Description

This Powerhorse Portable Generator with Electric Start combines 9,000 Watts of clean electricity, electric start convenience and a full bank of outlets in one rugged, portable package. 100% copper-wound head and low harmonic distortion (less than 5%) provide safe operation of sensitive electronics.

Zoom on the Powerhorse 9000ES

In a nutshell, the Powerhorse 9000ES is a portable generator mostly geared towards food van owners who know that just a short power outage could lose them hundreds of dollars.

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Powerhorse 9000ES in use

The Powerhorse 9000ES

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.

At a noise rating of 75 dBA (just slightly more noisy than a shower), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use 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).

The 9000ES generates a clean sine wave: providing <5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 10 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle allowing you to easily charge your batteries.

This Powerhorse generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the 9000ES 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

With its dimensions of L29.3 x W26.6 x H26.4 in, the conventional, open frame design of the Powerhorse 9000ES offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 206 pounds. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Powerhorse 9000ES

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, when the oil level is too low, you will be informed by the featured light indicator.

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.

Accessory-wise, along with the previously mentioned features, the Powerhorse 9000ES is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

Emissions

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, making it usable 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).

  • As its weight is 206 pounds, the Powerhorse 9000ES falls in the expected weight range of the devices in the 6500-7500 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Sportsman GEN85KIDF, with a dry weight of only 133 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 75 dBA. If noise emissions are one of your priorities, you may be interested in the Powerhorse 7500i, one of the least noisy generators similarly powerful as this one, rated for 55 dBA.
  • The 9000ES, offering a run time of around 9.6 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Generac XC6500, which is able to run for around 14 hours.
  • 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 reaches an estimated fuel consumption of 0.69 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

Price comparison

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.
