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 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 is powered by a 98 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2200W as well as 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 is started via 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 following 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.
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. This type of design is the most modern and convenient way to recreationally generate power.
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.
When its oil levels are insufficient, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.
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.
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: funnel, oil, battery charging cables and tool kit.
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).
- As for its weight, the Generac GP2500i weighs only 48 pounds, making it one of the lighter generators in the 1500-2500 rated wattage category. If weight matters to you, one of the champions in this power range is the Champion 200949 with only 38.6 pounds.
- Regarding its autonomy, the autonomy of the GP2500i, reaching up to 8 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen2000, as it provides up to 26 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. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.13 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the Predator 2000 is a device you should look out for.
Here's a list of the most popular specific comparisons:
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)
- No data center
