Zoom on the Generac GP2500i
In a nutshell, the Generac GP2500i is a compact and lightweight portable inverter generator mostly geared towards:
- Camping and tailgating hobbyists looking for a portable power source
- Handcrafting enthusiasts who wish to work on-the-go
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
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.
With a fuel capacity of 1 gallon, the GP2500i may run 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 Distortion (THD).
The control panel provides the upcoming 2 AC outlets:
Furthermore, it has 3 DC outlets: there's two 5V USB ports (1 x USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle with which you may charge your batteries with ease.
Since the Generac GP2500i is an inverter generator, its closed design (L19.7 x W11.4 x H17.9 in) has an esthetical advantage over conventional, open frame devices. This type of design is the most modern and convenient way to recreationally generate 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. It can also be carried without effort with a featured handle (molded in the case), further improving its convenience.
When the oil level is too low, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).
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.
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: tool kit, funnel, oil and battery charging cables are included.
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 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 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.
