Editor's Choice - Westinghouse WGen9500DF

Using propane instead can save you a lot of money and give you longer total runtime (combining gas and propane). That's why the Westinghouse Wgen9500DF is our favorite 10000-watt generator. It's one of the most reliable dual fuel generators in this power range currently available in the US.
