Description
Zoom on the Cummins Onan P9500DF EFI
In summary, the Cummins Onan P9500DF EFI is a portable generator especially useful for:
- 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 who want to ensure that a power failure will not prevent them from working
In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.
Power & Run Time
Delivering 120/240V, the Cummins Onan P9500DF EFI is enhanced by dual-fuel technology, providing power and versatility. Running on gasoline, it boasts a running wattage of 7,500W and a starting wattage of 9,500W. Alternatively, when propane-powered, it delivers 6,750 running watts and 8,550 starting watts.
With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). Moreover, the Onan P9500DF EFI boasts remote starting functionality, adding another layer of 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.
In terms of running time, the Onan P9500DF EFI, equipped with a 6.6 gallons fuel tank, is capable of running continuously for up to 14.4 hours on a full gasoline tank (with fuel consumption estimated at around 0.46 gallons per hour). When utilizing propane, it provides up to 10.8 hours (on a 20 lbs tank - propane consumption around 0.44 GPH) of operation.
The quite high THD (<23%) of the Onan P9500DF EFI makes it unsuitable for powering sensitive electronic devices.
Outlets
The control panel is equipped with the following 5 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports (USB-A) providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.
Since it features a twist-lock L14-30R receptacle, the Onan P9500DF EFI is tailored to be transfer switch ready, making it easy to connect it to your breaker box for home power support during outages.
Portability
Measuring L27.3 x W20.6 x H22.6 in, the classic open frame build of the Cummins Onan P9500DF EFI delivers stability and easy maintenance access to components, facilitating air circulation. This type of design is ideal for tough environments and heavy outdoor use.
With a weight of 211.6 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀10") and its folding handle, enabling easy shifting once the generator is set in place.
Features
To help you monitor the Onan P9500DF EFI's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Cummins Onan P9500DF EFI ships with supplementary accessories: tool kit, oil, funnel, propane hose and key fob.
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).
- At a weight of 211.6 pounds, the Cummins Onan P9500DF EFI places in the expected weight range of the dual fuel generators in the 7000-8000 rated wattage range. If weight is your top priority, one of the champions in this power category is the Sportsman GEN85KIDF, weighing just 133 pounds.
- Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar type and power. If you'd like a less noisy alternative, the DuroMax XP9500iH is a strong contender. It boasts a noise rating of 61 dBA, placing it among the quietest generators in its power category.
- Regarding its runtime, the Onan P9500DF EFI operates for up to 14.4 hours at a 25% load, positioning it at the lower spectrum among comparable dual fuel products. For those prioritizing autonomy, the DuroMax XP10000EH could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 22 hours.
- Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. 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. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.34 GPH, the DuroMax XP9500iH is a device you could look out for.
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.
Warranty Information
