Generac GP18000EFI Portable Generator, 816cc Engine, Electric Start, COsense

The Generac GP18000EFI is a high-wattage portable generator for emergency home backup, DIY projects and jobsite work, powered by an 816cc engine with electronic fuel injection. It runs up to 9 hours at 50% load, TruePower Technology holds total harmonic distortion below 5% for sensitive electronics and tools, and onboard COsense protects against hazardous carbon monoxide.

Electric start uses the included battery, low-oil pressure shutdown safeguards the engine automatically, and the outlets are protected by circuit breakers. An hour meter with maintenance resets keeps track of service intervals, and the large-capacity fuel tank carries an integrated fuel gauge.

A hardened 1 ¼ in steel tube cradle adds strength and durability, heavy-duty never-flat wheels come in the included wheel kit, and a lifting eye accessory can be added, so moving the generator around the home or jobsite is straightforward.
