Description
Zoom on the Westinghouse WGen9500DF
In a nutshell, the Westinghouse WGen9500DF 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 ensure that a power failure will not prevent them from working
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 WGen9500DF
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.
Enjoying a noise rating of 73 dBA (just slightly more noisy than a shower), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included). To add further convenience, the WGen9500DF can be remotely started (key fob included).
The running time of the WGen9500DF, with its 6.6 gallons fuel capacity, can reach up to 17.5 hours on a full tank of gasoline (fuel consumption around 0.38 GPH). With propane, it can reach up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH).
The WGen9500DF is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<23%).
Outlets
The control panel features the upcoming 6 AC outlets:
Because the WGen9500DF is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Westinghouse's 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.
Portability
The Westinghouse WGen9500DF has a conventional, open frame design, of the following dimensions: L27.2 x W26.5 x H26 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
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 220 lbs. However, its challenging mobility is solved by its wheel kit (⌀10") and its folding handle, which will ease its displacement, once it is on the floor.
Features
The WGen9500DF's control panel
The WGen9500DF's status and activity may be monitored conveniently via the control panel, as it features 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 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.
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: tool kit, funnel, oil, battery charger, propane hose and key fob. An official storage cover is also available, as a separate purchase.
Emissions
The Westinghouse WGen9500DF is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.
Product Videos
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 generators of similar power (between 9000 and 10000 W).
- As far as its dry weight is concerned, the Westinghouse WGen9500DF weighs just 220 pounds and thus, it is one of the lighter 9000 to 10000 rated wattage generators. Regarding dry weight, one of the champions in the same power range is the Rainier R12000DF, with a dry weight of only 196 lbs.
- Since this generator is rated for a lowest possible noise of 73 dBA, it can be considered as one of the more quiet of the products generating similar power. 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 SUA12000ED, whose lowest noise levels reach just 69 dBA.
- The WGen9500DF provides one of the highest run time among similarly powerful devices, reaching up to 17.5 hours at 25% load.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. With an estimated gasoline consumption of 0.38 GPH (gallon per hour) at 25% load, this generator is among the most fuel efficient of the products in the above-mentioned wattage range.

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".

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!
FANTASTIC GENERATOR. ALL PRO’S
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.
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
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.
