Product Overview
From emergency home backup to DIY projects to the jobsite, the Generac GP18000EFI portable generator provides high wattage, dependable portable power. Equipped with an 816cc engine with Electronic Fuel Injection, the GP18000EFI delivers power efficiently, providing up to 9 hours of runtime at 50% load. TruePower™ Technology safely powers sensitive electronics, appliances and tools while onboard COsense® Technology provides powerful protection against hazardous carbon monoxide. This model is CARB approved.
The GP18000EFI also features electric start (battery included), low-oil shutdown protection, circuit breaker protected outlets and an hour meter with maintenance resets. The included never-flat wheel kit and available lifting eye accessory make transportation easy around the home or jobsite.
Refurbished units are clean condition and most look brand new. Many are unused returns that have never been fired up except during testing. If there has been prior use, it is very minimal. Our generators are manufacturer refurbished and ship directly from Generac. They come in the box with everything included. All units are fully tested for performance and guaranteed to work like new. They come with a one year manufacturer's warranty.
