Description
Zoom on the Powerhorse 11050
In a nutshell, the Powerhorse 11050 is a powerful portable generator mostly geared towards:
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to be able to deliver results, even during a power failure
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
Running on gasoline, the Powerhorse 11050 operates with a 457 cc OHV 4-stroke engine, delivering 120/240V, with a running wattage of 8,400W and a peak wattage of 11,050W.
With a noise rating of 78 dBA (less noisy than a vacuum cleaner), the generator features a conventional pull-start mechanism, but also a user-friendly and efficient electric starter (battery not included).
Equipped with a 6.6 gallons fuel tank, the 11050 ensures continuous operation for around 8.5 hours at 50% load with a full tank (fuel usage approximately 0.78 gallons per hour).
Featuring a <5% Total Harmonic Distortion (THD), the 11050 delivers a clean sine wave, guaranteeing the safety of your sensitive electronics plugged into its AC outlets.
Outlets
The control panel features 6 AC outlets as follows:
Additionally, it offers 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.
Since it boasts a twist-lock L14-30R receptacle, the 11050 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
With a size of L30 x W26.3 x H26.1 in, the Powerhorse 11050 features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The design is ideal for rough environments and demanding outdoor use.
While technically classified as 'portable' due to its ability to be moved, the 260 lbs of this generator make manual lifting and transportation incredibly difficult. 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
To help you monitor the 11050's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
In addition to this info, the device's light indicator will illuminate to indicate if the oil level is too low.
Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.
Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.
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.

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 heaviest devices which can produce between 7500 and 8500 running watts. if you wish to prioritize weight, the Genmax GM10500XiT is one of the top contenders in its power category, weighing only 123.5 pounds.
- 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 you'd like a less noisy alternative, the DuroMax XP9500iH is a strong contender. It boasts a noise rating of 61 dBA, placing it among the quietest generators in its power category.
- The 11050's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 8.5 hours at 50% load on a full tank. For those prioritizing autonomy, the Champion 100416 could be considered, as it offers one of the longest run times among generators with similar power output, reaching around 12.5 hours.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. At a 50% load, the generator consumes an estimated 0.78 gallons of gasoline per hour, falling within the average consumption range of units with similar output. If you wish to further improve in the area of fuel efficiency, the Powerhorse s10500id, which boasts with a gas consumption of only 0.59 GPH, may be the right generator for you.

Engine oil capacity is 1.27 qt.
How often should I change the oil? (Asked March 05, 2024)
Oil should be changed after the first month or first 20 hours (whichever comes first), and then every 6 months or 100 hours (whichever comes first). Level should be checked before each use.




User Reviews
I used this generator for 10 hours powering my house. Powered everything but the water heater for 8 hours. Then powered everything including my water heater. I did not power my cook stove at all. Did a fantastic job. Doing the oil change after the 10 hour break in period. And it seem the oil plug may be a little weak so be careful on not over lightning it. So far I’m impressed.
