Description
Zoom on the Generac GP3300i
In a nutshell, the Generac GP3300i is a compact and lightweight portable inverter generator mostly geared towards:
- Camping and tailgating hobbyists looking for a portable power source
- Amateur DIY lovers
- 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 following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
Generac GP3300i runs on gasoline, powered by a 149 cc Generac OHV 4-stroke engine, delivering 120V, boasting a running wattage of 2,500W alongside a starting wattage of 3,300W. Moreover, the parallel capability (parallel kit (opens in a new tab) not included) allows for doubling of power output when paired with another similar or compatible unit, providing increased energy capacity and reliability for diverse needs.
Its starting mechanism relies on a simple traditional pull-start mechanism. It features Generac's PowerDial™, an easy-to-use dial with three operation settings.
The GP3300i can operate for up to 7 hours with a full tank (fuel consumption around 0.15 GPH), due to its fuel capacity of 1.06 gallon.
The GP3300i generates a clean sine wave with <3% Total Harmonic Distortion (THD), ensuring minimal electrical noise and fluctuations. This feature makes it ideal for powering sensitive electronics, providing stable and reliable AC power through the outlets.
Outlets
The control panel is equipped with the following 3 AC outlets:
Moreover, it comes equipped with 2 DC outlets: there's two 5V USB ports (USB-A) ideal for charging various electronic devices such as smartphones and tablets.
Even though this Generac generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor.
Portability
Thanks to its closed inverter generator design (L22.2 x W13.3 x H18.4 in), the Generac GP3300i not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. This type of design is the most modern and convenient way to recreationally generate power.
At 59.5 lbs, the GP3300i is easily managed, ensuring it can be brought along wherever you need power. Furthermore, the GP3300i's easy transport from A to B is facilitated by its convenient handle (molded in the case), which enhances grip.
Features
Light indicators on the device will notify you if the generator is ready, the generator is on overload and its oil levels are insufficient.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
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.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Generac GP3300i ships with supplementary accessories: 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).
- In terms of its weight, the Generac GP3300i weighs merely 59.5 pounds, earning it a spot among the lighter inverter generators within the 2000 to 3000 rated wattage category. Weight-conscious users may find the WEN 56280iX appealing, as it is one of the top contenders in this power range, weighing just 41.9 pounds.
- In terms of autonomy, the GP3300i offers up to 7 hours at a 25% load, placing it at the lower range within its type and power range. If you wish to prioritize autonomy, the Honda EU3000iS shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling 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. At a 25% load, the inverter generator consumes an estimated 0.15 gallons of gasoline per hour, falling within the average consumption range of units with similar output. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen2800c, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.

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.
