Westinghouse 9500-Watt Generator Review: WGen9500 vs WGen9500DF

Westinghouse, a common name in the American power equipment world, has been in business for over 130 years. With such a long history behind them, it comes as no surprise that they are the go-to brand for many people shopping for a generator.  The company prides itself on its success which comes through in the statement, “Driving innovation for over 130 years, Westinghouse has been there for our history’s biggest moments.” From a humble beginning in 1846 to introducing the first-ever airborne surveillance radar system in 1977, Westinghouse has been with the Americans for every minor and major turn of their lives. Westinghouse has been there for all the big moments. Ranging from a power outage to capturing the first moonwalk for viewers on the earth in 1969. It’s safe to say that the company has always held its end firmly. NASA officially awarded Westinghouse the contract for the lunar TV camera in the 1960s, which in itself is impressive.

To make a long story short, Westinghouse currently manufactures hundreds of products in different categories. The company provides us with top-line generators, pressure washers, lawn and garden tools, and various other outdoor power equipment.

Westinghouse generators are in a class of their own. Westinghouse is the brand to opt for if you are looking for outstanding, reliable, durable, and affordable generators for power outages. Westinghouse generators are also ideal for RVs, worksites, fairs, festivals, or any other purposes. The name has become such an institution over the years that many trust it blindly (and they can, because the range is reliable and affordable to boot). Today, we will review and compare two of Westinghouse’s best generators in the medium-sized (9500 watts).

WGen9500 and WGen9500DF (dual fuel) will be the center of our discussion in the article to follow. This comparison will discuss the significant features, usability, differences, pros, and cons of each machine. Before we get down to the comparison part, let’s check out the practical uses for a 9500-watt generator.

When is a 9500-watt generator the best choice?

When faced with the following power problems, only a 9500-watt generator will suffice.

Power Outages

When the power goes out at your home because of a regular outage or an emergency, the first thing that comes to mind is how long you will be plunged into darkness. Different thoughts start to creep into your mind; will the food in the refrigerator rot before the power comes back on? Will you be able to sleep tonight without AC/heater? Will the well pump/water filters continue to operate? Are you safe because of no connectivity? Is the security system up and running? Can you complete your work assignments on time? For all these power needs and to run many other appliances for a medium to large household, a 9500-watt generator is the best option. It has enough juice to keep you going and provides an impressive runtime. The Westinghouse 9500 watts generator is a reliable machine for catering to all of these needs and more. 

Worksites

It’s an unfortunate reality that a lot of worksites don’t offer grid power. Worksites also suffer power outages frequently. In such a situation, you need alternative power to keep your tools running and your project on track. Keeping tools and equipment up and running during a power outage is particularly important when deadlines need to be met. Westinghouse’s 9500-watt generators are exactly build to do this. Either it is running on gasoline or propane, the unit provides enough power to manage your small and medium tools such as grinders, mixers, saws, drill machines, and cutters.   

RVs

Millions of people own RVs in the US and that means that millions of people have the need for alternative power. While you travel in an RV, you need to make sure that all your appliances stay up and running for the duration of your trip (especially when you are stopped somewhere for several days). You cannot use RV’s power to run your appliances – if you do, you will end up with a flat battery. A generator is the best choice to power your RV’s machines when you don’t have shore power. Westinghouse 9500-watt generators are RV-ready machines that can be quickly plugged into your RV’s AC system, and you can run all the appliances in your RV without any worries. With this unit, you won’t need to make compromises while running the fixtures in your RVs.

When to Avoid this Machine?

The uses of generators are countless, but there are instances where they are to be avoided. Keeping this in mind, here are some situations when you can’t make use of 9500-watt generators, such as camping, spending time on the beach, holidaying on boats, and tailgating. You don’t need a lot of power for any of these experiences, but you do need some power. All you need is a lightweight generator with a power range of 1000-3000 watts. An inverter generator is an ideal solution. Imagine a 200-300 pound generator on a boat or a noisy unit at tailgating or campsites. We don’t want you to disturb yourself and the peace of others. It will be practically impossible to manage, and you will be spending all your time dragging and operating the machine instead of focusing on the fun you should be having. Hence, it is better to stay away from big machines in such circumstances. If you don’t want to make a noise and don’t want the hassle of dragging a hefty machine around, do not opt for a 9500-watt generator.    

