About DuroMax
DuroMax Power Equipment is an American-owned power equipment company founded in 2003 and headquartered in Ontario, California. The company designs and services its products in the US, with manufacturing outsourced overseas, and its lineup centers on dual fuel and tri fuel portable generators alongside gasoline engines, water pumps, and pressure washers. DuroMax generators are sold direct from the company and through major retailers including Amazon, Walmart, and The Home Depot.
Independent reviewers have put DuroMax's dual-fuel generators through real-world testing rather than just spec-sheet comparisons — Bob Vila's hands-on review of the XP12000EH rated it 7.5 out of 10, calling out its power-per-dollar value, easy switching between gasoline and propane, keyed electric start, and built-in carbon monoxide detector. In our own review, the XP12000EH's all-metal-frame 457cc engine, 100 percent copper windings, and CO Alert automatic shutoff stood out as a heavy-duty option for large-home backup, and its dual-fuel design with MX2 Power Boost lets it double available 120V output for demanding appliances and RVs.
