PowerRush Technology delivers 50% More Starting Watts

Economy Mode for Quiet & Fuel-Efficient Operation

The Generac GP 3300 Generator with inverter technology can power outdoor activities from camping and RVing to tailgating and picnics or get-togethers. All the power you need without disturbing the neighbors or the wildlife.

GP 3300 inverter technology allows the generator engine to run at the speed appropriate for the connected load. Unlike regular portables that operate at a fixed speed, the engine speed varies for the power required. The 3300 Watt Generator economy mode saves fuel and reduces noise. Stand 20 feet away and have a conversation in a normal voice. The 1-gallon fuel tank provides up to 7 hours run time at 25% the rated load.

Economy mode on the Generac GP 3300 offers quieter operation and better fuel economy for loads without motors that don’t turn on and off. Turning economy mode off provides power for changing loads like RV air conditioners and refrigerators.