Westinghouse 9500-Watt Generator Review: WGen9500 vs. WGen9500DF

This section of the review will critically evaluate and compare each machine’s major features and explain how they fare against each other.

Fuel Type and Power Output

WGen9500

WGen9500 runs on gasoline and provides 12500 starting watts and 9500 running watts. The power outage is enough to run major appliances in your home like AC/heater, well pumps/sump pumps, refrigerator, microwave oven, stove TV, laptop and phone chargers, fans, and lights. You may face some issues if you try to run all of these appliances together. If you start motorized appliances (with higher starting wattage) one by one, you can adjust more loads on your generator, which is quite convenient. For worksites, this power is enough to run most of your tools. It will also give you a reliable power backup for your RVs.      

WGen9500DF

It is a dual fuel machine and can be run on gasoline and propane – the choice is yours. Dual fuel machines give different power outputs on gasoline and propane, so it’s best to know what to expect from each fuel type. Both the fuel types differ in some other aspects as well, but we will get to that later. The WGen9500DF delivers 12500 starting and 9500 running watts on gas. On propane, it produces 11200 peak wattage and 8500 rated wattage. The starting and running wattage is lower on propane, which is to be expected. Propane offers a lower running wattage because gasoline has a better burn rating than propane. This essentially means that it has better combusting properties. When the generator is running on propane, you may not be able to run as many appliances as you could if you were running the machine on gasoline, but it is still impressive and offers decent output. You may need to switch out some appliances as you go to make space for others, but a dual fuel machine will keep you going when you don’t have gasoline. A dual fuel machine comes in handy at times of natural emergencies, infrastructural problems, or gas shortages in your neighborhood.   It’s a good all-rounder.

Tank Capacity and Runtime

WGen9500: The Machine gives a runtime of up to 12 hours on a full tank. The tank has a maximum capacity of 6.6 gallons. It means that if you fill the tank right up and the running load on your generator is around 4500 watts, then you can get a backup time of 12 hours.  For most people, this is more than enough. You won’t need to get up in the middle of the night to refuel the generator, which is convenient and provides added peace of mind. At worksites, this runtime is enough to navigate a complete work shift of 8-9 hours with a 50% load.  Presumably, this is sufficient for most work sites.

WGen9500DF: The runtime on gasoline is the same as compared to gasoline. On propane, the runtime varies depending on the cylinder’s size attached to the unit. On a 20lb propane tank, this machine will run for approximately 7 hours on a 50% load. If you connect a 40lb propane cylinder, you will get 14 hours runtime out of the machine. However, it is suggested to run the machine for a maximum of 7-8 hours continuously. You need to turn the machine off from time to time as it needs some rest to cool down. Over-running the machine can lead to burnout or lead to more maintenance requirements.

Engine Specifications

WGen9500 and WGen9500DF: The engine in both of these models is the same. You get a 457cc 4-stroke OHV (overhead valve) engine. The engine is constructed with a durable cast iron sleeve and will not let you down in harsh working conditions. The fuel type also won’t affect the starting ease, which provides much-needed peace of mind for users. The engine won’t give you trouble in cold weather, and your generator will be up and running in a couple of seconds. There is one flaw with this particular range that you should be aware of, and that is that the engine is heavy and increases the total weight of the unit. However, while the weight of the machine is inconvenient, it also adds to the machine’s durability and reliability, and thus it is worth it. Some extra pounds won’t hurt if it means you are getting value for your money and longevity.      

Dimensions, Weight, and Portability

WGen9500 and WGen9500DF: These are two more models where there is no difference in the engine. The machines weigh 220 lb (98 kg) and measure 27.2L x 26.1W x 26.5H inches. It is a slightly bulky machine, but the included wheel kit and handle make it easier to move around, so the size and weight aren’t really a factor. The never-flat wheels are big and heavy-duty and are way better than ordinary wheel kits with other brands. The handle has an ergonomic design and is covered with soft rubber to provide you a comfortable grip. Hauling the machine here and there is not a terribly inconvenient task. You get two solid base points to keep the machine steady while it is running. One healthy adult can manage both models with ease. You may face some issues while moving this machine uphill or on a rough patch, so keep that in mind if you plan to use the generator in such conditions.  

