Description

Zoom on the Cummins Onan P9500DF EFI

In short, the Cummins Onan P9500DF EFI is a portable generator adequately designed for:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

With its dual-fuel technology, the Cummins Onan P9500DF EFI delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 7,500W and a peak wattage of 9,500W. When powered by propane, it delivers 6,750 running watts and 8,550 peak watts.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator offers the versatility of starting with either a classic hand-operated recoil starting mechanism or a convenient and easy-to-use electric starter (battery included). For added user convenience, the Onan P9500DF EFI is equipped with remote starting capabilities (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.

Concerning its running time, the Onan P9500DF EFI, featuring a 6.6 gallons fuel tank, can continuously run for up to 14.4 hours with a full gasoline tank (consuming fuel at approximately 0.46 gallons per hour). Alternatively, when utilizing propane, it offers up to 10.8 hours (on a 20 lbs tank - propane consumption around 0.44 GPH) of runtime.

Due to the high THD (<23%) of the Onan P9500DF EFI, it is advised against using it for powering sensitive electronic devices.

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.

With its twist-lock L14-30R receptacle, the Onan P9500DF EFI is designed to be transfer switch ready, allowing easy connection to your breaker box for powering your home during a blackout.

Portability

With dimensions of L27.3 x W20.6 x H22.6 in, the standard open frame design of the Cummins Onan P9500DF EFI provides stability and easy maintenance access to components, as well as good air circulation. The featured design is ideal for the outdoors and all tough environments.

Despite its 211.6 lbs, the generator falls under the category of 'portable,' signifying its movability, although its weight may hinder 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 facilitate status and activity monitoring, a convenient meter, displaying voltage, frequency, and lifetime hours information are embedded in the control panel of the Onan P9500DF EFI.

Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.

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.

Apart from the typical documentation and an owner's manual, which lets you start it right away, the Cummins Onan P9500DF EFI also is packed along with the following accessories: propane hose, funnel, oil, key fob and tool kit.

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).

  • With a dry weight of 211.6 lbs, the Cummins Onan P9500DF EFI falls within the expected weight range for dual fuel generators in the 7000 to 8000 rated wattage. Weight-conscious users may find the Sportsman GEN85KIDF appealing, as it is one of the top contenders in this power range, weighing just 133 pounds.
  • The generator can be considered average in its noise for its type and power category, as it is rated at 74 dBA. If you are concerned with noise, check out the DuroMax XP9500iH, which is one of the least noisy generators in its power range, with a noise rating of just 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 consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP10000EH, with 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. This generator doesn't excel in fuel efficiency when compared to others of its kind: it consumes approximately 0.46 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the DuroMax XP9500iH, which boasts with a gas consumption of only 0.34 GPH, may be the right generator for you.

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

The Cummins Onan P9500DF EFI is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
