Zoom on the Westinghouse WGen9500
In a nutshell, the Westinghouse WGen9500 is a powerful portable generator mostly geared towards:
- Small homeowners in search of a full power backup solution
- Professionals in need of safely powering high-intensity work or lighting equipment
- Homeowners in need of an emergency backup power for their essentials
- RV travellers looking for even more independence
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Westinghouse WGen9500's core is the 457 cc (13.5 hp) Westinghouse OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 9500W and a peak wattage of 12500W.
The generator features a simple traditional pull-start mechanism and also 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). For additional convenience, the WGen9500 may also be remotely started (key fob included).
Thanks to a fuel capacity of 6.6 gallons, the WGen9500 can operate for up to 17.5 hours with a full tank (fuel consumption around 0.55 GPH).
The quite high THD (<23%) of the WGen9500 makes it unsuitable for powering sensitive electronic devices.
The control panel provides the upcoming 6 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.
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 it features a twist-lock L14-30R receptacle, the WGen9500 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
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. The generator is designed for ideal use outdoors and in rough environments.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 208 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.
The WGen9500 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
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: battery charger, oil, key fob, 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, making it usable 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.
- This generator has a somewhat average expected noise for its power range, rated at 74 dBA. 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.
- 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. 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 Powerhorse 13000ES, with 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. This generator is one of the most fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.55 GPH (gallon per hour) at 50% load.
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.
