Zoom on the Generac GP2500i
In a nutshell, the Generac GP2500i is a compact and lightweight portable inverter generator mostly geared towards:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- Handcrafting enthusiasts who wish to work on-the-go
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with 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 2,200W along with a peak wattage of 2,500W. In addition, as it is parallel capable (7118 parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.
This inverter generator gets running thanks to 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.
Delicate electronics can be plugged in an AC outlets safely, as the GP2500i generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).
The control panel provides the upcoming 2 AC outlets:
It also sports 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 with which you may charge your batteries with ease.
As the Generac GP2500i is an inverter generator, its encased design (L19.7 x W11.4 x H17.9 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.
Labeled a lightweight portable generator, the GP2500i weighs just 48 lbs. The device can be easily moved by just one person and thus, its power may be enjoyed on-the-go. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
The light indicators show you if the generator is on overload, its oil levels are insufficient and the generator is ready.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Generac GP2500i's package also includes these accessories: tool kit, battery charging cables, funnel and oil.
The Generac GP2500i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor, so it is adequate for use 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
- In the expected price range
- Several accessories included
- Parallel capable
- Decent weight (48 lbs)
- No data center
- No electric start
- Relatively low run time

It works well but support from Generac for the small portables is pathetic. I won’t buy another one.
I lost power due to a storm bought this 2500 to get me through great little generator. I ran my refrigerator my furnace, my fish tank and a couple of lights ran 4 1/2 hours until the power came back on and only used a half a tank of gas. For the money great product.
Drinks gas at anything past idle which is any load over 5 amps
EXTREMELY NOISY!! Even with light load. I placed it 30 ft from my camper with the exhaust pointed away and it kept me up all night. If I could get all my money back on this, I would do it and buy a better one that wasn’t so noisy. Had one years ago that was so quiet I couldn’t hear it at all from 30 ft
