Zoom on the Westinghouse WGen9500DF
In summary, the Westinghouse WGen9500DF is a powerful portable generator especially useful for:
- 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 who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- 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 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.
Enjoying a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included). For additional convenience, the WGen9500DF may also be remotely started (key fob included).
Regarding its running time, the WGen9500DF, with a 6.6 gallons fuel capacity can operate for up to 12 hours with a full tank of gasoline (fuel consumption around 0.83 GPH). When using propane, it can run 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 following 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, as the WGen9500DF holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home 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.
With its dimensions of L27.2 x W26.1 x H26.5 in, the conventional, open frame design of the Westinghouse WGen9500DF offers stability and allows the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 211 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.
The WGen9500DF's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Westinghouse WGen9500DF, the following accessories are also included: propane hose, key fob, tool kit, funnel, oil and battery charger. An official storage cover is also available, as a separate purchase.
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, 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).
- Regarding its weight, the Westinghouse WGen9500DF only weighs in at 211 pounds, which means it's one of the lighter dual fuel generators in the 9000-10000 rated wattage range. In terms of weight, one of the champions in their power range is the Pulsar PG12000B, standing at just 205 lbs.
- The generator can be considered average in its noise for its type and power category, as it is 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 SUA12000ED, whose lowest noise levels reach just 69 dBA.
- Regarding its autonomy, the autonomy of the WGen9500DF, reaching around 8 hours at a 50% load, can be considered as low end, compared to other dual fuel products of a roughly equal output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Pulsar G12KBN, with around 12 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. This generator, with an estimated fuel consumption of just 0.83 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Pulsar G12KBN, which has a fuel consumption of only 0.67 GPH and thus, is one of the most efficient devices in our database.
Here's a list of the most popular specific comparisons:

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.
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.
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.
FANTASTIC GENERATOR. ALL PRO’S
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!
