Generac GP3300i Portable Inverter Generator with COsense - 3300W
Description
The Generac GP3300i is a compact, powerful inverter generator built for anyone who needs clean, reliable power on the go - whether you're camping, tailgating, running RV essentials, or preparing for unexpected outages. Powered by advanced PowerRush technology, it delivers over 50% more starting capacity than its rated output, making it capable of handling motor-driven appliances and tools without breaking a sweat. TruePower technology ensures the electricity you get is clean and stable, making it safe for sensitive electronics like laptops, phones, and medical devices.
Built with safety at the forefront, the GP3300i features Generac's COsense technology - a system that continuously monitors carbon monoxide levels and automatically shuts the generator down if dangerous CO is detected, protecting everyone nearby. The lightweight, ergonomic design with a built-in handle makes it easy to transport, while Economy Mode and quiet inverter operation mean you can run it without disturbing your surroundings.

Manuals & Guides
FAQ
What is COsense technology and why does it matter?
COsense is Generac's carbon monoxide detection system built directly into the generator. It continuously monitors CO levels in the surrounding air. If dangerous concentrations are detected, it automatically shuts the generator off and triggers an alert - helping to prevent CO poisoning, which can be fatal. It's a critical safety feature, especially for anyone using the generator near tents, vehicles, or enclosed or semi-enclosed spaces.
What does PowerRush technology do?
PowerRush technology allows the GP3300i to temporarily deliver more than its rated running watts when a motor-driven device first starts up. Electric motors require a surge of power to get moving that can be 2-3x their running draw. PowerRush provides over 50% more starting capacity on demand, making it possible to start RV air conditioners, power tools, and other motor-driven appliances that a conventional 2,500W generator might struggle with.
Can I connect two GP3300i generators together for more power?
Yes - the GP3300i is parallel-ready. By connecting two units with a compatible parallel kit (sold separately), you can effectively double your power output. This is ideal for situations where you need more wattage than one unit provides, such as running a larger RV setup or multiple high-draw appliances simultaneously.
Is this generator safe to use for sensitive electronics?
Yes. The GP3300i uses TruePower inverter technology, which produces clean, stable electricity with low total harmonic distortion. This makes it safe to use with laptops, smartphones, TVs, CPAP machines, and other electronics that are sensitive to power fluctuations - unlike conventional generators, which can produce "dirty" power that may damage sensitive devices.
How long will it run on a full tank of fuel?
At 50% load, the GP3300i runs approximately 4.5 hours on its 1.06-gallon fuel tank. Using Economy Mode, which throttles the engine down during light loads, can extend runtime further. For longer events or overnight use, having an extra fuel supply on hand is recommended.
Does the GP3300i require assembly before use?
The generator arrives largely pre-assembled - you will need to add oil before the first use, as it ships dry. Refer to the included owner's manual for first-use oil fill instructions and startup procedures. No major mechanical assembly is required.
