Zoom on the Westinghouse WGen12000DF
In a nutshell, the Westinghouse WGen12000DF is a powerful portable generator mostly geared towards:
- Professionals who want to ensure that a power failure will not prevent them from working
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
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 WGen12000DF allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 12,000W and a starting wattage of 15,000W. If propane-powered, it gives 10,800 rated watts and 13,500 starting watts.
The generator features a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner). Moreover, to offer you even more convenience, the WGen12000DF can also be remotely started (key fob included).
With a fuel capacity of 10.5 gallons, the WGen12000DF can operate for around 11 hours at 50% load using gasoline (fuel consumption around 0.95 GPH), or for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.
The WGen12000DF generates a clean sine wave: providing <5% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel features the upcoming 7 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.
While this Westinghouse generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, as the WGen12000DF 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 WGen12000DF 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 WGen12000DF 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 WGen12000DF has the following dimensions: L34 x W31 x H35 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 352 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.
The control panel of the WGen12000DF 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.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Westinghouse WGen12000DF also comes with some accessories: key fob, propane hose, tool kit, battery charger, funnel and oil are included.
The Westinghouse WGen12000DF 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, making it usable in forested areas.
The Westinghouse WGen12000DF versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen12000DF compare to dual fuel generators of similar power (between 10000 and 14000 W).
- As its dry weight is 352 pounds, the Westinghouse WGen12000DF is one of the heavier of the dual fuel products which can generate 10000 to 14000 running watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PG13000BRCO, with a dry weight of only 231 lbs.
- Since this generator is rated for a lowest possible noise of 74 dBA, it can be considered as one of the most quiet of the products generating similar power.
- With a run time of around 11 hours at 50% load, the WGen12000DF has one of the highest run times, compared to its similarly powerful peers.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator is one of the most fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.95 GPH (gallon per hour) at 50% load.

Being an off the grid rancher for many years, I have owned many generators(Champion, Cummins/Onan, Generac and WGen9500DF-all with very minor problems). I purchased a Westinghouse WGen12000DF generator in 2020. It lasted 244 hours before it died. Their customer service department had me changing almost every part on the generator until they finally conceded that the generator was defective. It then took them two moths to replace it. The replacement WGen12000DF lasted 202 hours before it died. Now they have me changing parts again(which is not working). I have asked for a refund of the purchase price or I will take legal action. Do not purchase the Westinghouse WGen12000DF.
Short version, tech support sucks, but I was able to get the generator to perform to specs, no thanks to them.
I was on the verge of returning the generator. Generator 5/5. Tech support 0/5 on both the first and second one I received.
I bought the wgen 12000df it has Plenty of power to run my house and then some. The generator works like a charm. It starts with no issues. The push button start works as it should and so does the key fob. I do wish it had a backup recoil start. I like the trickle charger that it comes with.
Purchased new July 2020. 15000/12000 watt capacity perfect size, fit & finish very good. Generator would start, speed up & then stop. Would not run. Returned to Westinghouse for refund.
Generator would not run. Westinghouse tech support was AWFUL !
