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 summary, the Powerhorse 7500i is a quiet portable inverter generator especially useful for:

  • 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
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 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. In addition, the device is parallel capable (parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

Enjoying a noise rating of 55 dBA (just slightly more noisy than a conversation at home), this inverter generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

With a fuel capacity of 6.6 gallons, the 7500i may run for up to 16 hours with a full tank (fuel consumption around 0.41 GPH).

The 7500i generates a clean sine wave: providing <1.5% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

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

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

This Powerhorse generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, because the 7500i is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

Thanks to its closed inverter generator design (L37.4 x W30.1 x H30.4 in), the Powerhorse 7500i, is more esthetical than a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 287 lbs. 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.

Features

Panel of the Powerhorse 7500i

The 7500i's control panel

To help you monitor the 7500i's status and activity, its control panel is equipped with a digital data center, giving you information on the fuel level, lifetime run hours, remaining run time, power output and voltage.

In addition to this info, several light indicators serve to show you when the generator is ready, the oil level is too low and the generator is overloaded.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Powerhorse 7500i, the following accessories are also included: tool kit and funnel.

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, so it is adequate for use in forested areas.

Product Video

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).

  • At a dry weight of 287 pounds, the Powerhorse 7500i is one of the heavier devices which can produce between 6000 and 7000 running watts. If you are concerned by weight, one of the champions in the above mentioned power range is the Sportsman GEN85KIDF, with a dry weight of just 133 pounds.
  • With a lowest possible noise of 55 dBA, this inverter generator places itself amongst the most quiet of the products delivering similar power.
  • Offering up to 16 hours of running time on a full tank at 25% load, the 7500i is within the average autonomy range of similarly powerful generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WH7500v, as it provides up to 18 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.41 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV7500, with a fuel consumption of 0.35 GPH could be in your good books.

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.

    I have a 7500i when I bought it it ran perfect when it came time to be serviced i too it back to northern boy was that a mistake I got it back it wouldn’t run right it keeps braking fuzes and loosing power for some reason it won’t hold a load it worked fine before I got it serviced. I like the 7500i I would get another one.

    + PROS:
