Power & Run Time

The Firman P03602 in use

The Firman P03602

The Firman P03602 houses a 208 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,650W along with a peak wattage of 4,550W.

Enjoying a noise rating of 67 dBA (less noisy than background music), this generator gets running thanks to a simple traditional 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 high THD (<25%).

Outlets

The control panel features the following 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 design of the Firman P03602 is a typical, open frame, with the dimensions of L24.8 x W21.7 x H21.7 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 108.5 lbs make it incredibly difficult to manually lift and transport. 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

To help you monitor the P03602's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, the device’s light indicator will display if the oil level is too low.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman P03602 also comes with several accessories, including: tool kit, oil and funnel.

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 and therefore, can be used 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).

  • With a dry weight of 108.5 pounds, the Firman P03602 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 67 dBA. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Since the P03602 boasts with a run time of around 14 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable 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.
  • 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. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4500DF, which boasts with a gas consumption of only 0.23 GPH, may be the right generator for you.

Here's a list of the most popular specific comparisons:
