Zoom on the Generac GP3250

In summary, the Generac GP3250 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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 houses a 208 cc Generac OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3,250W along with a peak wattage of 3,750W.

This generator is started via 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.

The powering of sensitive electronic devices with the GP3250 is not recommended due to its high THD (<20%).

Outlets

The control panel features the upcoming 3 AC outlets:

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

Portability

With its dimensions of L22.75 x W22 x H21 in, the conventional, open frame design of the Generac GP3250 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 110 pounds. Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the Generac GP3250

The GP3250's control panel

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

Along with the aforementioned features, from an accessory standpoint, the Generac GP3250's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

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 and therefore, can be used 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).

  • Since the generator weighs in at a dry weight of 110 lbs, the Generac GP3250 belongs in the expected weight range for devices which can produce between 2500 and 3500 rated watts. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
  • The GP3250, offering a run time of around 9.7 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. 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.
  • 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.36 GPH. If fuel consumption is your top priority, we suggest to check out the Pulsar PGD40iSCO, which has a fuel consumption of only 0.22 GPH and thus, is one of the most efficient devices in our database.
According to our stats, the following comparison is pretty popular: Generac GP3250 vs Generac GP3300.

The bottom line

STRENGTHS:

The Generac GP3250 doesn't have any specs that exceed those of other generators of its class.

AVERAGE SPECS:
  • Decent weight (110 lbs)
  • Decent run time
WEAKNESSES:
  • No data center
  • No electric start
  • Not CARB-compliant
  • Low fuel efficiency
