Zoom on the Generac GP2500i
In summary, the Generac GP2500i is a compact and lightweight portable inverter generator especially useful for:
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
- Amateur DIY lovers
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's design includes a gasoline-fueled 98 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 2200W and also a peak wattage of 2500W. Moreover, since it is parallel capable (7118 parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.
This inverter generator features a conventional pull-start mechanism.
The fuel capacity of 1 gallon allows the GP2500i to operate for up to 8 hours with a full tank (fuel consumption around 0.13 GPH).
Sensitive electronics can be safely plugged in the AC outlets, as the GP2500i produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).
The control panel features the upcoming 2 AC outlets:
Additionally, it features 3 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle allowing you to easily charge your batteries.
The Generac GP2500i is an inverter generator and has an encased design of the following dimensions: L19.7 x W11.4 x H17.9 in. Thus, it is more aesthetical than conventional, open frame products. The design follows the contemporary trends and is perfect for recreationally generating power.
Labeled a lightweight portable generator, the GP2500i weighs just 48 lbs. A single person should not have any problems moving it around and thus, enjoy power availability on-the-go. Further convenience is provided by its handle (molded in the case), as it allows you to carry it effortlessly.
The light indicators show you if the generator is ready, the generator is on overload and the oil level is too low.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac GP2500i, the following accessories are also included: battery charging cables, tool kit, oil and funnel.
The Generac GP2500i is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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 generators of similar power (between 1500 and 2500 W).
- Weight-wise, the Generac GP2500i has only 48 lbs, which renders it one of the lighter generators which produce 1500 to 2500 rated watts. If weight matters to you, one of the champions in this power range is the Champion 200949 with only 38.6 pounds.
- As for its autonomy, the GP2500i, with an autonomy of up to 8 hours at a 25% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen2000, which is able to run for up to 26 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 reaches an estimated fuel consumption of 0.13 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Predator 2000. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 1500-2500W 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
- Lightweight (48 lbs)
