane. Output is 8,200 peak and 6,600 running on gasoline, 7,380 and 5,940 on propane, and 6,560 and 5,280 on natural gas, all at under 3% THD. A 298cc engine runs up to 17 hours at 25% load on a 3.9-gallon tank, and it is around 60 dBA at 25% load.

It has a 14-50R 50A outlet that the listing says can run an air conditioner, refrigerator and sump pump at once, a TT-30R RV outlet and a GFCI 5-20R duplex, plus remote electric start and a CO sensor. It suits homes with a natural gas line and anyone who wants inverter power for home backup without stepping up to 12,000 watts. If you plan to keep a room cool during an outage, pairing it with a dual hose portable air conditioner is realistic within its running watts.
