Generac 8945 iQ5200DF 3900W Electric Start Dual Fuel Portable Inverter Generator w/COsense Features:
Generac iQ5200DF (Model 8945) – 3900W Dual-Fuel Electric Start Portable Inverter Generator
The Generac iQ5200DF (Model 8945) represents the next generation of quiet, efficient, and versatile inverter power. Engineered to deliver reliable, clean energy for recreation, home backup, and professional work, this dual-fuel inverter generator runs on either gasoline or propane (LP), giving users ultimate flexibility and convenience.
With 3,900 running watts and 5,200 starting watts on gasoline (3,500 / 4,700 W on propane), the iQ5200DF easily powers appliances, tools, and sensitive electronics. It produces less than 3% total harmonic distortion (THD), ensuring safe operation for laptops, TVs, and communication devices. A fully enclosed acoustic case keeps operation whisper-quiet — perfect for RV parks, campsites, or residential neighborhoods — while Economy Mode automatically adjusts engine speed to match power demand, improving fuel efficiency and runtime.
Starting is effortless thanks to the push-button electric start with auto-choke (battery included). The intuitive Intelligent LED Display provides real-time feedback on wattage, fuel levels, and run time, while COsense® Technology continuously monitors carbon monoxide and shuts down the generator if unsafe levels are detected.
The iQ5200DF’s rugged yet portable design includes a durable outer enclosure, covered outlets, and integrated USB-A and USB-C charging ports for mobile devices. With up to 15 hours of runtime at 25% load (gasoline) or 20 hours on a 20 lb LP tank, it’s ready to keep you powered for long stretches — whether at work, on the road, or off the grid.
