Description
Zoom on the Westinghouse WGen9500DFc EFI
To sum up, the Westinghouse WGen9500DFc EFI is a powerful portable generator tailored for:
- Small homeowners in search of a full power backup solution
- 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 Westinghouse WGen9500DFc EFI delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 9,500W and a peak wattage of 12,500W. When powered by propane, it delivers 8,500 running watts and 11,200 peak watts.
Featuring a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator is equipped with both a conventional pull-start mechanism and an easy-to-use and reliable electric starter (battery included) for starting. For added user convenience, the WGen9500DFc 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.
Regarding its running time, the WGen9500DFc EFI, with a 6.6 gallons fuel capacity, can operate for up to 15 hours with a full tank of gasoline (fuel consumption around 0.66 GPH). When using propane, it can run for around 8.7 hours (on a 20 lbs tank - propane consumption around 0.54 GPH).
Given the WGen9500DFc EFI's high Total Harmonic Distortion (THD) of less than 23%, it is advisable to avoid using it to power sensitive electronic devices.
Outlets
The control panel is equipped with the following 6 AC outlets:
Moreover, it boasts 2 DC outlets: there's two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.
As the WGen9500DFc EFI holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
Westinghouse's ST Switch Outlet

The ST Switch outlet
The WGen9500DFc EFI is what Westinghouse calls Smart Switch Ready. This means that it features a special outlet that allows for an automatic transfer of power in case of a power outage.
To benefit from this feature, you'll need the Westinghouse ST Switch (opens in a new tab), which is not included with the generator.
Simply put, the ST Switch is a cost-effective and versatile portable automatic transfer switch, which can be installed quickly and easily, without an electrician.
Plug the ST Switch into one of your household 120V outlets, plug your appliances to the ST Switch, and connect the WGen9500DFc EFI to the ST Switch via the special outlet and a 120V cord. The generator will automatically turn on when the power goes out, and automatically turn off when the power returns.
Portability
Measuring L27.3 x W20.6 x H22.5 in, the classic open frame construction of the Westinghouse WGen9500DFc EFI provides stability while enabling convenient maintenance access to components and adequate air cooling. The device has been designed for tough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 221 pounds. Despite the restricted maneuverability, its wheel kit and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.
Features
The control panel of the WGen9500DFc EFI includes a convenient meter, showing voltage, frequency, and lifetime hours metrics, helpful for the monitoring of its status and activity. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.
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.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Westinghouse WGen9500DFc EFI ships with supplementary accessories: key fob, battery charger, funnel, propane hose, tool kit and oil.

The Westinghouse WGen9500DFc EFI versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500DFc EFI compare to dual fuel generators of similar power (between 9000 and 10000 W).
- At 221 lbs, the Westinghouse WGen9500DFc EFI stands out as one of the heavier dual fuel generators rated from 9000 to 10000 watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Westinghouse iGen11000DFc, with a dry weight of just 187.4 pounds.
- When comparing it to devices with a similar running wattage, this generator's lowest noise level of 74 dBA puts it alongside the noisier units. If you are concerned with noise, check out the DuroMax XP11000iH, which is one of the least noisy generators in its power range, with a noise rating of just 61 dBA.
- The WGen9500DFc EFI, falls within the average autonomy range compared to dual fuel generators of a roughly same power, with a run time of around 10 hours at a 50% load and a full tank. If run time is one of your main concerns, the Westinghouse iGen11000DFc could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 12 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator provides one of the best fuel efficiency among its peers of comparable power output, consuming approximately 0.66 GPH (gallon per hour) at 50% load.
Price comparison
As you can see from these interactive charts, when compared to other 9000-10000W dual fuel generators, the Westinghouse WGen9500DFc 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 Westinghouse
The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators. Portable generators – the main product of the Outdoor Power Equipment branch of Westinghouse – used to be manufactured by Westpro Power Systems, which was bought in 2016 by Midwest Equipment. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, they are in many cases manufactured in China and Vietnam.
