Zoom on the Westinghouse WGen9500DF
In a nutshell, the Westinghouse WGen9500DF is a powerful portable generator mostly geared towards:
- Homeowners who wish to power almost all appliances in their house under any circumstances
- Professionals who want to be able to deliver results, even during a power failure
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- RV travellers looking for even more independence
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
Thanks to its dual-fuel technology, the Westinghouse WGen9500DF delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9500W and a peak wattage of 12500W. When propane-powered, it has 8500 rated watts and 11200 peak watts.
The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). The WGen9500DF can also be remotely started, offering further convenience (key fob included).
With a fuel capacity of 6.6 gallons, the WGen9500DF can operate for up to 17.5 hours using gasoline (fuel consumption around 0.55 GPH), or for up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) using propane.
Since the WGen9500DF has a somewhat high THD (<23%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel provides the upcoming 6 AC outlets:
If you own an RV with a 50-amp service, you can consider this Westinghouse unit as RV-ready, as it features a 14-50R outlet. In addition, due to the featured twist-lock L14-30R receptacle, the WGen9500DF is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Westinghouse's ST Switch Outlet
The WGen9500DF 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 WGen9500DF 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.
The Westinghouse WGen9500DF has the following dimensions: L27.2 x W26.1 x H26.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 211 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
To help you monitor the WGen9500DF's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse WGen9500DF's package also includes these accessories: propane hose, oil, tool kit, funnel, key fob and battery charger. An official storage cover is also available, as a separate purchase.
The Westinghouse WGen9500DF is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
The Westinghouse WGen9500DF versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500DF compare to dual fuel generators of similar power (between 9000 and 10000 W).
- In terms of its dry weight, the Westinghouse WGen9500DF stands at only 211 lbs, meaning that is one of the lighter dual fuel devices of the 9000-10000 rated wattage category In terms of weight, one of the champions in their power range is the Pulsar PG12000B, standing at just 205 lbs.
- This generator has a somewhat average expected noise for its type and power range, rated at 74 dBA. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA12000ED, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
- With a run time of around 12 hours at 50% load, the WGen9500DF has one of the highest run times, compared to its similarly powerful peers.
- 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 can be considered as one of the most fuel efficient, due to its low estimated fuel consumption of only 0.55 GPH (gallon per hour) at 50% load, within the aforementioned wattage range.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 9000-10000W dual fuel generators, the Westinghouse WGen9500DF is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

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, several sources report that they are in many cases manufactured in China.
The Westinghouse WGen9500DF is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.

Is it safe to charge/run delicate equipment such as TV, computers, cell phones? (Asked June 15, 2020)
THD should be under 5% to safely run devices that contain sensitive electronics. This unit's THD is <23%, and thus, too high.
does this gen have idel control? (Asked September 06, 2020)
This unit does not have an idle control feature.
Can it also be converted to natural gas? (Asked September 21, 2020)
There are no official conversion kits.
I understand that you can’t run computers etc. But, is it okay to charge a battery powered laptop since the charger is plugged in to just charge the battery as long as you don’t use the laptop while its charging? (Asked October 21, 2020)
Not if you value the circuitry of your charger. Your laptop works on DC, not on AC.
If run through a 50 amp transfer switch and breakers can you safely use tv, charge cell phones, computers? (Asked November 03, 2020)
A transfer switch does not clean power, it just transfers it.

Can this generator be outside during winter snow storms, How low the temperature can be in order to be outside? to storage can be in a non heated garage in winter time? (Asked December 17, 2020)
The unit is rated for operation between 5°F and 104°F. In case of exposure outside of this range during storage, it should be brought back within this range before operation. You may also read our article on rain and snow operation.
What is THD ? (Asked September 07, 2021)
THD stands for Total Harmonic Distortion. The lower the THD, the closer you get to a proper sinewave. You can read more about it in this article.
What size is the propane hose delivered with the generator? can you add an extension hose to the existing hose? What size fittings would the esxtension hose have? (Asked September 15, 2021)
The included propane hose is about 3 ft long. Fittings would have to be 3/8".
