DuroStar generators are made by DuroMax Power Equipment, a California-based company founded in Ontario, CA in 2003 that also produces the DuroMax generator lineup under the same parent operation.

DuroMax Power Equipment designs and oversees both the DuroStar and DuroMax brands, which share near-identical engine specs, outlet layouts, and all-metal construction. The generators themselves are manufactured in China, while DuroMax Power Equipment handles design, engineering direction, and US-based servicing. DuroStar models are essentially the same machines as their DuroMax counterparts — differing mainly in color (DuroStar red vs. DuroMax blue) and price point.
