TruePower™ Technology: Clean and Safe Energy
One of the most important features of the GP3300i is Generac’s TruePower Technology, which delivers stable and clean power with less than 3% total harmonic distortion. This makes it safe for sensitive electronics, including laptops, smartphones, tablets, GPS units, and cameras.
Benefits of TruePower:
- Safe for sensitive electronics
- Smooth operation for tools and appliances
- Reduces the risk of power surges or equipment damage
Whether you’re charging devices or running tools on the go, you’ll appreciate the consistent voltage and frequency this inverter generator provides.
PowerRush™ Advanced Technology: Extra Starting Capacity
The PowerRush Advanced Technology in the GP3300i gives you over 50% more starting power. This additional surge capacity is especially useful for motor-driven appliances and tools that require more power at startup, such as:
- Power drills
- Circular saws
- Portable AC units
- Refrigerators
- Water pumps
By temporarily increasing power output on demand, PowerRush enables the generator to handle high-starting current loads with ease—making this inverter generator much more versatile than many others in its class.
Economy Mode: Maximizing Fuel Efficiency
The Economy Mode in the GP3300i automatically adjusts engine speeds based on the connected load. This reduces fuel consumption, noise levels, and wear and tear on the engine, which translates to:
- Longer runtime per tank
- Lower fuel costs
- Extended generator lifespan
In addition, the eco-mode operation helps keep sound levels to a minimum, making it suitable for quiet environments like campgrounds or residential neighborhoods.
COsense® Technology: Carbon Monoxide Monitoring
Safety is a key concern when operating any generator, and the GP3300i is equipped with COsense® Technology, which continuously monitors carbon monoxide levels in the surrounding air.
COsense Features:
- Automatic shutdown if dangerous CO levels are detected
- Real-time alerts via LED indicator
- Improved safety in enclosed or semi-enclosed areas
This feature adds an important layer of protection, especially during outdoor recreation or when using the generator near living areas.
Smart Controls and Indicators for Easy Monitoring
This generator is user-friendly and built for simple operation. With intuitive LED status lights, users can quickly determine whether the generator is:
- Ready to operate
- Experiencing overload
- Low on oil
The LED control panel improves usability, especially in low-light conditions, making it ideal for emergency use at night or in poor weather.
Multiple Output Options for Versatile Use
Despite its compact size, the GP3300i features a variety of output ports to cover multiple needs simultaneously:
Output Ports:
- 2x 120V AC outlets
- 2x USB ports
- 1x DC outlet (12V)
- Parallel ports for combining two GP3300i units for increased output
This output configuration makes it perfect for:
- Charging phones and tablets
- Powering TVs and entertainment systems
- Running power tools
- Operating small kitchen appliances
The parallel-ready design gives you flexibility to double your power output by connecting another compatible Generac inverter generator using a parallel kit (sold separately).
Lightweight Build and Portability
Weighing only 59.5 pounds, the GP3300i is ideal for solo transport. It includes a built-in ergonomic handle that balances weight distribution, allowing one person to carry it easily without straining.
Whether you’re moving it from the garage to the backyard or from your vehicle to the campsite, this generator is ready to go where you go.
