Zoom on the Firman P03612

In a nutshell, the Firman P03612 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman P03612 in use

The Firman P03612

The Firman P03612 is powered by a 208 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3650W as well as a peak wattage of 4450W.

The generator is rated for a noise of 67 dBA (less noisy than background music). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). For additional convenience, the P03612 may also be remotely started (key fob included).

With a full tank, the P03612 can operate for around 14 hours at 50% load (fuel consumption around 0.36 GPH), thanks to its fuel capacity of 5 gallons.

The quite high THD (<25%) of the P03612 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 4 AC outlets:

Duplex 120V 20A (5-20R)
120/240V 30A (L14-30R) receptacle
120V 30A (TT-30R) receptacle

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready. In addition, due to the featured twist-lock L14-30R receptacle, the P03612 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

With its dimensions of L24.8 x W21.7 x H21.7 in, the conventional, open frame design of the Firman P03612 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 119.5 lbs make it incredibly difficult to manually lift and transport. 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 P03612

The P03612's control panel

The P03612's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

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

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman P03612 also comes with some accessories: tool kit, key fob, oil and funnel are included.

Emissions

The Firman P03612 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.

Product Video

The Firman P03612 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman P03612 compare to generators of similar power (between 3500 and 4500 W).

  • At a weight of 119.5 pounds, the Firman P03612 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 67 dBA. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
  • The P03612 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 Predator 4375, 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. 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 iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman P03612 is on the average side of the price range.

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