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 outdoor fairs, festivals or events
  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials

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 engine, 208 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3250W and reaches a peak wattage of 3750W.

The generator features a conventional pull-start mechanism.

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

Since the GP3250 has a somewhat high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 3 AC outlets:

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

Portability

The Generac GP3250 has a conventional, open frame design, of the following dimensions: L22.75 x W22 x H21 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 110 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). 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

The GP3250's control panel

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 overload protection (circuit breaker) and an automatic low oil shut-off.

As for its accessories, apart from the previously mentioned features, the Generac GP3250 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

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, which makes it suitable 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).

  • Considering its dry weight of 110 pounds, the Generac GP3250 is one of the heavier generators producing between 2500 and 3500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Generac GP3300i, with a dry weight of just 59.5 pounds.
  • Regarding its autonomy, the autonomy of the GP3250, reaching around 9.7 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. 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.
  • 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 generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. 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 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.
