Clean and Stable Power for Sensitive Electronics

The Generac Portable Inverter Generator 2500i is equipped with TruePower™ Technology, which delivers extremely clean and stable electricity. That means you can operate sensitive electronics, such as smartphones, tablets, laptops, and medical devices, without worrying about voltage fluctuations that could damage your equipment.

Quiet Operation for Neighborhood-Friendly Power

Perfect for outdoor gatherings, camping trips, or any setting where noise could be disruptive, it ensures you enjoy your activities without disturbing neighbors or wildlife.

COSENSE® Technology for Powerful Carbon Monoxide Safety

Safety is a top priority, especially when using a generator outdoors. The Generac Portable Inverter Generator 2500i features COSENSE® Technology, which actively monitors for hazardous carbon monoxide levels. If dangerous CO levels are detected, the generator automatically stops or alerts you, protecting your health and safety during use.

Easy to Use with Intuitive Controls

Starting the generator is straightforward with integrated Off/Run/Choke knobs, simplifying the startup process. LED indicators keep you informed of essential operational statuses such as low oil, overload, and readiness, ensuring you stay aware of the generator’s condition.

Fuel Efficiency and Low Noise Levels

Economy Mode automatically adjusts engine speeds to optimize fuel consumption and minimize sound emissions. This feature extends runtime and allows for quieter operation, saving you money and creating a more harmonious outdoor experience.

Weighing just a few pounds for easy transport, the 2500i includes a built-in handle and fully-enclosed case for protection and convenience. Its covered outlets guard against environmental damage while providing all the essential connection points.

Multiple Power Outputs and Charging Options

The generator includes USB ports for charging mobile devices directly, along with standard outlets for larger appliances. Its parallel-ready feature lets you connect two GP2500i units for doubled power output, ideal for more demanding applications.
