Zoom on the Westinghouse WGen9500DF

In a nutshell, the Westinghouse WGen9500DF is a powerful portable generator mostly geared towards:

  • Small homeowners in search of a full power backup solution
  • Professionals who want to ensure that a power failure will not prevent them from working
  • Homeowners in need of an emergency backup power for their essentials
  • RV travellers who wish to upgrade their experience to another level

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Westinghouse WGen9500DF in use

The Westinghouse WGen9500DF

The dual-fuel technology of the Westinghouse WGen9500DF allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 9,500W and a starting wattage of 12,500W. If propane-powered, it gives 8,500 rated watts and 11,200 starting watts.

At a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included). For additional convenience, the WGen9500DF may also be remotely started (key fob included).

As for its running time, the WGen9500DF, along with its 6.6 gallons fuel capacity, can run for up to 12 hours with a full tank filled with gasoline (fuel consumption around 0.55 GPH). If propane is used, it can operate for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).

The WGen9500DF is unsuitable for the powering of sensitive electronic devices due to its high THD (<23%).


The control panel features the upcoming 6 AC outlets:

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

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 WGen9500DF 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 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 a conventional, open frame design, of the following dimensions: L27.2 x W26.1 x H26.5 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 211 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.


Panel of the Westinghouse WGen9500DF

The WGen9500DF's control panel

The control panel of the WGen9500DF includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Westinghouse WGen9500DF also comes with some accessories: oil, battery charger, propane hose, funnel, tool kit and key fob are included. The official storage cover and running cover are also available, as separate purchases.


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, so it is adequate for use 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).

  • As its weight is 211 pounds, the Westinghouse WGen9500DF falls in the expected weight range of the dual fuel devices in the 9000-10000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Westinghouse iGen11000DFc, with a dry weight of only 187.4 lbs.
  • As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Westinghouse iGen11000DFc. With just 64 dBA, it is one of the most quiet devices in this power range.
  • As far as autonomy is concerned, providing around 8 hours of runtime with a full tank at a 50% load, the WGen9500DF falls into the low end in comparison with other dual fuel devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen11000DFc, as it provides around 12 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. As this generator uses an estimated 0.83 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.66 GPH, the Westinghouse iGen11000DFc is a device you could look out for.

Price comparison

As you can see from these interactive charts, 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 bottom line

  • In the expected price range
  • Dual Fuel
  • Several accessories included
  • GFCI Outlets
  • Remote start
  • Smart Switch Ready
  • Decent weight (211 lbs)
  • Acceptable noise (74 dBA)

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.

Does the Westinghouse 9500 have an oil filter? An oil filter I can change when I change oil? (Asked November 03, 2020)

The WGen9500DF does not have an oil filter.

Is it safe to use with computers, laptops, cell phones, etc. if those items are plugged into a high end APC UPS unit in between this source? (Asked November 08, 2020)

It would have to be a double-conversion online UPS (opens in a new tab), which will first convert AC to DC, then DC back to AC.

how to remove bonded neutral (Asked December 10, 2020)

You can follow Westinghouse's guidelines (opens in a new tab) or refer to our article on neutral conversion.

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".

If hooking this up to a 250 gallon propane tank at the house supply line, what pressure does the hook up need to be? Or what pressure range does the generator need for supply? (Asked December 10, 2021)

The pressure as measured at the regulator mounted to the generator must be 7” to 14” of water column.

    Ran on propane for 50 hours. Very noisy front end. Choke stopped working. Would not start. Westinghouse directed me to a repair center where I, 77 year old man, had to deliver this 315 pound generator. A week, bad genset, replaced. New one is working OK at 10 hours. This generator is a rebranded Chinese unit that was once known as Powerlift. I know this because I have a powerlift and this Westinghouse, apart from the auto choke and remote start is identical in every detail. Motor, gas tank, vibration mounts, frame design, generator attachment and rear cover, valve cover, number of visible engine cooling fins and color. No significant differences. And while I have not torn into it, I’ll bet the internals are the same as well. So, is this an average deal for $1,000? Hard to say. My Generac ran 2700 hours and cost me $3000. This one has some work to do to get to that price point. We will see.

    + PROS:
    • Great price point and Westinghouse is good on the warranty work so far.
    - CONS:
    • Advertised as something special (cast iron cylinder sleeve) but is anything but. The Wright flyer engine had cast iron cylinder sleeves in 1901.

  2. 3.75

    I’ve liked everything about the generator so far. I’ve used it maybe 5 times in 2 years for a total of 25 hours run time. I tested it on both fuels when I first purchased it but under real conditions, I’ve only run it on propane. Didn’t want to end up with gas left in the tank. This was purchased to run the entire house, except for the central air conditioning so I use the 50 AMP outlet. I purchased a Conntek GIB1450-025 Duo-Rain Seal 50Amp Power Inlet Box and Temp Power Cord Combo Kit, 25 Feet. Installed a lock out in my main breaker box and a 50 AMP breaker. No problems with the installation. The power cord is STW 6/3 + 8/1. In the process of getting 2-100 lbs. propane tanks and setting them up with quick disconnects to be able to quickly get the generator up and running when needed.

