Cummins Onan P9500DF EFI Dual-Fuel Portable Generator - EPA+CARB
Description
The Cummins Onan P9500DF EFI is the most powerful generator in the Onan portable lineup, built for serious home backup, jobsite power, and RV/camper use. It runs on either gasoline or propane (LPG) with a simple switch flip, giving you fuel flexibility when you need it most. The electronic fuel injection (EFI) system eliminates carburetor maintenance and allows operation at altitudes up to 13,000 ft (4,000 m) - no high-altitude carburetor kit required.
Safety is built in with an integrated carbon monoxide detector featuring automatic alarm and engine shutdown. A 6.6-gallon fuel tank delivers up to 14.4 hours of run time on gas or 10.8 hours on a 20 lb. propane tank at 25% load. Starting is effortless with a 99-foot remote starter, onboard push-button electric start, or pull cord backup - and it's all backed by the Cummins 24/7 global support network.

Why You'll Love It
The Cummins Onan P9500DF EFI is engineered for people who can't afford to be without power - whether that's a contractor on a remote jobsite, a homeowner prepping for outages, or an RV owner heading off-grid. The EFI engine is a genuine step up from carbureted portable generators: no winterizing the carb, no jetting for altitude, no hard starts after sitting in storage. Dual-fuel operation means you can stockpile propane for emergencies or run on pump gas when it's convenient. The integrated CO detector and auto-shutdown add a layer of safety that serious users demand. Trusted by the Cummins name - a brand with over a century of power generation heritage - and backed by a global service network, this generator is built to be there when everything else goes dark.

FAQ
What is the difference between peak watts and running watts?
Peak watts (9,500 W) is the surge power the generator can deliver for a brief moment when a motor or appliance first starts up - motors draw significantly more power at startup than during normal operation. Running watts (7,500 W) is the continuous power output the generator can sustain. When sizing your load, always use the running watt figure as your baseline and ensure your total connected load stays comfortably below 7,500 W.
Can I really switch between gasoline and propane while the generator is running?
The P9500DF is designed to switch between gasoline and propane (LPG) with the flip of a switch. For a smooth transition, it is generally recommended to let the engine run briefly on the new fuel source to stabilize before applying a heavy load. Consult the owner's manual for the manufacturer's specific switching procedure.
Why is EFI better than a carbureted generator?
Electronic fuel injection (EFI) automatically adjusts the fuel-air mixture based on conditions - altitude, temperature, and load - so the engine always runs optimally without manual tuning. This means no carburetor cleaning, no jetting changes for altitude, easier cold-weather starts, and better fuel efficiency. It is a meaningful upgrade for anyone who stores their generator seasonally or uses it at varying elevations.
Is this generator safe to use near my home or in a garage?
Like all gasoline-powered generators, this unit produces carbon monoxide (CO) and must NEVER be operated indoors, in a garage, or in any enclosed or partially enclosed space. The built-in CO detector and auto-shutdown are a safety feature designed to protect against CO buildup if the generator is inadvertently placed too close to a building or ventilation intake - but they are not a substitute for always operating the generator outdoors with exhaust directed away from any structure.
What is included with the generator - do I need to buy the propane tank separately?
The generator includes the unit itself and the wireless remote starter. Propane tanks are not included and must be purchased separately. A standard 20 lb. propane tank (the same size used for backyard grills) provides approximately 10.8 hours of runtime at 25% load.
