Description

Zoom on the Powerhorse 11050

In summary, the Powerhorse 11050 is a powerful portable generator especially useful for:

  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 11050's design includes a gasoline-fueled 457 cc OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 8400W and also a peak wattage of 11050W.

The generator is rated for a noise of 78 dBA (less noisy than a dishwasher). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery not included).

With a fuel capacity of 6.6 gallons, the 11050 may run for around 8.5 hours at 50% load with a full tank (fuel consumption around 0.78 GPH).

Outlets

The control panel includes the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

Since the 11050 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The Powerhorse 11050 has a conventional, open frame design, of the following dimensions: L30 x W26.3 x H26.1 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.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 260 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

The 11050's control panel

To help you monitor the 11050's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, a light indicator serves to show you when its oil levels are insufficient.

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

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Powerhorse 11050 also comes with several accessories, including: tool kit and funnel.

Emissions

The Powerhorse 11050 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 11050 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 11050 compare to generators of similar power (between 7500 and 8500 W).

  • At a dry weight of 260 pounds, the Powerhorse 11050 is one of the heavier devices which can produce between 7500 and 8500 running watts. Regarding dry weight, one of the champions in the same power range is the Dewalt DXGNR8000, with a dry weight of only 183 lbs.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 78 dBA can be considered somewhat noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Predator 9500 with only 67 dBA.
  • Regarding its autonomy, the autonomy of the 11050, reaching around 8.5 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 100416, as it provides around 12.5 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 has an estimated fuel consumption of roughly 0.78 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse WPro8500, with a fuel consumption of 0.55 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 7500-8500W generators, the Powerhorse 11050 is on the average side of the price range.

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