Zoom on the Generac GP3300

In a nutshell, the Generac GP3300 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

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 GP3300 in use

The Generac GP3300

The Generac GP3300 is powered by a 163 cc (208 hp) Generac OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3300W as well as a peak wattage of 3750W.

This generator is started via a simple traditional pull-start mechanism.

The fuel capacity of 3.35 gallons allows the GP3300 to operate for around 10.3 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

The quite high THD (<25%) of the GP3300 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 20A (L14-20R) receptacle

Portability

The design of the Generac GP3300 is a typical, open frame, with the dimensions of L24.2 x W22.5 x H21 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 101.5 pounds. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Generac GP3300

The GP3300's control panel

The control panel of the GP3300 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Generac GP3300's package also includes these accessories: oil and RV adapter.

Emissions

The Generac GP3300 is 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.

Product Video

The Generac GP3300 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP3300 compare to generators of similar power (between 2500 and 3500 W).

  • As its weight is 101.5 pounds, the Generac GP3300 falls in the expected weight range of the devices in the 2500-3500 rated wattage category. If weight matters to you, one of the champions in this power range is the Generac GP3300i with only 59.5 pounds.
  • The GP3300, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 10.3 hours at a 50% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. As this generator uses an estimated 0.33 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.
According to our stats, the following comparison is pretty popular: Generac GP3300 vs Generac GP3250.

    I race motorcycle on the road 200 days a year and pull a 30 foot box trailer and I power it with a GP3300 I’ve had in use for three years. It ran longer than my last Honda the Honda blow up in a year come not get part out on the road. The GP 3300 I can get part at the parts store I had a head gasket blow but I was able to repair it with parts the location Auto Zone in a little town in the middle of no were. It ran a year longer. But this year it was cold as hell and had a hard time starting so knowing better I give it a little shot of starting fuel and it was the real fuel it blow the head off I’m talking the hell off broke the head bolts so I was thinking it would not recover from that but i got all my thing together and I old school serfs the head and cyclder with a flat glass an sand paper knock the glaze off the rings and bore work. The cakes use the old gasket old rings new case hard bolts made a push rod holder pull it one time it started smoke back fire for a min and it’s level out and is still running like a new one all this time not a min trouble out of anything else on it. It’s not smoking at all run a little old every 10 tank of fuel. Runs every day and night for 7 years now so yes it’s a damn good tool. So don’t be scared to go get one u want be disappointed at all
