In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
Power & Run Time
The Powerhorse 7500i
The Powerhorse 7500i's engine, 420 cc Loncin OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6,500W and reaches a peak wattage of 7,500W. Furthermore, its parallel capability (parallel kit (opens in a new tab) not included) allows for increasing of power output when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
At a noise rating of 55 dBA (just slightly more noisy than a quiet suburb), this inverter generator can be started via a manual recoil starter system, or an intuitive and practical electric starter (battery included).
Featuring a 6.6 gallons fuel tank, the 7500i can provide power for up to 16 hours on a full tank (with fuel consumption averaging 0.41 gallons per hour).
Sensitive electronics can be safely plugged in the AC outlets, as the 7500i produces a clean sine wave, with a <1.5% Total Harmonic Distortion (THD).
Outlets
The control panel features the upcoming 7 AC outlets:
Furthermore, it has 2 DC outlets: there's two 5V USB ports perfect for conveniently charging mobile phones, tablets, and other electronic devices.
While this Powerhorse generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, since it boasts a twist-lock L14-30R receptacle, the 7500i 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 its enclosed inverter generator design (L37.4 x W30.1 x H30.4 in), the Powerhorse 7500i offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. This type of design is the most modern and convenient way to recreationally generate power.
Since the generator weighs 287 lbs, it could be potentially be difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, its challenging mobility is solved by its set of wheels and its folding handle, which will ease its displacement, once it is on the floor.
Features
The 7500i's control panel
One of the many 7500i's features is the digital data center, included in its control panel, which conveniently provides information on the remaining run time, power output, fuel level, lifetime run hours and voltage and thus, helps you monitor its activity and status.
In addition to this info, several light indicators serve to show you when the generator is on overload, the oil level is too low 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.
In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Powerhorse 7500i also includes several accessories: tool kit and funnel.

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).
- Weighing 287 lbs, the Powerhorse 7500i is one of the heaviest generators within the 6000-7000 rated wattage bracket. If weight is a key factor for your needs, the Pulsar PGDA70BiSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 118 pounds.
- At just 55 dBA rated noise level, this inverter generator is positioned as one of the quietest choices among devices delivering similar power.
- Since the 7500i boasts with a run time of up to 16 hours at 25% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If runtime is a priority for you, the Westinghouse iGen8200TFc stands out as one of the generators with the longest run time in its power range, providing up to 17 hours of continuous use.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.41 GPH (gallon per hour) at a 25% load. If minimizing fuel usage is one of your key priorities, the Westinghouse iGen8200TFc is one of the most efficient devices with similar power output, with a gasoline consumption of only 0.23 gallons per hour.
The bottom line
- GFCI Outlets
- 4 different AC outlet types
- Electric start
- Parallel capable
- Inverter
- Quiet for its power (55 dBA)
- High run time
- Decent fuel efficiency
- No remote start
- On the heavy side (287 lbs)

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.
