Last Updated on October 17, 2022 by Manager Access

Westinghouse WPro 8500 Watt Generator review
When you need reliable power on the go, a quality portable generator is just one of those must-have pieces of equipment.

One highly rated option is the Westinghouse WPro8500 Super Duty Industrial Generator.

It is both efficient and utility-friendly and would be a great fit for anyone who needs a well-designed and powerful yet fine-tuned portable 8500 Watt generator.

Below, we will take a look at its features, specs, and reviews.

About the WPro8500 Inverter

This tough super duty portable generator was built to be versatile and convenient.

It can be utilized for professional applications, personal use, and a wide variety of industrial situations.

The Wpro 8500W has been solidly constructed with quality materials and would be a good option for many different jobs. With a cast iron sleeve and forged internal components, this generator is up for just about anything.

The 457cc 4-Stroke OHV Westinghouse Engine is capable of running for a decently long time.

You will get around 17.5 hours on a full workday from its gas tank which holds 6.6 gallons (25 L).

The built-in fuel gauge lets you easily see how you’re doing on gas as well.

It has less than 5% Total Harmonic Distortion, making it a fantastic option for powering sensitive tools and electronics.

This unit is 100% OSHA, EPA, and CARB-Compliant and has been backed by a Westinghouse 3-Year Warranty.

It also comes ready to use out of the box, which includes Oil, an Oil Funnel, the Tool Kit, and an in-depth User Manual.

Other features include the Full Panel GFCI with (4) 120V 20A 5-20R Standard Household Outlets, (1) 120V 30A L5-30R, (1) 120/240V 30A L14-30R, and (2) 5V USB ports.


• 8500 Running Watts
• Panel GFCI with (4) 120V 20A 5-20R Standard Household Outlets
• Super Duty 13.5 HP 457cc OHV 4-Stroke Westinghouse Engine
• OSHA, EPA, and CARB Compliant

Noise Levels: Just how noisy is it?

While there is no such thing as a quiet open-frame industrial generator, if noise is an important factor to you on a job site, this generator may be a good option.

You can’t really hear it in a shop or building if the doors are closed, which is saying something considering the power output and mechanical durability of this machine.

Personal use is even a viable possibility with this unit, it isn’t unreasonably loud and could be utilized in a home shop or garage.

This is hands down one of the quietest high-power output gas generators out there.

Especially when you consider that it has been created for working applications and industrial use.

You won’t need to use earplugs while working around it and it’s considerably quieter than a gas mower.

Sound Specs:
• Ear plugs not needed
• Quiet enough to use in a residential area
• Comparatively, one of the quietest open-frame industrial generators out there

Gas Consumption & Capacity

Fuel efficiency is an important factor to consider with any generator.

The Westinghouse WPro8500 offers standard run times of around 17.5-hours on a 6.6 Gallon fuel tank.

The tank comes with an easy-to-read built-in gauge for added user convenience.

It doesn’t run on propane right out of the box, but there is a conversion kit that you can buy if propane is your preferred fuel type. Find out more about propane inverters in my post about dual fuel generators.

All in all, this is a pretty efficient option that is convenient to use.

Fuel Specs:
• Runs on gas
• 17.5-hour run time
• 6.6 Gallon Fuel Tank
• Efficient and convenient
• Built-in fuel gauge

Service, Manual & Warranty

The way that a product operates in the long run, how the brand holds up service-wise, and its warranty, are all important factors to consider when buying a generator.

Westinghouse has a reputation as being a trusted brand with quality products.

While this is a quality product that doesn’t have any issues, if it does have problems, you will have to check to be sure that you’re well within the conditions of the warranty it comes with.

Some customers have complained about the untrained and rude employees that you get on the other line if you call in with issues.

That being said, the 3-Year Warranty is decent and the unit doesn’t have very many reported issues overall.

The user manual is also pretty detailed and easy to understand, you can see it here.

As far as assembly goes, you just have to hook up the battery and put on the wheels.

It comes pretty much ready to use out of the box and is a “Plug and Play” option that can be put to use quickly and easily.

So, the brand and product are good, the manual is easy to read, and it has a good warranty.

However, the call-in service center is pretty aggravating, according to consumer reviews.

Online Customer Reviews and Ratings

Knowing what real-life users are saying is an important factor to consider as well.

The Westinghouse WPro8500 Super Duty Industrial Portable Generator has overall positive consumer reviews.

It has mostly positive reviews at the time of this guide, with over 1,000 reviews on Amazon.

Users reported that in its respective class, it was one of the best values.

They claimed that it was quiet when compared to other similar options and also very efficient.

Some reviewers also said that the shipping was fast and that this product was well-packaged.

It’s reportedly quick and easy to set up and very reliable.

However, there were some negative reports about the customer service offered by Westinghouse.

Still, overall, buyers seemed to be very satisfied with the performance, efficiency, sound output, and durability of this generator overall.

Potential Problems & Known Issues

There aren’t really any recurring issues with this generator. The only issues we saw had to do with propane, price, and customer service.

It won’t run off of propane right off the bat.

If you’re going to be using it in extreme temperatures, you may want to get a conversion kit.

Also, it is a bit more expensive than other generators, but in its class, it’s still a really great value.

The biggest issue reported with this generator is its included customer service.

It’s pretty apparent that Westinghouse needs to work on its call center training.

Other than that though, this unit has relatively few complaints.

My Opinion: Should you buy it?

Deciding whether or not a product is worth the money you spend on it can be tricky; with the Westinghouse WPro8500 Super Duty Industrial Generator, I feel like the price and quality balance out pretty well.

It has plenty of impressive features, is convenient to use, and above all, is designed with care, durability, and quality.

Customers seem to find that it’s a great option and it has a few downsides.

However, if you aren’t in need of a professional-grade generator, you could probably save some money and go with something cheaper to get most small jobs done.

Still, if you need something that’s been crafted with quality and care and can also be used for sensitive electronic tools, this is a very good option that is well worth the consideration of many people in industrial situations.

All in all, it is an affordable and powerful open-frame industrial generator and is probably the best option in its class.
