Generac 8000W Electric Start Portable Generator

The Generac GP8000E Portable Generator with COsense® Technology is engineered to deliver robust and reliable power exactly when you need it. At its heart lies a powerful 437cc OHV engine that produces a steady 8,000 running watts and an impressive 10,000 peak surge capacity, ensuring you can confidently power heavy-duty equipment, multiple appliances, HVAC systems, and critical home circuits all at once.

Starting this generator is simple and dependable, thanks to its electric start system with included battery—no more manual pull-cords—plus a convenient recoil backup for redundancy. The integrated PowerRush™ advanced technology provides a 30% boost in starting power, enabling it to kick-start high-demand motors and compressors with ease, all while offering smooth, continuous operation under load.

A standout feature is the COsense® carbon monoxide detection system, which actively monitors exhaust gas levels and automatically shuts down the unit if elevated CO is detected—keeping your family or crew safer during operation. The engine is also safeguarded by a low-oil shutdown feature that prevents damage from insufficient lubrication.

Built tough for both jobsite and home environments, the GP8000E rides on durable, never-flat wheels and features a heavy-duty steel-tube frame with fold-down handles for easier maneuverability and compact storage. Fuel is stored in a capacious 8-gallon steel tank with an integrated gauge, offering hours of runtime at half load and minimizing refill frequency during extended use.

The full-featured control panel includes two 120V GFCI outlets, a 120/240V twist-lock outlet, and a 120V 30A RV-ready outlet, along with an hour meter to track engine maintenance intervals. Whether you're hosting events, powering a worksite, or keeping your home running through an outage, the GP8000E combines top-tier output, advanced starting support, safety systems, and rugged portability.
