Description

Zoom on the Westinghouse WGen9500DF

In summary, the Westinghouse WGen9500DF 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

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 WGen9500DF in use

The Westinghouse WGen9500DF

Thanks to its dual-fuel technology, the Westinghouse WGen9500DF delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9500W and a peak wattage of 12500W. When propane-powered, it has 8500 rated watts and 11200 peak watts.

At a noise rating of 73 dBA (just slightly more noisy than a shower), this generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the WGen9500DF can also be remotely started (key fob included).

With a fuel capacity of 6.6 gallons, the WGen9500DF can operate for up to 17.5 hours using gasoline (fuel consumption around 0.38 GPH), or for up to 11 hours (on a 20 lbs tank - propane consumption around 0.43 GPH) using propane.

Since the WGen9500DF has a somewhat high THD (<23%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the upcoming 6 AC outlets:

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

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

Picture of the ST Switch outlet

The 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.

Portability

The Westinghouse WGen9500DF has the following dimensions: L27.2 x W26.5 x H26 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 220 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by its wheel kit (⌀10") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The WGen9500DF's control panel

The WGen9500DF's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, 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 WGen9500DF also comes with several accessories, including: propane hose, key fob, tool kit, battery charger, oil and funnel. An official storage cover is also available, as a separate purchase.

Emissions

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, which makes it suitable for use in forested areas.

Product Videos

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 generators of similar power (between 9000 and 10000 W).

  • As for its weight, the Westinghouse WGen9500DF weighs only 220 pounds, making it one of the lighter generators in the 9000-10000 rated wattage category. In terms of weight, one of the champions in their power range is the Rainier R12000DF, standing at just 196 lbs.
  • As its lowest possible noise is rated at 73 dBA, this generator qualifies as one of the more quiet of the products of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the A-iPower SUA12000ED with only 69 dBA.
  • With a run time of up to 17.5 hours at 25% load, the WGen9500DF has one of the highest run times, compared to its similarly powerful peers.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about 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 0.38 GPH (gallon per hour) at 25% load.

Price comparison

As you can see from this interactive chart, when compared to other 9000-10000W generators, the Westinghouse WGen9500DF 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.

Is it safe to charge/run delicate equipment such as TV, computers, cell phones? (Asked June 15, 2020)

THD should be under 5% to safely run devices that contain sensitive electronics. This unit's THD is <23%, and thus, too high.

does this gen have idel control? (Asked September 06, 2020)

This unit does not have an idle control feature.

Can it also be converted to natural gas? (Asked September 21, 2020)

There are no official conversion kits.

I understand that you can’t run computers etc. But, is it okay to charge a battery powered laptop since the charger is plugged in to just charge the battery as long as you don’t use the laptop while its charging? (Asked October 21, 2020)

Not if you value the circuitry of your charger. Your laptop works on DC, not on AC.

If run through a 50 amp transfer switch and breakers can you safely use tv, charge cell phones, computers? (Asked November 03, 2020)

A transfer switch does not clean power, it just transfers it.

Does the Westinghouse 9500 have an oil filter? An oil filter I can change when I change oil? (Asked November 03, 2020)

The WGen9500DF does not have an oil filter.

Is it safe to use with computers, laptops, cell phones, etc. if those items are plugged into a high end APC UPS unit in between this source? (Asked November 08, 2020)

It would have to be a double-conversion online UPS (opens in a new tab), which will first convert AC to DC, then DC back to AC.

how to remove bonded neutral (Asked December 10, 2020)

You can follow Westinghouse's guidelines (opens in a new tab) or refer to our article on neutral conversion.

Can this generator be outside during winter snow storms, How low the temperature can be in order to be outside? to storage can be in a non heated garage in winter time? (Asked December 17, 2020)

The unit is rated for operation between 5°F and 104°F. In case of exposure outside of this range during storage, it should be brought back within this range before operation. You may also read our article on rain and snow operation.

    WGen9500DF (Dual Fuel)

    This is an outstanding generator. First, it was difficult to find it in stock at any of the big-box stores over the course of a couple months, let alone Amazon or other smaller vendors. Most of the reviews I read were overwhelmingly positive, and clearly this is an extremely popular generator. Now that I have tested and proven it – – I understand why.

    I ordered it mid-April and it arrived first week of June. The generator was in its original cardboard packaging secured by two typical plastic straps and was without any damage or perforations. Upon opening and visual inspection, the contents were present and securely packaged as described by Westinghouse (oil, tool kit, propane hose/regulator, remote FOB, etc.). The manufacturing and serial number information states “Made in Vietnam”.

    I hired a local, reputable electric company to install a 50-amp generator receptacle outlet, circuit, and interlock kit on my main breaker panel (required by city code) the day after the generator’s arrival. I prepped the genny prior to the install by following the Owner’s Manual instructions and had no problems (feet, wheels, battery, or oil). It did need just a bit more oil (maybe 3-4 oz.) to top off the oil fill-line. I selected propane for its first fuel, ran it for 5 minutes and then switched to gas. Both were flawless. My wife is able to easily move it as well. I was now ready for the electricians to install the designated outdoor receptacle/circuits/breaker and interlock kit the following day.

    Fantastic! Even my electricians were impressed with the features and performance of this generator. It powered my 3.5 ton central A/C and a few other nominal circuits. However, the A/C is not my primary intent, as that was only to see if it could…and it did. I have a portable A/C & heater that I will plug if needed, rather than using central A/C. I also researched each of my circuits to ascertain their wattage usage in order to designate the circuits I would power on for the generator. I printed that spec-sheet and it is affixed to the inside breaker panel for reference when using the generator power. With proper maintenance, I expect to get many years of reliable service from this beast. My previous generator was a 6500-watt electric start which I gave to a friend, and it is still performing well after 12 years. I am very pleased with this WGen9500DF and highly recommend it. Best wishes!

    Initially bought this about 1.5 years ago. Arrived in good shape and would not start. Turns out the start switch on the panel was faulty based on my testing because it would pull start AND the remote start worked just fine. I called customer service and they offered to send me a new switch. When it arrived I realized pulling that panel out was a pain and I did not want to mess up the wiring in any way so they authorized repair center to do work. I have to haul it there (in my city) which was a pain because this is heavy. They repaired switch and it worked fine. Always easy to start, worked on both fuels. Was happy. Up until then I only used 20A outlets and the 30A outlet. I wired in backup to my house and switched to the 50A outlet and only one side was hot. The outlet was not functioning! I did not find this out until about 1 year into ownership and customer service said “tough luck”. I told them it had just been serviced and perhaps the service center damaged the wiring? Still no help. I decided to tear apart panel myself and sure enough found a connecter was disconnected for a logic board.I put it together an now works fine. So, overall this is a lot of power and seems to work well but only after I diagnosed it and messed with it myself. Quality control and customer support could be better. Test EVERYTHING when you buy it thoroughly and I bet they will stand by it, but after 1 year even probelms that they created they will not help with.

    + PROS:
    • Apparent nice build quality, useful outlets, initially had good customer service, reliable start
    - CONS:
    • Poor quality control, service centers with questionable quality, and then abandoned by customer service.
