Description

Zoom on the Westinghouse WGen12000

In a nutshell, the Westinghouse WGen12000 is a powerful portable generator mostly geared towards:

  • Professionals in need of safely powering high-intensity work or lighting equipment
  • Homeowners in need of an emergency backup power for their essentials

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 WGen12000 in use

The Westinghouse WGen12000

The Westinghouse WGen12000's design includes a gasoline-fueled 713 cc (22 hp) Westinghouse V-Twin engine. With a 120/240V output, it gives a running wattage of 12000W and also a peak wattage of 15000W.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator gets running thanks to a simple and elegant electric starter (battery included). To add further convenience, the WGen12000 can be remotely started (key fob included).

The WGen12000 can operate for up to 16 hours with a full tank (fuel consumption around 0.95 GPH), due to its fuel capacity of 10.5 gallons.

The WGen12000 generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the following 7 AC outlets:

Two Duplexes 120V 20A (5-20R)
120/240V 50A (14-50R) receptacle
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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, due to the featured twist-lock L14-30R receptacle, the WGen12000 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

Picture of the ST Switch outlet

The ST Switch outlet

The WGen12000 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 WGen12000 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 WGen12000 has a conventional, open frame design, of the following dimensions: L34 x W31 x H35 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 352 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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.

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

The WGen12000's control panel

To help you monitor the WGen12000's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

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

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Westinghouse WGen12000 also comes with several accessories, including: key fob, oil, battery charger, funnel and tool kit.

Emissions

The Westinghouse WGen12000 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

The Westinghouse WGen12000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen12000 compare to generators of similar power (between 10000 and 14000 W).

  • A weight of 352 lbs makes the Westinghouse WGen12000 one of the heavier devices in the 10000-14000 rated wattage range. If weight is your top priority, one of the champions in this power category is the A-iPower SUA13000EFI, weighing just 218 pounds.
  • With a lowest noise rating of 74 dBA, the generator is one of the more quiet of the generators of similar power. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA13000EFI, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
  • The WGen12000, offering a run time of around 11 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Powerhorse 13000ES, which is able to run for around 15 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. At an estimated fuel consumption of 0.95 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA13000EFI. With a fuel consumption of as little as 0.78 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 10000-14000W generators, the Westinghouse WGen12000 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

About Westinghouse

The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators. Portable generators – the main product of the Outdoor Power Equipment branch of Westinghouse – used to be manufactured by Westpro Power Systems, which was bought in 2016 by Midwest Equipment. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, several sources report that they are in many cases manufactured in China.

Warranty Information

The Westinghouse WGen12000 is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.
