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 short, the Powerhorse 7500i is a quiet and powerful portable inverter generator adequately designed for:
- Food truck owners who do not wish to see their business interrupted under any circumstances
- 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 ensure that a power failure will not prevent them from working
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The Powerhorse 7500i
Powerhorse 7500i is equipped with a 420 cc Loncin OHV 4-stroke engine, running on gasoline and providing 120/240V, boasting a running wattage of 6,500W alongside a starting wattage of 7,500W. 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.
Enjoying a noise rating of 55 dBA (just slightly more noisy than a refrigerator), this inverter generator offers the versatility of starting with either a simple traditional pull-start mechanism or a convenient and efficient electric starter (battery included).
The 7500i boasts a fuel tank capable of holding 6.6 gallons, allowing it to run continuously for up to 16 hours (with fuel usage averaging around 0.41 gallons per hour).
The 7500i produces a clean sine wave: thanks to a <1.5% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.
Outlets
The control panel features 7 AC outlets as follows:
Furthermore, it showcases 2 DC outlets: there's two 5V USB ports enabling convenient charging of devices like mobile phones and tablets.
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, with its twist-lock L14-30R receptacle, the 7500i is designed to be transfer switch ready, allowing easy connection to your breaker box for powering your home during a blackout.
Portability
As an inverter generator, the Powerhorse 7500i showcases a closed design (L37.4 x W30.1 x H30.4 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. This type of design is the most modern and convenient way to recreationally generate power.
With a weight of 287 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. 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
The 7500i's control panel
Embedded in the control panel of the 7500i, a digital data center serves as a vital feature, offering comprehensive information on the fuel level, voltage, lifetime run hours, remaining run time and power output to aid in monitoring activity and status.
In addition to this info, the light indicators show you if the oil level is too low, the generator is overloaded and the generator is ready.
In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.
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.
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 inverter generators of similar power (between 6000 and 7000 W).
- Tipping the scales at 287 lbs, the Powerhorse 7500i qualifies as one of the heaviest options among inverter generators rated between 6000 and 7000 watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGDA70BiSCO, with a dry weight of just 118 pounds.
- Rated at a lowest possible noise level of 55 dBA, this inverter generator positions itself amongst the most quiet of the products of similar type and power.
- At 25% load, the 7500i boasts a higher run time than most similarly powerful inverters, reaching up to 16 hours. If prolonged run time is essential to your needs, you could consider the Westinghouse iGen8200TFc, which offers one of the highest autonomy among devices with similar power output, lasting up to 17 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. When it comes to fuel efficiency among generators with similar wattage, this inverter generator lags behind, with a consumption rate of 0.41 GPH at a 25% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse iGen8200TFc, which has an impressively low fuel consumption of 0.23 GPH.
The bottom line
- GFCI Outlets
- 4 different AC outlet types
- Electric start
- Parallel capable
- Inverter
- Quiet for its power (55 dBA)
- High run time
- No remote start
- On the heavy side (287 lbs)
- Low fuel efficiency

User Reviews
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.
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.
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.
