DuroMax

What DuroMax does

DuroMax Power Equipment, founded in 2003 and headquartered in Ontario, California, manufactures portable generators and outdoor power equipment for the U.S. consumer and small-business segments. The company's core catalog spans portable generators from 2,300W to 28,000W, organized into HX (dual fuel), HXT (tri-fuel), iH (dual fuel inverter), and iHT (tri-fuel inverter) series, with select high-capacity models featuring Electronic Fuel Injection (EFI), digital inverter output under 3% total harmonic distortion (THD), all-copper windings, and CO Alert carbon monoxide shutoff. Complementary products include OEM engines (7-35 HP), semi-trash and high-pressure water pumps, and a LiFePO4 portable power station, alongside a DuroStar budget sub-brand. Generators are designed by the Ontario engineering team and manufactured overseas to specification.

The business model is direct-to-consumer hardware sales with multi-channel distribution. DuroMax sells through its own e-commerce site (duromaxpower.com), the Amazon marketplace, Home Depot, and Lowe's, supplemented by an authorized dealer and installer network with active 'Become-a-Dealer' and 'Become-an-Installer' recruitment programs. Pricing spans roughly $629 entry-level units to $9,499 premium 28,000W tri-fuel inverter models, with free shipping on orders over $199 and a separate accessories revenue stream (Reliance transfer switches, AirGo soft starters and EV chargers, GenInterlock kits, Flame King propane tanks, Lucas Oil consumables, GenTent weather covers).

Revenue mechanics are entirely transactional: one-time hardware purchases with no subscription, service-contract, or recurring revenue layer disclosed. Primary customer segments are homeowners seeking whole-home backup power during outages, contractors and jobsite professionals requiring portable heavy-duty power, food truck operators, and RV and outdoor recreation users. The company operates only in the United States, with an engineering office in Ontario, California, a Houston, Texas retail showroom, and distribution through nationwide retail partners.
