Zoom on the Generac GP2500i
In summary, the Generac GP2500i is a compact and lightweight portable inverter generator especially useful for:
- Camping and tailgating hobbyists looking for a portable power source
- DIYers who wish to improve their efficiency with tools
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Generac GP2500i houses a 98 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 2200W along with a peak wattage of 2500W. Additionally, as the generator is parallel capable (7118 parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
This inverter generator features a simple traditional pull-start mechanism.
The GP2500i can operate for up to 8 hours with a full tank (fuel consumption around 0.13 GPH), due to its fuel capacity of 1 gallon.
As the GP2500i produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
The control panel features the upcoming 2 AC outlets:
In addition, it provides 3 DC outlets: there's two 5V USB ports allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 8A receptacle allowing you to easily charge your batteries.
Thanks to its closed inverter generator design (L19.7 x W11.4 x H17.9 in), the Generac GP2500i, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.
The GP2500i is a lightweight, portable generator, as it only weighs 48 lbs. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. This convenience is further enhanced thanks to its handle (molded in the case) that allows you to carry it with ease.
The light indicators show you if the generator is overloaded, the oil level is too low and the generator is ready.
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.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Generac GP2500i also comes with some accessories: battery charging cables, oil, funnel and tool kit are included.
The Generac GP2500i is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used in forested areas.
The Generac GP2500i versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP2500i compare to inverter generators of similar power (between 1500 and 2500 W).
- At a weight of 48 pounds, the Generac GP2500i 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.
- The GP2500i's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 8 hours at 25% load on a full tank. 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.
- 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 is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.13 GPH at a 25% load. 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.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 1500-2500W inverter generators, the Generac GP2500i is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
The bottom line
