Description

An affordable solution for recreational applications, the GP2500i is the perfect size for tailgating,camping and power on the go. (source: Generac (opens in a new tab))

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 buffs looking to enhance their experience
  • 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 in use

The Generac GP2500i

The Generac GP2500i's engine, 98 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2,200W and reaches a peak wattage of 2,500W. 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 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.

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).

Outlets

The control panel includes the following 2 AC outlets:

Duplex 120V 20A (5-20R)

It also sports 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 with which you may charge your batteries with ease.

Portability

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. The generator has a contemporary design, convenient for recreationally generating power.

Labeled a lightweight portable generator, the GP2500i weighs just 48 lbs. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. Its handle (molded in the case) allows you to carry it easily, further enhancing its convenience.

Features

Panel of the Generac GP2500i

The GP2500i's control panel

The device’s light indicators will display if the generator is ready, the oil level is too low and the generator is on overload.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Generac GP2500i also is packed along with the following accessories: funnel, tool kit, oil and battery charging cables.

Emissions

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, so it is adequate for use in forested areas.

Product Video

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.

Price comparison

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.

    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.

    + PROS:
    • Light weight portable not to heavy
    - CONS:
    • I didn’t have any

    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
