In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Westinghouse WGen9500
The Westinghouse WGen9500's core is the 457 cc (13.5 hp) Westinghouse OHV 4-stroke engine with cast iron sleeve, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 9,500W and a peak wattage of 12,500W.
The generator features a traditional recoil pull-start mechanism and also a no-fuss and convenient electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a shower). Furthermore, the WGen9500 can be remotely started, providing users with added ease of use (key fob included).
With a fuel capacity of 6.6 gallons, the WGen9500 can run for up to 12 hours when the tank is full (fuel consumption is approximately 0.55 gallons per hour).
Since the WGen9500 has a high THD (<23%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel provides the upcoming 6 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports providing convenient charging capabilities for mobile phones, tablets, and other electronic devices.
With its 14-50R outlet, this Westinghouse unit is RV-ready for owners with a 50-amp service in their RVs. In addition, since it boasts a twist-lock L14-30R receptacle, the WGen9500 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Westinghouse's ST Switch Outlet
The ST Switch outlet
The WGen9500 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 WGen9500 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
With dimensions of L27.2 x W26.5 x H26.5 in, the standard open frame design of the Westinghouse WGen9500 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.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 208 lbs make it incredibly difficult to manually lift and transport. Despite the restricted maneuverability, its wheel kit (⌀10") and its folding handle provides a solution, allowing for convenient shifting once the generator is positioned on the ground.
Features
The WGen9500's control panel
The control panel of the WGen9500 is equipped with a convenient meter, providing voltage, frequency, and lifetime hours data, aiding in monitoring its status and activity.
With its built-in fuel gauge, the generator provides quick and convenient gas level checks.
From a security standpoint, the generator is furnished with an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during operation.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Westinghouse WGen9500 ships with supplementary accessories: tool kit, oil, key fob, battery charger and funnel. The official storage cover and running cover are also available, as separate purchases.

The Westinghouse WGen9500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500 compare to generators of similar power (between 9000 and 10000 W).
- Considering its weight, the Westinghouse WGen9500 registers at a modest 208 pounds, placing it among the lighter generators in the 9000 to 10000 rated wattage selection. If weight is a key factor for your needs, the Westinghouse iGen11000DFc is noteworthy for being one of the top contenders in this power range, with a dry weight of 187.4 pounds.
- Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you wish to prioritize minimal noise, the DuroMax XP11000iH stands out as one of the quietest options among generators of similar power, with a rating of 61 dBA.
- Regarding its autonomy, the WGen9500 can run for up to 12 hours at a 25% load, aligning it with the lower performers in its power range. If prolonged run time is essential to your needs, you could consider the Westinghouse iGen11000TFc, which offers one of the highest autonomy among devices with similar power output, lasting up to 19 hours.
- While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. 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 0.55 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the DuroMax XP11000iH. With a fuel consumption of as little as 0.39 GPH, it is one of the most efficient generators currently on the market.
Here's a list of the most popular specific comparisons:
The bottom line
- Several accessories included
- GFCI Outlets
- Remote start
- Smart Switch Ready
- Lightweight for its kind (208 lbs)
- Acceptable noise (74 dBA)
- Relatively low run time
- Low fuel efficiency

Does it come with wheels and the battery. Does the battery charge as you run it. (Asked May 27, 2020)
The wheel kit and the battery are included. The generator does charge the battery when it runs. However, to ensure that the battery remains charged, the WGen9500 should be started every 2 to 3 months and run for a minimum of 15 minutes. Otherwise, you'll have to use a charger.
Westinghouse w gen9500 have propane hook up capability? (Asked August 08, 2020)
For propane operation, you'd be looking at the WGen9500DF, which is the dual fuel version.
Can you both Start AND Shut Off the generator with the remote (key FOB)? (Asked September 30, 2020)
Absolutely. The key fob has 2 buttons. One to start the unit, and one to stop it.
Is the width dimension of 26.5" with the wheels on? If not, what is that dimension? (Asked February 01, 2021)
This is the assembled width, so with the wheels.
Can the 30amp outlet be wired to one transfer switch and the 50amp outlet wired to a second transfer switch. (Asked May 22, 2021)
There's no reason why this should not be possible, as long as NEC is respected.
Does this really run up to 17.5hrs at 25% as stated on this page? All I see, even on the MFG website is 12 hours. Anyone successfully have it run that long? How was this calculated? (Asked June 15, 2021)
This was not calculated, since these are the official manufacturer specs at 25% load. The 12 hours mentioned on the MFG website are at 50% load. This information is also available in the spec table above.
Is there a dual fuel model like this that has the DC ports like the WGEN9500, even a different brand? (Asked July 15, 2022)
Please have a look at this list of dual fuel units with DC output and at least 9000 running watts.
Can I run two of the Westinghouse 9500df generators in parallel? (Asked December 28, 2022)
The unit is not parallel capable.

User Reviews
This 9500 watt generator powered my house for 2 days while waiting for power to be restored in Farwell, Michigan, in December, 2025. It ran flawlessly on propane for the entire time. Up to that time, it had not been run from brand new start up after purchase last summer. One of the better purchases that I have made. A power outage is not something that you want to have happen, especially at this time of year, but I do not have to worry about this anymore.
Received this generator a few months ago, the directions and assembly guides were easy to follow and setup was a breeze. The generator started right up in all three functions, instructions were very simple. Using propane to operate this unit is very safe and less of pain to use the fuel tank. Dual fuel operation makes it way easier to use. Had a transfer switch professionally installed on the house and connected the generator to ensure it would run essential appliances during a power outage, and it was successful. Both the house and the generator performed as expected. I feel confident that this unit will provide the power needed to keep us safe for future storms to come. I would definitely recommend this unit to all of my friends and family members .
This generator is not a good generator for real world use…would not Last a few months before the fixing starts…wildfire surviver.
Very nice generator especially for the price. Super easy to set up and test. Quieter than expected. Cannot find a flaw on it. The only thing keeping me from going with 5 stars on the performance was the inability to source a Westinghouse Smart Switch which I specifically purchased this generator to work with. Home Depot, Amazon, Lowes, E-bay all sold out, no word on when it will come back in stock. Also created a case with Westinghouse January 3rd (10 days ago) regarding this issue and sent 2 more emails and haven’t heard a response yet.
