Description
Zoom on the Cummins Onan P9500DF EFI
In a nutshell, the Cummins Onan P9500DF EFI is a portable generator mostly geared towards:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals in need of safely powering high-intensity work or lighting equipment
Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The Cummins Onan P9500DF EFI, equipped with dual-fuel technology and delivering 120/240V, ensures both power and versatility. Running on gasoline, it delivers a running wattage of 7,500W and a starting wattage of 9,500W. On propane, it provides 6,750 running watts and 8,550 starting watts.
At a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started via a standard recoil pull-rope starting mechanism, or a convenient and efficient electric starter (battery included). Additionally, the Onan P9500DF EFI features remote starting, offering users increased convenience (key fob included).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
The running time of the Onan P9500DF EFI, with its 6.6 gallons fuel capacity, can reach up to 14.4 hours on a full tank of gasoline (fuel consumption around 0.46 GPH). With propane, it can reach up to 10.8 hours (on a 20 lbs tank - propane consumption around 0.44 GPH).
Considering its high Total Harmonic Distortion (THD) of less than 23%, it is not recommended to rely on the Onan P9500DF EFI for powering sensitive electronic devices.
Outlets
The control panel features the following 5 AC outlets:
Moreover, it boasts 2 DC outlets: there's two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
Since it boasts a twist-lock L14-30R receptacle, the Onan P9500DF EFI is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
At L27.3 x W20.6 x H22.6 in, the traditional open frame structure of the Cummins Onan P9500DF EFI ensures stability while facilitating convenient maintenance access to components and promoting air cooling. The design is ideal for rough environments and demanding outdoor use.
While weighing 211.6 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
Features
Integrated into the control center of the Onan P9500DF EFI are a convenient meter, offering voltage, frequency, and lifetime hours readings, facilitating the monitoring of its status and activity.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
Apart from the standard documentation and an owner's manual to facilitate setup, the Cummins Onan P9500DF EFI features extra accessories: tool kit, propane hose, key fob, funnel and oil.
The Cummins Onan P9500DF EFI versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Cummins Onan P9500DF EFI compare to dual fuel generators of similar power (between 7000 and 8000 W).
- As its weight is 211.6 pounds, the Cummins Onan P9500DF EFI falls in the expected weight range of the dual fuel devices in the 7000-8000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
- With noise emissions rated as low as 74 dBA, this generator falls within the typical noise range expected for devices of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Champion 201175 with only 61 dBA.
- In terms of autonomy, the Onan P9500DF EFI offers up to 14.4 hours at a 25% load, placing it at the lower range within its type and power range. If you wish to prioritize autonomy, the DuroMax XP10000EH shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling up to 22 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. In fact, this generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 25% load is around 0.46 GPH. To prioritize fuel savings, we advise considering the DuroMax XP9500iH, which stands out for its gasoline efficiency, consuming just 0.34 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 7000-8000W dual fuel generators, the Cummins Onan P9500DF EFI is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

About Cummins
Cummins is a NYSE publicly traded, Fortune 500 corporation dealing in the power sector and heavy industry. Founded in 1919 in Columbus, IN, by William Glanton Irwin and Clessie Cummings, Cummins focused on the development of diesel engines. However, the company truly came to bloom only after the WWII, with the nationwide road expansion and went finally global in the 1960s, with its heavy-duty trucks. Cummins has, over the years, offered a wide variety of power solutions, from actual power plants to RV generators. Yet, the company has only recently dipped its foot into the portable generator market. The company currently offers a small selection of both conventional and inverter generators under the Onan product line, formerly the Cummins Onan brand.
