Zoom on the Firman P03501

In a nutshell, the Firman P03501 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
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman P03501 in use

The Firman P03501

The Firman P03501's core is the 208 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3550W and a peak wattage of 4450W.

At a noise rating of 67 dBA (less noisy than an office), the generator is started via a conventional pull-start mechanism.

With a fuel capacity of 5 gallons, the P03501 may run for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

The powering of sensitive electronic devices with the P03501 is not recommended due to its relatively high THD (<25%).

Outlets

The control panel features the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.

Portability

The Firman P03501 has the following dimensions: L24.8 x W21.7 x H21.7 in. In combination with its conventional, open frame design, they provide support and allow 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 108.5 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 Firman P03501

The P03501's control panel

The P03501 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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 the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P03501's package also includes these accessories: oil, funnel, tool kit and cover.

Emissions

The Firman P03501 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.

The Firman P03501 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P03501 compare to generators of similar power (between 3500 and 4500 W).

  • At a weight of 108.5 pounds, the Firman P03501 places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • Since the generator's noise is rated at 67 dBA, it has the roughly average expected noise for a device of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cummins Onan P4500i, whose lowest noise levels reach just 52 dBA.
  • Thanks to an impressive running time of around 14 hours at 50% load, the P03501 benefits from a higher run time than many generators of a similar output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Firman P03501 vs Firman P03602.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman P03501 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
