Zoom on the Powerhorse 9000ES
In summary, the Powerhorse 9000ES is a portable generator especially useful for:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
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 Powerhorse 9000ES is powered by a 420 cc (12.5 hp) OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 7250W as well as a peak wattage of 9000W.
With a noise rating of 75 dBA (just slightly more noisy than a shower), the generator features a conventional pull-start mechanism, but also a simple and elegant electric starter (battery not included).
The 9000ES can operate for around 9.6 hours at 50% load with a full tank (fuel consumption around 0.69 GPH), due to its fuel capacity of 6.6 gallons.
Sensitive electronics can be safely plugged in the AC outlets, as the 9000ES produces a clean sine wave, with a <5% Total Harmonic Disruption (THD).
The control panel provides the upcoming 10 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which charging your batteries is made easy.
Even though this Powerhorse generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as the 9000ES holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.
The Powerhorse 9000ES has a conventional, open frame design, of the following dimensions: L29.3 x W26.6 x H26.4 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 206 lbs make it incredibly difficult to manually lift and transport. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
The control panel of the 9000ES includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.
In addition to this info, a light indicator shows you if the oil level is too low.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, which makes it suitable for use in forested areas.
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).
- Having a dry weight of 206 lbs, the Powerhorse 9000ES belongs in the expected weight range for generators which produce 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.
- This generator has a somewhat average expected noise for its power range, rated at 75 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Powerhorse 7500i with only 55 dBA.
- Autonomy-wise, with around 9.6 hours on a full tank at a 50% load, the 9000ES is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Generac XC6500, as it provides around 14 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Standing at an estimated 0.69 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.
As you can see from this interactive chart, when compared to other 6500-7500W generators, the Powerhorse 9000ES is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.

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.
