- Start by calculating your wattage needs. Add up the running watts of everything you want to power simultaneously, then check that the generator's running watts exceed that total. Our guide on how to size a generator for your home walks you through this process step by step.
- Decide between inverter and conventional technology. If you need to power laptops, medical devices, or other sensitive electronics, choose an inverter model (iGen series) with 3% THD or the WGen11500TFc with its sub-5% THD. If you are only powering tools, appliances, and lights, conventional models give you more watts per dollar.
- Choose your fuel type carefully. Dual-fuel (gasoline and propane) covers most buyers. Tri-fuel adds natural gas, which is ideal if you have a home gas line and want unlimited runtime during outages. EFI models eliminate carburetor maintenance and start more reliably after storage.
- Consider noise level if you live in a neighborhood. Inverter generators run at 52 to 60 dBA, which is comparable to normal conversation. Conventional models range from 68 to 74 dBA, which is closer to a vacuum cleaner. Check local noise ordinances before buying.
- Look at the outlet configuration. If you plan to connect to a whole-house transfer switch, you need a 50A (14-50R) outlet, which is only available on models with 8,200+ peak watts. For RV use, look for a TT-30R outlet. For job sites, duplex 120V outlets are most versatile.
- Factor in runtime and tank size. A larger tank means fewer refueling interruptions during an outage. The WGen10500TFc and WGen11500TFc lead with 9.5-gallon tanks and 19-hour runtimes. For camping, the iGen2800DFc's 38-hour propane runtime is hard to beat.
- Do not overlook the variant families. Westinghouse offers many models in multiple configurations. Before buying, check whether a variant with a CO sensor, different fuel type, or EFI might better suit your needs at a similar or lower price.
- Always verify CARB compliance if you live in California or states that follow California emissions standards. Models marked EPA-only cannot be sold in those states. Most mid-range Westinghouse models are CARB compliant, but the tri-fuel and some high-wattage models are not.
Important Safety Notes
⚠️ WARNING: NEVER run or NEVER operate a generator indoors, in a garage, in a basement, or in any enclosed or partially enclosed space. Generators produce carbon monoxide, an odorless and deadly gas. Always use your generator outdoors only, positioned at least 20 feet away from windows, doors, and vents.
⚠️ WARNING: While many Westinghouse models on this list include CO sensors with automatic shutdown, these are a backup safety measure and not a substitute for proper placement. Always position the generator outdoors only with the exhaust pointing away from any occupied structure.
⚠️ WARNING: NEVER connect or NEVER plug a generator directly into a wall outlet or your home's electrical panel. This is called backfeeding and can electrocute utility workers and damage your equipment. Always use a properly installed transfer switch to connect a generator to your home's electrical system. A licensed electrician should install the transfer switch.
⚠️ WARNING: Store all fuel in approved containers designed for that specific fuel type, and keep fuel away from living areas, the generator itself while it is running, and any ignition sources. Allow the generator to cool completely before refueling.
⚠️ WARNING: Before starting your generator, check the oil level and ensure all connections are secure. Never operate a generator in wet conditions without proper cover, and never touch the generator with wet hands.

FAQ
What is the difference between Westinghouse DF, DFc, TFc, and EFI models?
DF stands for Dual Fuel, meaning the generator runs on gasoline and propane. DFc adds a carbon monoxide sensor with automatic shutdown to the dual-fuel platform. TFc means Tri-Fuel with a CO sensor, adding natural gas as a third fuel option alongside gasoline and propane. EFI indicates Electronic Fuel Injection, which replaces the traditional carburetor for easier starting, better fuel efficiency, and reduced maintenance. These suffixes can be combined, so a WGen9500TFc EFI is a tri-fuel model with both a CO sensor and electronic fuel injection. Models without any suffix (like WGen9500c) are typically gasoline-only with a basic feature set.
Can I use a Westinghouse conventional generator to power sensitive electronics like computers?
It depends on the model's THD (Total Harmonic Distortion). Most conventional Westinghouse generators produce 23% THD, which is too high for sensitive electronics and can cause damage over time. The WGen11500TFc and its dual-fuel variant produce under 5% THD, which is much safer. For the cleanest power, the iGen8200TFc, iGen5000DF, and iGen2800DFc inverter generators produce 3% THD or less. If you need to power computers, medical equipment, or high-end AV gear, choose a low-THD model. For more on this topic, read our guide on why some generators kill appliances and others do not.
How long can I run a Westinghouse generator on natural gas?
Tri-fuel models like the WGen11500TFc, iGen8200TFc, and WGen10500TFc can connect to a home natural gas line for a theoretically unlimited fuel supply. Unlike gasoline or propane tanks that need refilling, a natural gas connection provides continuous fuel as long as the utility supply is active. However, you should still follow the manufacturer's recommended maintenance intervals, including oil changes every 100 to 200 hours of operation. The engine needs periodic rest and servicing during extended outages.
Are Westinghouse generators transfer switch ready?
Yes, every generator on this list includes at least one transfer-switch-compatible outlet. Models with a 50A (14-50R) outlet, such as the WGen11500TFc, WGen10500TFc, WGen9500DF, and iGen8200TFc, can connect to larger whole-house transfer switches. Models with a 30A (L14-30R) or L5-30R outlet work with smaller subpanel transfer switches. Always use a properly installed transfer switch and NEVER connect a generator directly to your home's wiring, as this creates a dangerous backfeed condition.
Which Westinghouse generator is best for an RV?
Several models on this list include a dedicated TT-30R RV outlet for direct plug-and-play connection. The iGen2800DFc is the best choice for small RVs and pop-up campers thanks to its 45-pound weight and 52 dBA noise level. The WGen5300DFc and WGen6000DFc EFI are better for larger RVs with 15,000 BTU air conditioners, offering 5,300 and 6,000 running watts respectively. The iGen5000DF is an excellent middle ground, providing inverter-clean power at 52 dBA with enough wattage for most RV setups. For RV use, you generally need 3,000 to 5,000 running watts depending on your AC unit size.
Do Westinghouse generators come with a warranty?
Every Westinghouse generator on this list includes a 3-year limited warranty covering both residential and commercial use. Westinghouse also provides lifetime technical support, which is a notable benefit that many competitors do not offer. Keep your purchase receipt and register your generator online to ensure full warranty coverage. The warranty covers defects in materials and workmanship but does not cover damage from misuse, lack of maintenance, or normal wear.
How do Westinghouse generators compare to Honda or Champion?
Westinghouse generally offers more features per dollar than Honda, including multi-fuel capability, remote start, CO sensors, and EFI options at significantly lower price points. Honda is known for exceptional build quality, fuel efficiency, and resale value but charges a substantial premium for those advantages. Compared to Champion, Westinghouse tends to have a broader selection of tri-fuel and EFI models, while Champion competes aggressively on price and offers some unique features like dual-fuel inverters at lower price points. Westinghouse sits in the middle, offering a strong balance of technology, features, and value. For a broader comparison across brands, check out our guide on the best portable generators.
