Description
Zoom on the Powerhorse 2500i
To sum up, the Powerhorse 2500i is a compact and lightweight portable inverter generator tailored for:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- DIYers who wish to improve their efficiency with tools
- RV travellers who wish to upgrade their experience to another level
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 2500i utilizes a 80 cc (3 hp) OHV 4-stroke engine to deliver 120V, offering a running wattage of 1,800W and a starting wattage of 2,500W. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.
Operating with a noise level of 62 dBA (just slightly more noisy than a normal conversation), the inverter generator starts up via a standard recoil pull-rope starting mechanism.
With a fuel capacity of 1.2 gallon, the 2500i can run for up to 10.5 hours when the tank is full (fuel consumption is approximately 0.11 gallons per hour).
As the 2500i produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel features the following 3 AC outlets:
Even if this Powerhorse generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.
Portability
As the Powerhorse 2500i is an inverter generator, its encased design (L20.4 x W12.5 x H18.3 in) offers more aesthetics than a conventional, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.
At a mere 48.3 lbs, the 2500i is a standout option for those in need of a lightweight and portable power solution. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
Features
When the generator is overloaded, the generator is ready and the oil level is too low, you will be informed by the featured light indicators.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Powerhorse 2500i also comes with several accessories, including: tool kit and funnel.

The Powerhorse 2500i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Powerhorse 2500i compare to inverter generators of similar power (between 1500 and 2500 W).
- At a weight of 48.3 pounds, the Powerhorse 2500i places in the expected weight range of the inverter generators in the 1500-2500 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM2000i, standing at just 34.2 lbs.
- This inverter generator, with its lowest possible noise rated at 62 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 48 dBA.
- Given that the 2500i reaches an autonomy of up to 10.5 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful inverter generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP2300iH, boasting with up to 13 hours.
- Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. With a fuel usage of about 0.11 GPH at a 25% load, this inverter generator falls within the typical gasoline consumption range observed in comparably powerful products. If fuel consumption is your top priority, we suggest to check out the DuroMax XP2300iH, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 1500-2500W inverter generators, the Powerhorse 2500i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
