The Champion Power Equipment 100637 9000-Watt Electric Start Portable Generator with CO Shield® technology is designed to provide peace of mind and plenty of power when you need it.

Thanks to CO Shield® technology, you can be sure that you and your family are protected from the dangers of carbon monoxide. Our CO Shield® sensor tests itself automatically and lasts a minimum of a decade. If operated in inappropriate locations, the UL-listed sensor will alert and shut off the generator automatically before dangerous levels of carbon monoxide accumulate. This indicates the unit should be moved to an open-air environment with plenty of circulation.

This unit meets the ANSI/PGMA G300-2018 requirements to ensure the highest level of safety and performance. As a charter member of the PGMA (Portable Generator Manufacturers' Association), Champion helped develop this portable generator safety standard, including an important update addressing carbon monoxide safety.

The 459cc Champion engine produces 11,250 starting watts and 9000 running watts, and will run for 10 hours at 50% load when the 7.7-gallon fuel tank is full.

This unit can handle it all in an outage, plus the Volt Guard™ built-in surge protector prevents overloads.

With a noise level of 74 dBA from 23 feet, this unit has a 1.2 quart oil capacity.

Enjoy on/off push-button power with electric start, plus the Smart Charger keeps your included battery charged and ready while Cold Start Technology ensures a quick start in cold weather.

The Intelligauge monitors voltage, frequency and operating hours, while the foldaway handle and never flat tires make transport a cinch.
