Description
Zoom on the Westinghouse WGen9500DFc EFI
In short, the Westinghouse WGen9500DFc EFI is a powerful portable generator adequately designed for:
- Homeowners who wish to power almost all appliances in their house under any circumstances
- Professionals in need of safely powering high-intensity work or lighting equipment
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
With its dual-fuel technology, the powerful and versatile Westinghouse WGen9500DFc EFI provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 9,500W along with a peak wattage of 12,500W. While propane-powered, it provides 8,500 rated watts and 11,200 starting watts.
The generator features a manual recoil starter system and also a simple and elegant electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a shower). For additional convenience, the WGen9500DFc EFI may also be remotely started (key fob included).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
Regarding its running time, the WGen9500DFc EFI, with a 6.6 gallons fuel capacity, can operate for up to 15 hours with a full tank of gasoline (fuel consumption around 0.44 GPH). When using propane, it can run for around 8.7 hours (on a 20 lbs tank - propane consumption around 0.54 GPH).
Since the WGen9500DFc EFI has a high THD (<23%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel includes the following 6 AC outlets:
Additionally, it offers 2 DC outlets: there's two 5V USB ports (USB-A) enabling convenient charging of devices like mobile phones and tablets.
Because the WGen9500DFc EFI is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.
Westinghouse's ST Switch Outlet

The ST Switch outlet
The WGen9500DFc EFI 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 WGen9500DFc EFI 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
At L27.3 x W20.6 x H22.5 in, the standard open frame design of the Westinghouse WGen9500DFc EFI delivers stability alongside easy maintenance access to components and good air cooling. The design is ideal for rough environments and demanding outdoor use.
Though weighing 221 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
Features
The WGen9500DFc EFI 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. To offer you even more control and easy operation during nighttime, the panel is LED-lit.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
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.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Westinghouse WGen9500DFc EFI is bundled with additional accessories: battery charger, tool kit, propane hose, key fob, funnel and oil.
The Westinghouse WGen9500DFc EFI versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WGen9500DFc EFI compare to dual fuel generators of similar power (between 9000 and 10000 W).
- At a dry weight of 221 pounds, the Westinghouse WGen9500DFc EFI is one of the heavier dual fuel devices which can produce between 9000 and 10000 running watts. If you are mindful of weight, the Westinghouse iGen11000DFc is among the top contenders in this power range, with a dry weight of 187.4 pounds.
- When comparing it to devices with a similar running wattage, this generator's lowest noise level of 74 dBA puts it alongside the noisier units. If noise emissions are important to you, one of the least noisy generators of this power range is the DuroMax XP11000iH with only 61 dBA.
- As for its autonomy, the WGen9500DFc EFI, with an autonomy of up to 15 hours at a 25% load, is placed on the low end among the generators of its kind. If runtime is a priority for you, the DuroMax XP11500EH stands out as one of the generators with the longest run time in its power range, providing up to 20 hours of continuous use.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.44 GPH (gallon per hour) at a 25% load. To prioritize fuel savings, we advise considering the DuroMax XP11000iH, which stands out for its gasoline efficiency, consuming just 0.39 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 9000-10000W dual fuel generators, the Westinghouse WGen9500DFc EFI is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
