Zoom on the Westinghouse WGen12000DF
In summary, the Westinghouse WGen12000DF is a powerful portable generator especially useful for:
- 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 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 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 simple and elegant electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a shower). The WGen12000DF can also be remotely started, offering further convenience (key fob included).
Regarding its running time, the WGen12000DF, with a 10.5 gallons fuel capacity can operate for around 11 hours at 50% load with a full tank of gasoline (fuel consumption around 0.95 GPH). When using propane, it can run for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).
Delicate electronics can be plugged in an AC outlets safely, as the WGen12000DF generates a clean sine wave, reaching a <5% Total Harmonic Distortion (THD).
Outlets
The control panel features the upcoming 7 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.
This Westinghouse generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, due to the featured twist-lock L14-30R receptacle, the WGen12000DF is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Westinghouse's ST Switch Outlet

The 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.
Portability
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 generator is designed for ideal use outdoors and in rough environments.
As the generator's weight is 352 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.
Features
To help you monitor the WGen12000DF's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Westinghouse WGen12000DF, the following accessories are also included: oil, key fob, battery charger, propane hose, tool kit and funnel.
Emissions
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 and therefore, can be used 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).
- Considering its dry weight of 352 pounds, the Westinghouse WGen12000DF is one of the heavier dual fuel generators producing between 10000 and 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.
- With a lowest noise rating of 74 dBA, the generator is one of the more quiet of the generators of similar type and power. For those who are looking for a less noisy device, we suggest the DuroMax XP16000iH. With just 67 dBA, it is one of the most quiet devices in this power range.
- With a run time of around 11 hours at 50% load, the WGen12000DF has one of the higher run times, compared to its similarly powerful peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP15000HX, boasting 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 can be considered as one of the most fuel efficient, due to its low estimated fuel consumption of only 0.95 GPH (gallon per hour) at 50% load, within the aforementioned wattage range.
Here's a list of the most popular specific comparisons:

User Reviews
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 !
