DuroMax is an American company, founded in 2003 and headquartered in Ontario, California — though DuroMax generators are manufactured in China, which is where the confusion typically comes from.

DuroMax Power Equipment is the US-based parent company behind both the DuroMax and DuroStar generator brands. Design, engineering decisions, and servicing operations are run out of California. The generators themselves are built in Chinese factories, which is standard across most of this price tier — including competitors like Westinghouse. The more relevant question for buyers is component quality: DuroMax and DuroStar generators use OHV engines with cast iron cylinder sleeves and all-metal construction, which are verifiable specs regardless of where final assembly happens.

  • DuroMax Power Equipment was founded in 2003 in Ontario, California — a US-based company.
