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
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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 is powered by a 208 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3650W as well as a peak wattage of 4550W.

The generator is rated for a noise of 68 dBA (less noisy than a normal conversation). Its starting mechanism is based on a conventional pull-start mechanism.

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

As the P03602 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

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 P03602 has the following dimensions: L24.8 x W21.7 x H21.3 in. In combination with its conventional, open frame design, they provide support and allow the generator 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, its challenging mobility is solved by a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Firman P03602

The P03602's control panel

The P03602's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display 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.

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.

Besides the classic documentation and a user manual to get you promptly started, the Firman P03602 also comes with some accessories: tool kit, funnel and oil are included.

Emissions

The Firman P03602 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

Moreover, it features a spark arrestor and thus, may 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).

  • At a weight of 108.5 pounds, the Firman P03602 places in the expected weight range of the generators in the 3500-4500 rated wattage range. 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.
  • The generator can be considered average in its noise for its power category, as it is rated at 68 dBA. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Thanks to an impressive running time of around 14 hours at 50% load, the P03602 benefits from a higher run time than many generators of a similar output. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000, 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Firman P03602 vs Firman P03501.

Price comparison

As you can see from this dynamic 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.
