Description

Zoom on the Westinghouse WGen9500

In a nutshell, the Westinghouse WGen9500 is a powerful portable generator mostly geared towards:

  • Prudent homeowners who want a backup power source in case of a power outage
  • Professionals who want to be able to deliver results, even during a power failure
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • RV travellers who wish to upgrade their experience to another level

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

The Westinghouse WGen9500 in use

The Westinghouse WGen9500

The Westinghouse WGen9500 is powered by a 457 cc (13.5 hp) Westinghouse OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 9,500W as well as a peak wattage of 12,500W.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the WGen9500 can also be remotely started (key fob included).

Thanks to a fuel capacity of 6.6 gallons, the WGen9500 can operate for up to 12 hours with a full tank (fuel consumption around 0.55 GPH).

The quite high THD (<23%) of the WGen9500 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

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, as it features a twist-lock L14-30R receptacle, the WGen9500 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Westinghouse's ST Switch Outlet

Picture of the 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

The Westinghouse WGen9500 has the following dimensions: L27.2 x W26.5 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.

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. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Westinghouse WGen9500

The WGen9500's control panel

The control panel of the WGen9500 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Westinghouse WGen9500's package also includes these accessories: tool kit, key fob, oil, battery charger and funnel. The official storage cover and running cover are also available, as separate purchases.

Emissions

The Westinghouse WGen9500 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

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).

  • Regarding its weight, the Westinghouse WGen9500 only weighs in at 208 pounds, which means it's one of the lighter generators in the 9000-10000 rated wattage range. If weight is your top priority, one of the champions in this power category is the Westinghouse WGen9500TFc, weighing just 203.4 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 74 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA13000EFI, whose lowest noise levels reach just 69 dBA.
  • Regarding its autonomy, the autonomy of the WGen9500, reaching up to 12 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP11500EH, boasting with up to 20 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.55 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP11500EH, with a fuel consumption of 0.42 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 9000-10000W generators, the Westinghouse WGen9500 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

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.

Warranty Information

The Westinghouse WGen9500 is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
For more information about the warranty of Westinghouse generators, please consult Westinghouse's warranty policies (opens in a new tab). Alternatively, you can also contact their Customer Support: 1-855-944-3571.

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” i 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.

    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.

    + PROS:
    • Very nice generator especially for the price. Super easy to set up and test. Quieter than expected. Set up for simple use with a 20A Westinghouse automatic transfer switch. Remote start. Comes with battery, charger, oil, funnel, full documentation.
    - CONS:
    • Cannot find a flaw with it anywhere except one big one: Cannot buy a Smart switch for it anywhere and still waiting for an answer from the Westinghouse Service Team after 10 days.
