Zoom on the Firman P03602

In a nutshell, the Firman P03602 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 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 P03602 in use

The Firman P03602

The Firman P03602's engine, 208 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3650W and reaches a peak wattage of 4550W.

Enjoying a noise rating of 68 dBA (less noisy than background music), this generator gets running thanks to a conventional pull-start mechanism.

Thanks to a fuel capacity of 5 gallons, the P03602 can operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

The P03602 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

Outlets

The control panel includes the following 4 AC outlets:

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

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

Portability

The Firman P03602 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 generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 108.5 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Firman P03602

The P03602's control panel

The P03602 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 its oil levels are insufficient.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman P03602, the following accessories are also included: oil, funnel and tool kit.

Emissions

The Firman P03602 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.

The Firman P03602 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P03602 compare to generators of similar power (between 3500 and 4500 W).

  • Having a dry weight of 108.5 lbs, the Firman P03602 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 68 dBA. 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 P03602 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides 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. This generator has an estimated fuel consumption of roughly 0.36 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.
According to our stats, the following comparison is pretty popular: Firman P03602 vs Firman P03501.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman P03602 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.
