Description

Zoom on the Westinghouse WGen9500DF

In a nutshell, the Westinghouse WGen9500DF is a powerful portable generator mostly geared towards:

  • Homeowners who wish to power almost all appliances in their house under any circumstances
  • Professionals who want to be able to deliver results, even during a power failure

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 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.

With a noise rating of 73 dBA (just slightly more noisy than a shower), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included). For additional convenience, the WGen9500DF may 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.

The quite high THD (<23%) of the WGen9500DF makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel provides the upcoming 6 AC outlets:

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

Due to the featured twist-lock L14-30R receptacle, the WGen9500DF is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

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.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 220 lbs. 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.

Features

Panel of the Westinghouse WGen9500DF

The WGen9500DF's control panel

The control panel of the WGen9500DF includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Westinghouse WGen9500DF also is packed along with the following accessories: oil, key fob, battery charger, funnel, propane hose and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The Westinghouse WGen9500DF is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate 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 far as its dry weight is concerned, the Westinghouse WGen9500DF weighs just 220 pounds and thus, it is one of the lighter 9000 to 10000 rated wattage generators. Regarding dry weight, one of the champions in the same power range is the Rainier R12000DF, with a dry weight of only 196 lbs.
  • Since this generator is rated for a lowest possible noise of 73 dBA, it can be considered as one of the more quiet of the products generating similar 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.
  • The WGen9500DF provides one of the highest run time among similarly powerful devices, reaching up to 17.5 hours at 25% load.
  • 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. With an estimated gasoline consumption of 0.38 GPH (gallon per hour) at 25% load, this generator is among the most fuel efficient of the products in the above-mentioned wattage range.

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.
