Description

This versatile model operates at a quiet 55dB, making it ideal for use at home or on the job. Dual 120/240 voltage expands usage options, plus the parallel-ready design (cables not included) allows connecting to another 120/240V inverter generator for more power.

Zoom on the Powerhorse 7500i

In a nutshell, the Powerhorse 7500i is a quiet and powerful portable inverter generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating buffs looking to enhance their experience
  • 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, along with its emission compliance information.

Power & Run Time

The Powerhorse 7500i in use

The Powerhorse 7500i

The Powerhorse 7500i's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 6500W and a peak wattage of 7500W. Moreover, since it is parallel capable (parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.

The inverter generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 55 dBA (just slightly more noisy than a conversation at home).

The fuel capacity of 6.6 gallons allows the 7500i to operate for up to 16 hours with a full tank (fuel consumption around 0.41 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the 7500i produces a clean sine wave, with a <1.5% Total Harmonic Disruption (THD).

Outlets

The control panel features the following 7 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
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 you may charge electronics, for example mobile phones or tablets, conveniently.

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, since the 7500i 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

Since the Powerhorse 7500i is an inverter generator, its closed design (L37.4 x W30.1 x H30.4 in) has an esthetical advantage over conventional, open frame devices. This modern design aims to provide an ideal power solution to recreational users.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 287 pounds. Still, once it is on the ground, its set of wheels 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 7500i

The 7500i's control panel

Monitoring of the 7500i's status and activity is made possible by a digital data center, which provides information on the fuel level, lifetime run hours, voltage, power output and remaining run time and is one of the features of its control panel.

In addition to this info, some light indicators allow you to instantly see if the generator is ready, its oil levels are insufficient and the generator is overloaded.

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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Powerhorse 7500i also comes with some accessories: tool kit and funnel are included.

Emissions

The Powerhorse 7500i is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

Product Videos

The Powerhorse 7500i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 7500i compare to generators of similar power (between 6000 and 7000 W).

  • With its weight of 287 lbs, the Powerhorse 7500i is one of the heavier generators in the 6000-7000 rated wattage category. In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
  • With a lowest possible noise of 55 dBA, this inverter generator places itself amongst the most quiet of the products delivering similar power.
  • The 7500i provides a higher run time than similarly powerful devices, reaching up to 16 hours at 25% load. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen6000, boasting with up to 18 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this inverter generator uses an estimated 0.41 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV8000. With a fuel consumption of as little as 0.35 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 6000-7000W generators, the Powerhorse 7500i is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

    Super quiet beyond what you expect, very good fit and finish, well made. Powers our 1100 sq ft home and 3 ton air conditioning easily.
    Simply attach the wheels and front legs, conveniently add oil, attach the included battery, gas her up – starts immediately and you are ready to go.
    Glad we found this generator.

    + PROS:
    • Quiet, well made, powerful, lots of features, simple set up.
    - CONS:
    • None.

    I purchased the 7500i last year prior to a hurricane and thankfully didn’t have to use it. This year Hurricane Ida came through and the unit performed perfectly.
    It was very quiet, fuel consumption was very low compared to my much older generator. It powered refrigeration, lights etc and never strained.

    + PROS:
    • Ver quiet and efficient compared to older models. Worth the extra money.
    - CONS:
    • Was more expensive.
