Powerful Portable Performance

With PowerRush Advanced Technology, the GP6500 delivers up to 40% more starting capacity, allowing it to start heavy loads—such as sump pumps, refrigerator compressors, and large motors—more efficiently while maintaining rated running power of 6,500 watts. Its 8,125 starting watt capacity ensures you won’t overload the system when devices draw sudden surges.

Its robust 389 cc Generac OHV engine and steel fuel tank with built-in gauge allow it to run up to 10.5 hours at half load, ensuring reliable operation for backup or recreational power needs.


Smart Protection with COsense Sensor

Safety features are robust, including COsense technology, which continuously monitors carbon monoxide levels and automatically shuts down the generator if dangerous levels accumulate. This critical function enhances safe use around homes, RVs, or partially enclosed areas.

Combined with low-oil level auto-shutdown, the GP6500 safeguards the engine from damage if oil levels drop too low, contributing to long-term reliability.


Built for Rugged Durability and Ease of Transport

The GP6500 is built to endure tough conditions with features such as a 1.25-inch steel-tube cradle and never-flat wheels, which offer excellent portability across uneven terrain. The fold-down handle enables compact storage.

Outlets are protected with durable covered ports, shielding them from dust and moisture. The control panel includes GFCI outlets and a twist-lock L14‑30R outlet for transfer switch compatibility.


Maintenance Made Easy

An hour meter tracks accumulated run time to remind operators when to perform oil changes, filter checks, or service tasks. Low-oil shutdown automatically protects the engine if oil drops below safe levels. These features simplify upkeep and help extend engine life.

Included accessories such as oil, funnel, wheel kit, and owner’s manual mean minimal assembly—and immediate readiness—for first-time users.
