Zoom on the Westinghouse WGen9500DF
In a nutshell, the Westinghouse WGen9500DF is a powerful portable generator mostly geared towards:
- Small homeowners in search of a full power backup solution
- Professionals who want to ensure that a power failure will not prevent them from working
- Homeowners in need of an emergency backup power for their essentials
- RV travellers who wish to upgrade their experience to another level
Power & Run Time
The dual-fuel technology of the Westinghouse WGen9500DF allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 9,500W and a starting wattage of 12,500W. If propane-powered, it gives 8,500 rated watts and 11,200 starting watts.
At a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included). For additional convenience, the WGen9500DF may also be remotely started (key fob included).
As for its running time, the WGen9500DF, along with its 6.6 gallons fuel capacity, can run for up to 12 hours with a full tank filled with gasoline (fuel consumption around 0.55 GPH). If propane is used, it can operate for around 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).
The WGen9500DF is unsuitable for the powering of sensitive electronic devices due to its high THD (<23%).
The control panel features the upcoming 6 AC outlets:
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 WGen9500DF 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 WGen9500DF 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 WGen9500DF 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 WGen9500DF has a conventional, open frame design, of the following dimensions: L27.2 x W26.1 x H26.5 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough 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 211 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 control panel of the WGen9500DF includes a convenient meter, which displays 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.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Westinghouse WGen9500DF also comes with some accessories: oil, battery charger, propane hose, funnel, tool kit and key fob are included. The official storage cover and running cover are also available, as separate purchases.
The Westinghouse WGen9500DF 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, so it is adequate for use in forested areas.
The Westinghouse WGen9500DF versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500DF compare to dual fuel generators of similar power (between 9000 and 10000 W).
- As its weight is 211 pounds, the Westinghouse WGen9500DF falls in the expected weight range of the dual fuel devices in the 9000-10000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Westinghouse iGen11000DFc, with a dry weight of only 187.4 lbs.
- As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Westinghouse iGen11000DFc. With just 64 dBA, it is one of the most quiet devices in this power range.
- As far as autonomy is concerned, providing around 8 hours of runtime with a full tank at a 50% load, the WGen9500DF falls into the low end in comparison with other dual fuel devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen11000DFc, as it provides around 12 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. As this generator uses an estimated 0.83 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.66 GPH, the Westinghouse iGen11000DFc is a device you could look out for.
Here's a list of the most popular specific comparisons:
As you can see from these interactive charts, when compared to other 9000-10000W dual fuel generators, the Westinghouse WGen9500DF is on the average side of the price range.
