Zoom on the Generac GP3300i
In summary, the Generac GP3300i is a compact and lightweight portable inverter generator especially useful for:
- Camping and tailgating buffs looking to enhance their experience
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- RV travellers looking for even more independence
Power & Run Time
The Generac GP3300i is powered by a 149 cc Generac OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2,500W as well as 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 gets running thanks to a simple traditional pull-start mechanism. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.
With a full tank, the GP3300i can operate for up to 7 hours (fuel consumption around 0.15 GPH), thanks to its fuel capacity of 1.06 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the GP3300i generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).
The control panel includes the following 3 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.
While this Generac generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
As the Generac GP3300i is an inverter generator, its encased design (L22.2 x W13.3 x H18.4 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.
As the GP3300i's weight is only 59.5 lbs, it can follow you and your power needs anywhere. Moreover, the convenient handle (molded in the case) greatly enhances the grip, making carrying the GP3300i from A to B always an easy task.
When the generator is on overload, its oil levels are insufficient and the generator is ready, 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 overload protection (circuit breaker) and an automatic low oil shut-off.
The GP3300i 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.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Generac GP3300i, the following accessories are also included: tool kit, oil and funnel.
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, so it is adequate for use 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 far as its dry weight is concerned, the Generac GP3300i weighs just 59.5 pounds and thus, it is one of the lighter 2000 to 3000 rated wattage inverter generators. In terms of weight, one of the champions in their power range is the WEN 56360i, standing at just 46.3 lbs.
- The GP3300i's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 7 hours at 25% load on a full tank. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EU3000iS, as it provides 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. Standing at an estimated 0.15 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen2800, 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 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.