Outlets

WGen9500 and WGen9500DF: The outlets almost stack up the same for both the Westinghouse 9500-watt generator variants. Both have GFCI outlets. When it comes to the outlet option, you get two duplex 120V 5-20R, one 120/240V L14 30R, one 120/240V 14-50R, and an ST switch. All these outlets are protected with rubber covers which adds to user safety. The WGen9500 (gasoline) model also offers two USB ports which are missing in the WGen9500DF variant. Both the machines are transfer-ready and RV-ready models.  

Other Features

WGen9500 and WGen9500DF: You get remote starting in both of these models along with electric and recoil starting mechanisms. Both models are loaded with a built-in fuel gauge, safety features such as automatic low oil shutdown, automatic voltage protection, and overload protection. You get VFT data centers to help you keep track of volt output, frequency, and total running hours to keep track of maintenance needs. The generators offer load protection but lack overload indicators, which could be annoying for some users. With these models, you get an oil bottle, oil funnel, spark plug wrench, remote, battery float charger, and variants. A propane hose is included in the DF variant.  

Operation

WGen9500 and WGen9500DF: The basic operating process is the same for both of these generator variants. However, WGen9500DF allows you to select the fuel type with a simple to operate knob. To run this machine, you have to make sure that you set it up solid flat ground, fill gas or connect propane cylinder and turn on the machine. Once the generator is up and running, you can then connect the loads for your respective needs. It’s important to follow the correct start up process.

Maintenance and Safety

WGen9500 and WGen9500DF: The maintenance and safety needs for both of these units are the same. You have to ensure the following.

• Never store your generator with fuel in the gas tank or use a fuel stabilizer if there is gas in the tank.
• Test run your generator for 30-40 minutes every 15-20 days when not in use for more than a month or two.
• Store your generator in a safe, dry place and protect it with a generator cover.
• Make sure you have backup spark plugs, engine oil, oil and air filters, and fresh fuel for your generator.
• Run your generator outdoor in a properly ventilated area.
• Always use fresh gas and never overload the machine.
• Maintain a safe distance of 15 feet from the sitting area and never move/refuel a hot unit.
• Always use a transfer switch to connect your generator to your home panel.
• Never connect the generator to a wall outlet.
• Make sure that you use high-quality power extensions with your machine.
• For WGen9500DF, regularly inspect the propane hose and ensure that it is properly connected before releasing the cylinder valve.
• Follow the user guide for details on the maintenance and safety needs of your machine.

Price and Running Cost

WGen9500 and WGen9500DF: The WGen9500 is cheaper than the WGen9500DF. However, WGen9500DF gives a low running cost, making it the cheaper option in the end. Dual fuel generators are technologically advanced, and thus you have to pay more for them. Propane is cheaper than gas, but it gives low output power and low runtime, so is it really cheaper when running a generator? If you have a dual fuel generator, the best way to solve this dilemma is to use gasoline when you need more power for big machines. If your power needs are not high and you want your generator to run economically, propane is an excellent option.

Summary

Pros and Cons

Accessories for WGen9500 and WGen9500DF

Generator Cover: A generator cover comes in handy when you store your generator for a long time. It keeps the Machine safe from dust, water, dirt, UV damage and keeps small animals like rats, cats and raccoons away. This cover fits perfectly on all the Westinghouse units up to 9500 running watts. It comes with a drawstring for a tight and secure fit.

Generator Cord: A generator cord is needed for outdoor use. When you are at a worksite, you can’t move your generator with your tools. Secondly, it is not safe to keep your generator so close to your workspace. In such a situation, power cables come handy. These cables also allow you to run the appliances directly on the generator. We suggest you go with Westinghouse cords to keep everything safe and ensure that the warranty agreement is not breached.     

