Zoom on the Generac GP3250

In a nutshell, the Generac GP3250 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 GP3250 in use

The Generac GP3250

The Generac GP3250's design includes a gasoline-fueled 208 cc Generac OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3250W and also a peak wattage of 3750W.

The generator features a simple traditional pull-start mechanism.

The GP3250 can operate for around 9.7 hours at 50% load with a full tank (fuel consumption around 0.36 GPH), due to its fuel capacity of 3.5 gallons.

As the GP3250 has a relatively high THD (<20%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120/240V 20A (L14-20R) receptacle

Portability

The dimensions of the Generac GP3250, which are L22.75 x W22 x H21 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 110 lbs. 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 GP3250

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Besides the features previously mentioned, accessory-wise, the Generac GP3250 comes with the usual documentation and owner's manual (opens in a new tab) needed to get you promptly started.

Emissions

The Generac GP3250 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

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

Product Video

The Generac GP3250 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP3250 compare to generators of similar power (between 2500 and 3500 W).

  • At a dry weight of 110 pounds, the Generac GP3250 is one of the heavier devices which can produce between 2500 and 3500 running watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM3300i, with a dry weight of only 47.4 lbs.
  • The GP3250, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 9.7 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 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. As this generator uses an estimated 0.36 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Generac GP3250 vs Generac GP3300.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Generac GP3250 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
