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 GP3300i in use

The Generac GP3300i

The Generac GP3300i's engine, 149 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 2,500W and reaches a peak wattage of 3,300W. Moreover, since it is parallel capable (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. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.

Thanks to a fuel capacity of 1.06 gallon, the GP3300i can operate for up to 7 hours with a full tank (fuel consumption around 0.15 GPH).

As the GP3300i produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle

Additionally, it features 2 DC outlets: there's two 5V USB ports with which you may charge electronics, for example mobile phones or tablets, conveniently.

Even if this Generac generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The Generac GP3300i is an inverter generator and has an encased design of the following dimensions: L22.2 x W13.3 x H18.4 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.

The GP3300i's dry weight of 59.5 lbs lets you use its power anywhere needed. Moreover, shifting it is an easy task, as the GP3300i features a nifty handle (molded in the case), improving your grip greatly.

Features

Panel of the Generac GP3300i

The GP3300i's control panel

The light indicators show you if the generator is on overload, the generator is ready and its oil levels are insufficient.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Generac GP3300i also comes with several accessories, including: funnel, oil and tool kit.

Emissions

The Generac GP3300i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Generac GP3300i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP3300i compare to inverter generators of similar power (between 2000 and 3000 W).

  • As for its weight, the Generac GP3300i weighs only 59.5 pounds, making it one of the lighter inverter generators in the 2000-3000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the WEN 56360i, with a dry weight of only 46.3 lbs.
  • As for its autonomy, the GP3300i, with an autonomy of up to 7 hours at a 25% load, is placed on the low end among the generators of its kind. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EU3000iS, boasting with up to 20 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 can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.15 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Cummins Onan P2500i, with a fuel consumption of 0.1 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 2000-3000W inverter generators, the Generac GP3300i is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.

What is the noise rating of the GP3300i?

Due to the lack of standardization in noise emission measurement, Generac does not provide their units' noise levels.

Can a 3300i be used on a RV that has a surge guard that is hard wired. (Asked June 23, 2021)

The unit has a floating neutral. Your surge guard protection device may detect this as an open ground condition and not allow power to pass through. In that case, you may need to bond the neutral.