Gasoline vs. Propane: A Comparison of both Fuels

When you are stuck selecting between a single fuel and a dual fuel generator, a comparison of both fuels will help clear some confusion in your mind. The most important factor is output; we have already highlighted it in detail above. Here, we will compare some other vital factors for you.  

Runtime: When we talk about a big generator such as Westinghouse’s 9500, the propane runtime is lower than gasoline. However, for smaller units, less than 5000 watts runtime on propane and gas is almost equal. To get an increased runtime with your dual fuel generator, you can do a little trick. Fill the gas tank and keep a propane cylinder ready. First, you can run the generator on gas and then connect propane. In this way, you can avoid downtime, and you don’t need to wait for the generator to cool down for refueling.  

Availability: Under normal circumstances, gas and propane are readily available without any issues. However, during emergencies and infrastructural problems, gas becomes challenging to find. In such situations, stored propane can be used to power your homes.

Shelf Life: The reason propane can be used during emergencies is that it has a long shelf life compared to gasoline. On average, gas goes bad in 3-4 months, and then you will have to replace the gas stock. If you use old gas, the generator will start troubling you and will develop mechanical issues. On the other hand, propane can be stored for 10-30 years without any worries. However, you need to take care of a couple of things here. The cylinders must be in good health, and the valves must be checked regularly.

Safety: Propane is a safer fuel option compared to gasoline. It is odorless, non-toxic, and is produced as a byproduct. It burns cleaner than gasoline and diesel. If the tank was ever to leak, the risk of contamination is very low. However, it is flammable. So, care must be taken while working around it. It must be stored in a well-ventilated area. There are no risks of spillage with propane compared to gas. Handling gas tanks and keeping them away from the fire is comparatively difficult than handling propane cylinders. However, propane cylinders are heavy because of metal construction.    

Which Machine is Best for Me? WGen9500 or WGen9500DF

The answer to this question depends on your usage pattern. If you live in a severe climatic zone, then we advise that you go with Wgen9500DF. A dual fuel machine will keep you going when one fuel runs out. Similarly, if you live in a remote area where gas shortage is frequent, go for dual fuel generators. If you are a contractor and can’t afford downtime for refueling, buy 9500DF.  

For occasional users and DIY people, Wgen9500 will do the needful. It is also best for RVs and small-time power outages. If your area is in a safe climatic zone and you only experience routine power outages or fluctuations, a single fuel generator is good for you. Wgen9500 is also excellent for running tools in home and worksites.  

Comparison with other Brands in the same Power Range

DuroStar DS10000E and DuroStar DS10000EH

DuroStar, another leading brand, offers generators in almost the same power range. You have the option to buy single fuel and dual fuel variants. The outlets, control panel features, portability, and other features are almost the same. Durostar is slightly cheaper than Westinghouse. Please keep in mind that the engine power in DS10000 is the same as WGen9500, but it gives a higher output (500 watts more) than WGen9500. It means that Durostar’s engine is a bit underpowered. Another area is where WGen9500 aces DS10000 is warranty. DS10000 comes with a 1-year warranty.

Champion Power Equipment 100891

Another generator in the same power and price range is Champion is 7500-watt dual fuel generator. Champion is not offering a single fuel generator in this category. So, if you want a gasoline unit, Champion is not your brand. Its dual-fuel variant has a starting wattage of 9375 watts and a running wattage of 7500 watts on gasoline. It lags behind Westinghouse here because WGen9500 comes with a starting wattage of 12500 watts on gasoline. Its power output on propane is also lower than WGen9500DF. It offers a 3-year warranty. The outlets, safety features, and control panel options are almost the same.   

Generac 7676 Portable Generator

Another model which competes with WGen9500 is the Generac GP8000E gasoline generator. Generac is known for producing durable and rugged portable generators. Its noise level is lower than WGen9500 and WGen9500DF. However, it lacks a remote starting mechanism. The warranty period is of 3 years. This machine outnumbers WGen9500, DS10000, and Champion 100891 for runtime.

FAQs

Final Words

We hope that you are now in a position to decide which generator is best for you. One thing is for sure, Westinghouse is one of the most trusted generator brands. The Wgen9500 or Wgen9500DF are two of its best machines to date. They won’t let you down at the time of need.
