Frequently asked questions
Is Westinghouse a good generator brand?
Yes — Westinghouse is a well-regarded value brand in the US portable and inverter generator market, popular for its dual-fuel WGen home-backup models and quiet iGen inverter series. Many models include a transfer-switch-ready outlet, remote start, and a 3-year warranty. For whole-home essentials backup on a budget, or a quiet unit for an RV, Westinghouse is a common recommendation.
Who makes Westinghouse generator engines?
Westinghouse portable generators are made by MWE Investments under license of the Westinghouse brand, using Westinghouse-branded OHV engines built for the line. The company handles its own US distribution, parts and warranty support.
What size Westinghouse generator do I need for my house?
For essential backup — fridge, furnace blower, a pump and lights — a WGen9500DF (9,500 running watts) is a popular whole-home-essentials choice, while a WGen12500 covers more, including a central AC in many homes. For quiet electronics use or an RV, an iGen inverter is better. Run your appliances through the sizing calculator to match the running watts to the right model.
