Description
Zoom on the Cummins Onan P5000iDF EFI
In short, the Cummins Onan P5000iDF EFI is a quiet and compact portable inverter generator adequately designed for:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
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
The Cummins Onan P5000iDF EFI, equipped with dual-fuel technology and delivering 120V, ensures both power and versatility. Running on gasoline, it delivers a running wattage of 3,900W and a starting wattage of 5,000W. On propane, it provides 3,500 running watts and 4,500 starting watts. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.
At a noise rating of 52 dBA (just slightly more noisy than rainfall), this inverter generator can be started via a classic hand-operated recoil starting mechanism, or a user-friendly and hassle-free electric starter (battery included). The Onan P5000iDF EFI can also be remotely started, offering further 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.
Regarding its running time, the Onan P5000iDF EFI, with a 3.4 gallons fuel capacity, can operate for up to 16.8 hours with a full tank of gasoline (fuel consumption around 0.2 GPH). When using propane, it can run for up to 20 hours (on a 20 lbs tank - propane consumption around 0.24 GPH).
Thanks to its low <3% Total Harmonic Distortion (THD), the Onan P5000iDF EFI produces a clean sine wave output, making it safe for your sensitive electronics when utilizing the AC outlets.
Outlets
The control panel features the following 3 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.
This Cummins generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The Cummins Onan P5000iDF EFI is distinguished by its enclosed inverter generator design (L25.1 x W18.1 x H21.2 in), providing improved aesthetics and quieter performance compared to traditional, open frame units. This modern design aims to provide an ideal power solution to recreational users.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 108 pounds. However, the constrained maneuverability is addressed with the assistance of its set of 2 wheels (⌀5.5") and its telescopic handle, allowing for easy shifting once the generator is placed on the ground.
Features
Designed with a digital data center, the control panel of the Onan P5000iDF EFI grants you access to crucial data on the lifetime run hours, frequency, fuel level, power output and voltage, ensuring practical monitoring of its status and activity.
In addition to this info, light indicators on the device will notify you if the generator is overloaded, the generator is ready and the oil level is too low.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, 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.
In addition to the traditional documentation and an owner's manual to help you get started promptly, the Cummins Onan P5000iDF EFI also includes several accessories: battery charger, key fob, oil, tool kit, funnel and propane hose.
The Cummins Onan P5000iDF 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 P5000iDF EFI compare to inverter generators of similar power (between 3500 and 4500 W).
- At a weight of 108 pounds, the Cummins Onan P5000iDF EFI places in the expected weight range of the inverter generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN 56432iX, weighing just 52.9 pounds.
- At just 52 dBA rated noise level, this inverter generator is positioned as one of the quietest choices among devices delivering similar type and power.
- As the Onan P5000iDF EFI offers up to 16.8 hours run time on a full tank at a 25% load, it falls within the average autonomy range among the inverter generators of a similar power. If you wish to prioritize autonomy, the Firman WH03662OF shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling up to 25 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. This inverter generator has an estimated fuel consumption of roughly 0.2 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Champion 201319, which boasts with a gas consumption of only 0.16 GPH, may be the right generator for you.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W dual fuel inverter generators, the Cummins Onan P5000iDF EFI is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end 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.
