The Generac iQ3500 is a portable inverter generator designed to deliver reliable power wherever you need it, from camping trips and tailgating to job sites and emergency backup. This generator features a durable yet lightweight design at 109 pounds, making it easy to transport while maintaining robust performance.
The iQ3500 produces 3,500 starting watts and 3,000 running watts of clean, stable power safe for sensitive electronics. PowerRush Advanced Technology delivers over 50% more starting capacity for powering motor-driven equipment and tools. The advanced inverter technology and fully enclosed design make this generator 40% quieter than comparable models, with selectable engine speeds to balance quiet operation with power output.
Electric start capability comes standard with included battery and the intuitive PowerDial integrates start, run, and stop functions into one simple control. The digital smart LCD displays wattage, runtime remaining, fuel level, and hour meter. Features include economy mode for reduced noise and fuel consumption, low-oil shutdown for engine protection, USB ports for charging devices, and five total power outlets including a 30A twist-lock outlet. The 2.6-gallon fuel tank provides up to 8.9 hours of runtime at 50% load.
This model includes COsense Technology, a carbon monoxide sensor that automatically shuts down the generator when hazardous CO levels are detected for enhanced safety. The generator is parallel-ready, allowing connection of two iQ3500 units for doubled power output (parallel kit sold separately). CARB compliant and EPA certified for use in all 50 states. Powered by a Generac OHV 212cc engine with electronic ignition.
