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 sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • RV travellers who wish to upgrade their experience to another level

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 GP3300i in use

The Generac GP3300i

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 2500W as well as a peak wattage of 3300W. In addition, the device is parallel capable (parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

Its starting mechanism is based on 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 Disruption (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

In addition, it provides 2 DC outlets: there's two 5V USB ports with which charging of electronics like mobile phones and tablets is made convenient.

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

Since the Generac GP3300i is an inverter generator, its closed design (L22.2 x W13.3 x H18.4 in) has an esthetical advantage over conventional, open frame devices. This type of design is the most modern and convenient way to recreationally generate power.

The GP3300i's dry weight of 59.5 lbs lets you use its power anywhere needed. Additionally, a conveniently placed handle (molded in the case) is a great enhancement to the grip, which tremendously helps when moving the GP3300i across any distance.

Features

Panel of the Generac GP3300i

The GP3300i's control panel

The device’s light indicators will display if the generator is overloaded, the generator is ready and its oil levels are insufficient.

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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Generac GP3300i also comes with some accessories: funnel, tool kit and oil are included.

Emissions

The Generac GP3300i is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

Product Videos

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 weight is your top priority, one of the champions in this power category is the Ford FG2300iS, weighing just 46.3 pounds.
  • Autonomy-wise, with up to 7 hours on a full tank at a 25% load, the GP3300i is on the low end when compared to other inverter generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EU3000iS, reaching up to 20 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen2500, which has a fuel consumption of only 0.1 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 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.
