Description
Zoom on the Generac GP3300i
To sum up, the Generac GP3300i is a compact and lightweight portable inverter generator tailored 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 who wish to upgrade their experience to another level
In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.
Power & Run Time
The Generac GP3300i
Running on gasoline, the Generac GP3300i operates with a 149 cc Generac OHV 4-stroke engine, delivering 120V, with a running wattage of 2,500W and a peak wattage of 3,300W. Additionally, as the generator is parallel capable (parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
This inverter generator gets running thanks to a manual recoil starter system. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.
Featuring a 1.06 gallon fuel tank, the GP3300i can provide power for up to 7 hours on a full tank (with fuel consumption averaging 0.15 gallons per hour).
The GP3300i generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel features the following 3 AC outlets:
Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
This Generac generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.
Portability
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. This type of design is the most modern and convenient way to recreationally generate power.
The 59.5 lbs of the GP3300i's dry weight enables you to use it anywhere you will ever need. Moreover, the convenient handle (molded in the case) greatly enhances the grip, ensuring that carrying the GP3300i from A to B is always an easy task.
Features
The GP3300i's control panel
The device's light indicators will illuminate to indicate if the oil level is too low, the generator is ready and the generator is overloaded.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
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: funnel, tool kit and oil.

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. If you are mindful of weight, the Westinghouse iGen2800 is among the top contenders in this power range, with a dry weight of 46.3 pounds.
- Concerning its runtime, the GP3300i provides up to 7 hours at a 25% load, indicating that it falls on the lower side compared to other generators of its type and power range. If prolonged run time is essential to your needs, you could consider the Honda EU3000iS, which offers one of the highest autonomy among devices with similar power output, lasting 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 has an estimated fuel consumption of roughly 0.15 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen2800, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from these interactive charts, when compared to other 2000-3000W inverter generators, the Generac GP3300i is on the average side of the price range.

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.
