GP5500E Portable Generator with Electric Start (Battery Included)

Power outages don't wait for convenient timing, and neither should you. The GP5500E electric start portable generator is built for reliable backup power at home or on the job site, and versatile enough for recreational use, tailgates, and everything in between. With the included battery and a simple rocker-switch start, you get hassle-free startups every time—no more wrestling with a pull cord when you need power most.

Built to Handle Rough and Rugged Conditions

This generator is engineered to keep working where lesser units quit. A hardened 1.25-in. steel-tube cradle adds serious strength and impact resistance, while the fold-down handle and never-go-flat wheels make it easy to maneuver across job sites, campgrounds, or your backyard. Covered outlets add an extra layer of protection from dust, moisture, and the elements, so you can count on it in tough environments.

Fuel-Efficient Power You Can Trust

At the heart of the GP5500E is a 298cc OHV engine with EFI (Electronic Fuel Injection) technology, engineered to optimize fuel efficiency and cut down on maintenance. Run it up to 10.5 hours at 50% load on a single tank, so you can power through a job, a storm, or a weekend outdoors without constant refueling.

Safety and peace of mind are built in. Onboard COsense® technology continuously monitors for hazardous carbon monoxide levels and automatically shuts the unit down if dangerous levels are detected. A low-oil shutdown feature protects your investment by powering down the engine before damage can occur, and the onboard hour meter makes it simple to track maintenance intervals—so you're never caught off guard.
