Description

Zoom on the Westinghouse WPro8500

In a nutshell, the Westinghouse WPro8500 is a powerful portable generator mostly geared towards 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 WPro8500 in use

The Westinghouse WPro8500

The Westinghouse WPro8500's engine, 457 cc (13.5 hp) Westinghouse OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 8500W and reaches a peak wattage of 11500W.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the WPro8500 can also be remotely started (key fob included).

The fuel capacity of 6.6 gallons allows the WPro8500 to operate for up to 17.5 hours with a full tank (fuel consumption around 0.38 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the WPro8500 produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).

Outlets

The full GFCI control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets.

This Westinghouse generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as it features a twist-lock L14-30R receptacle, the WPro8500 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.

Portability

The Westinghouse WPro8500 has a conventional, open frame design, of the following dimensions: L27.5 x W27.5 x H25.5 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

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 216 lbs. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

The WPro8500's control panel

The WPro8500's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

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

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Westinghouse WPro8500, the following accessories are also included: tool kit, funnel, battery charger, key fob and oil.

Emissions

The Westinghouse WPro8500 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.

The Westinghouse WPro8500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Westinghouse WPro8500 compare to generators of similar power (between 8000 and 9000 W).

  • Since the generator weighs in at a dry weight of 216 lbs, the Westinghouse WPro8500 belongs in the expected weight range for devices which can produce between 8000 and 9000 rated watts. If weight is your top priority, one of the champions in this power category is the Lifan LF8750iEPL, weighing just 185 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. 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.
  • As the WPro8500 features an autonomy of up to 17.5 hours at 25% load, it has one of the highest run times in comparison to the other generators of its power range.
  • 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, with an estimated fuel consumption of just 0.38 GPH (gallon per hour) at 25% load, is one of the most fuel efficient generators, for the previously mentioned wattage range.
According to our stats, the following comparison is pretty popular: Westinghouse WPro8500 vs Westinghouse WGen9500.

Price comparison

As you can see from this interactive chart, when compared to other 8000-9000W generators, the Westinghouse WPro8500 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

About Westinghouse

The US based Westinghouse Outdoor Power Equipment is a legacy subsidiary of the Westinghouse Electric Corporation, founded in 1886. While the company has been acquired and merged into the American CBS, the Westinghouse name remains as the brand name for many of their electrical solutions, which stretch across the scale from power plants to portable generators – which are the main product of the Outdoor Power Equipment branch of Westinghouse. Lawn equipment, such as trimmers and blowers, is also sold under the Westinghouse brand name. All of their products are designed in the US. However, several sources report that they are in many cases manufactured in China.

Warranty Information

The Westinghouse WPro8500 is covered under a warranty for up to 3 years. This warranty may be limited and may not cover all parts of the generator.

    I use the WPro8500 to power a 10 circuit manual transfer switch for key circuits in our home. Had an issue with the carburetor / solenoid switch after the initial use. Westinghouse sent a replacement carburetor kit that was easy to switch out. I’ve owned two other well known brands and I’m very pleased with this generator.

    + PROS:
    • THD < 5%.
    • A 30 and 50 amp receptacle.
    • Manual, electric and remote start.
    • Output readings.
    • 3 year warranty.
    - CONS:
    • None so far.