    Now for the dislike. This is more of an inconvenience than anything. If you look at the location of the 50 AMP outlet on the generator, you’ll notice it is right above the wheel. The 50 AMP power cord I purchased is at a 90 Degree angle which is fine with me, less strain on the cord. The cord is so stiff that in order for the plug to stay attached to the generator I have to take the wheel off so the power cord hangs free. If you’re going to use the 50 AMP outlet and can find a power cord that is 45 Degrees on the male end, you’ll save yourself time when hooking up the generator. I haven’t found one. Not sure if it’s even made. Other than that, the generator is everything it was advertised as.

    + PROS:
    • The generator is everything it was advertised as
    - CONS:
    • This is more of an inconvenience than anything. If you look at the location of the 50 AMP outlet on the generator, you’ll notice it is right above the wheel.

    After Houston, TX experienced a freeze in February that left my house without power for two full days, I did some quick research and when demand eased a bit, I bought the WGen9500DF. Very pleased that it runs my central A/C (3 tons) and everything else in my house.

    I’ve seen a couple of reviews with complaints about starting issues, etc. Mine started the very first time, and has started easily every time. I’d guess I’ve fired it up a dozen times, maybe more.

    Actually needed it about 2 weeks ago when a thunderstorm cut power to my neighborhood for a couple of hours. Gives great peace of mind knowing I can depend on this generator in times when I cannot depend on the grid.

    + PROS:
    • Competitively priced. Electric start: Started quickly the 1st time I connected propane, started every time since. Runs my 3 ton central A/C and the rest of my house.
    - CONS:
    • Wheels are plastic and a bit cheap.

    It dies does not want to start up! Right out of the box did not start up. tied 10 times. took it to an authorized dealer they said it was fixed and I had to PAY! Still new? They said carb was dirty and not enough oil. I put exactly what was in the box! Drove 30 minutes did not start up. was called again ready to pick up. Again it did not work! Want my money back! There are issues with this machine per the repair place! DO NOT BUY

    Initially bought this about 1.5 years ago. Arrived in good shape and would not start. Turns out the start switch on the panel was faulty based on my testing because it would pull start AND the remote start worked just fine. I called customer service and they offered to send me a new switch. When it arrived I realized pulling that panel out was a pain and I did not want to mess up the wiring in any way so they authorized repair center to do work. I have to haul it there (in my city) which was a pain because this is heavy. They repaired switch and it worked fine. Always easy to start, worked on both fuels. Was happy. Up until then I only used 20A outlets and the 30A outlet. I wired in backup to my house and switched to the 50A outlet and only one side was hot. The outlet was not functioning! I did not find this out until about 1 year into ownership and customer service said “tough luck”. I told them it had just been serviced and perhaps the service center damaged the wiring? Still no help. I decided to tear apart panel myself and sure enough found a connecter was disconnected for a logic board.I put it together an now works fine. So, overall this is a lot of power and seems to work well but only after I diagnosed it and messed with it myself. Quality control and customer support could be better. Test EVERYTHING when you buy it thoroughly and I bet they will stand by it, but after 1 year even probelms that they created they will not help with.

    + PROS:
    • Apparent nice build quality, useful outlets, initially had good customer service, reliable start
    - CONS:
    • Poor quality control, service centers with questionable quality, and then abandoned by customer service.

    WGen9500DF (Dual Fuel)

    This is an outstanding generator. First, it was difficult to find it in stock at any of the big-box stores over the course of a couple months, let alone Amazon or other smaller vendors. Most of the reviews I read were overwhelmingly positive, and clearly this is an extremely popular generator. Now that I have tested and proven it – – I understand why.

    I ordered it mid-April and it arrived first week of June. The generator was in its original cardboard packaging secured by two typical plastic straps and was without any damage or perforations. Upon opening and visual inspection, the contents were present and securely packaged as described by Westinghouse (oil, tool kit, propane hose/regulator, remote FOB, etc.). The manufacturing and serial number information states “Made in Vietnam”.

    I hired a local, reputable electric company to install a 50-amp generator receptacle outlet, circuit, and interlock kit on my main breaker panel (required by city code) the day after the generator’s arrival. I prepped the genny prior to the install by following the Owner’s Manual instructions and had no problems (feet, wheels, battery, or oil). It did need just a bit more oil (maybe 3-4 oz.) to top off the oil fill-line. I selected propane for its first fuel, ran it for 5 minutes and then switched to gas. Both were flawless. My wife is able to easily move it as well. I was now ready for the electricians to install the designated outdoor receptacle/circuits/breaker and interlock kit the following day.

    Fantastic! Even my electricians were impressed with the features and performance of this generator. It powered my 3.5 ton central A/C and a few other nominal circuits. However, the A/C is not my primary intent, as that was only to see if it could…and it did. I have a portable A/C & heater that I will plug if needed, rather than using central A/C. I also researched each of my circuits to ascertain their wattage usage in order to designate the circuits I would power on for the generator. I printed that spec-sheet and it is affixed to the inside breaker panel for reference when using the generator power. With proper maintenance, I expect to get many years of reliable service from this beast. My previous generator was a 6500-watt electric start which I gave to a friend, and it is still performing well after 12 years. I am very pleased with this WGen9500DF and highly recommend it. Best wishes!

    + PROS:
    • Outstanding Performance and Power. Generous features with great quality.
    - CONS:
    • What's not to like?
