Zoom on the Westinghouse WGen9500
In summary, the Westinghouse WGen9500 is a powerful portable generator especially useful for:
- Prudent homeowners who want a backup power source in case of a power outage
- Professionals in need of safely powering high-intensity work or lighting equipment
- 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 Westinghouse WGen9500's engine, 457 cc (13.5 hp) Westinghouse OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 9,500W and reaches a peak wattage of 12,500W.
With a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the WGen9500 can also be remotely started (key fob included).
With a fuel capacity of 6.6 gallons, the WGen9500 may run for up to 17.5 hours with a full tank (fuel consumption around 0.55 GPH).
The WGen9500 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<23%).
The control panel includes the following 6 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.
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, since the WGen9500 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.
Westinghouse's ST Switch Outlet
The WGen9500 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 WGen9500 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 W26.5 x H26.5 in, the conventional, open frame design of the Westinghouse WGen9500 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 208 lbs make it incredibly difficult to manually lift and transport. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
The control panel of the WGen9500 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
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 automatic low oil shut-off and an overload protection (circuit breaker), 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 WGen9500 also comes with several accessories, including: key fob, oil, battery charger, funnel and tool kit. An official storage cover is also available, as a separate purchase.
The Westinghouse WGen9500 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 WGen9500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500 compare to generators of similar power (between 9000 and 10000 W).
- Weight-wise, the Westinghouse WGen9500 has only 208 lbs, which renders it one of the lighter generators which produce 9000 to 10000 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PG12000B, with a dry weight of only 205 lbs.
- Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its 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.
- With a run time of around 12 hours at 50% load, the WGen9500 has one of the higher run times, compared to its similarly powerful peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Powerhorse 13000ES, as it provides around 15 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. At an estimated fuel consumption of 0.55 GPH (gallon per hour) at 50% load, this generator is one of the most fuel efficient units within its wattage category.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 9000-10000W generators, the Westinghouse WGen9500 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Several accessories included
- GFCI Outlets
- Remote start
- Smart Switch Ready
- Lightweight for its kind (208 lbs)
- High run time
- Fuel efficient
- Acceptable noise (74 dBA)
The Westinghouse WGen9500 doesn't have any notably low specs.
