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
- Amateur DIY lovers
Power & Run Time
The Generac GP2500i's design includes a gasoline-fueled 98 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 2,200W and also 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.
Thanks to a fuel capacity of 1 gallon, the GP2500i can operate for up to 8 hours with a full tank (fuel consumption around 0.13 GPH).
The GP2500i generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel features the upcoming 2 AC outlets:
Additionally, it features 3 DC outlets: there's two 5V USB ports (1 x USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 8A receptacle with which charging your batteries is made easy.
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 type of design is the most modern and convenient way to recreationally generate power.
With a weight of only 48 lbs, the GP2500i may be viewed as a lightweight and portable generator. 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.
Several light indicators serve to show you when the generator is ready, its oil levels are insufficient and the generator is overloaded.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
The GP2500i also benefits from Generac’s COsense® carbon monoxide monitoring. This technology senses and manages CO output and shuts down the unit when necessary, to protect you from CO poisoning.
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: oil, tool kit, battery charging cables and funnel.
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 therefore, can 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).
- Since the generator weighs in at a dry weight of 48 lbs, the Generac GP2500i belongs in the expected weight range for inverters which can produce between 1500 and 2500 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroMax XP2300iH, which is able to run for up to 13 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.13 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the DuroMax XP2300iH, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.
Here's a list of the most popular specific comparisons:
As you can see from these interactive charts, 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
- COsense® technology
- Several accessories included
- Parallel capable
- Decent weight (48 lbs)
- No data center
- Relatively low run time
