Zoom on the Firman P03501

In a nutshell, the Firman P03501 is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including 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.

With a noise rating of 68 dBA (less noisy than an office), the generator features a conventional pull-start mechanism.

The fuel capacity of 5 gallons allows the P03501 to operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

The quite high THD (<25%) of the P03501 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel provides the upcoming 4 AC outlets:

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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.

Portability

The Firman P03501 has a conventional, open frame design, of the following dimensions: L24.8 x W21.7 x H21.3 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

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 108.5 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

Panel of the Firman P03501

The P03501's control panel

The P03501's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, a light indicator serves to show you when its oil levels are insufficient.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P03501 also is packed along with the following accessories: tool kit, cover, oil and funnel.

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 and therefore, can be used 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).

  • As its weight is 108.5 pounds, the Firman P03501 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • Because this generator emits noise as low as 68 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • The P03501 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for 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 fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
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 average side of the price range.

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