GP18000E 18,000‑Watt Portable Gas Generator for sale

The Generac GP18000E (GP18000EFI) Portable Generator is a heavy‑duty, high‑wattage unit designed for emergency home backup, construction sites, rental fleets, and demanding industrial or commercial applications. With 18,000 running watts and 22,500 starting watts, it can power large tools, air compressors, pumps, welders, and key household loads during outages. An 816cc EFI (Electronic Fuel Injection) engine improves fuel efficiency, cold starting, and throttle response compared with traditional carbureted units, providing up to around 9 hours of runtime at 50% load from the large 14.2‑gallon fuel tank.

TruePower Technology delivers cleaner power with less than about 5% total harmonic distortion, making it suitable for many sensitive electronics and modern appliances when used as directed. Integrated COsense carbon monoxide detection monitors exhaust conditions and can shut down the generator if hazardous CO levels are detected, adding an extra layer of safety on job sites and around the home. A hardened steel tube frame, large never‑flat wheels, and folding locking handles make this powerful generator easier to transport.
