Zoom on the Powerhorse 9000ES

In a nutshell, the Powerhorse 9000ES is a portable generator mostly geared towards:

  • Food truck owners who do not wish to see their business interrupted under any circumstances
  • Homeowners in need of an emergency backup power for their essentials

In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.

Power & Run Time

The Powerhorse 9000ES in use

The Powerhorse 9000ES

The Powerhorse 9000ES's engine, 420 cc (12.5 hp) OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 7,250W and reaches a peak wattage of 9,000W.

With a noise rating of 75 dBA (just slightly more noisy than a vacuum cleaner), the generator features a traditional recoil pull-start mechanism, but also a user-friendly and hassle-free electric starter (battery not included).

The fuel capacity of 6.6 gallons allows the 9000ES to operate for around 9.6 hours at 50% load with a full tank (fuel consumption around 0.69 GPH).

With a <5% Total Harmonic Distortion (THD), the 9000ES delivers a clean sine wave—essential for safeguarding your delicate electronics when plugged into its AC outlets.

Outlets

The control panel provides the upcoming 10 AC outlets:

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

Furthermore, it showcases 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle enabling simple battery charging for added ease.

Despite not meeting the 'RV Ready' criteria, this Powerhorse generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor. Besides, thanks to its twist-lock L14-30R receptacle, the 9000ES is transfer switch ready, facilitating easy hookup to your breaker box to provide backup power for your home during blackouts.

Portability

At L29.3 x W26.6 x H26.4 in, the Powerhorse 9000ES boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 206 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the limited maneuverability is remedied with its wheel kit and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.

Features

The 9000ES's control panel

The 9000ES and its control panel include a handy voltmeter that allows you to easily monitor power output anytime. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.

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.

As for its accessories, apart from the previously mentioned features, the Powerhorse 9000ES also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

The Powerhorse 9000ES versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 9000ES compare to generators of similar power (between 6500 and 7500 W).

  • With a dry weight of 206 lbs, the Powerhorse 9000ES sits comfortably within the expected weight range for devices generating 6500 to 7500 rated watts. In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
  • As this generator can emit noise as low as 75 dBA, it finds itself in the average expected noise for this kind of power. If you'd like a less noisy alternative, the Powerhorse 7500i is a strong contender. It boasts a noise rating of 55 dBA, placing it among the quietest generators in its power category.
  • At a 50% load, the 9000ES's around 9.6 hours of runtime on a full tank fall within the average autonomy range for similarly powerful generators. If prolonged run time is essential to your needs, you could consider the Predator 9000, which offers one of the highest autonomy among devices with similar power output, lasting around 13 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. As this generator uses an estimated 0.69 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to further improve in the area of fuel efficiency, the Energizer eZV7500, which boasts with a gas consumption of only 0.45 GPH, may be the right generator for you.

What does the throttle control switch do? Should I have it on? Couldn’t find information in manual. I have the powerhorse 9000E (Asked October 30, 2020)

This feature senses the load on the generator. With no load on the generator the engine speed drops to idle, which saves fuel and lengthens engine life. When a load is applied, the engine speed returns to maximum RPMs. Turning the switch off disables the sensing device and the generator will run at maximum RPM whether or not a load is applied.

Will it run a hot water heater (Asked November 14, 2020)

Most likely, yes. But it's always better to check your appliance's data plate to know its actual power needs.

How do I get a replacement throttle control switch for 9000? (Asked March 17, 2021)

Replacement parts can be ordered from Northern Tool.

Is this an inverter generator? (Asked March 18, 2022)

The unit is not an inverter generator, but it has a low THD.
