Zoom on the Firman P03612

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

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • 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 P03612 in use

The Firman P03612

The Firman P03612 houses a 208 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3,650W along with a peak wattage of 4,450W.

With a noise rating of 67 dBA (less noisy than an office), the generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the P03612 can also be remotely started (key fob included).

The fuel capacity of 5 gallons allows the P03612 to operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

As the P03612 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the following 4 AC outlets:

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

This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, as the P03612 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home 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 generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 119.5 pounds. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Firman P03612

The P03612's control panel

To help you monitor the P03612's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

In addition to this info, a light indicator shows you if its oil levels are insufficient.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P03612 also is packed along with the following accessories: oil, tool kit, key fob and funnel.

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 and therefore, can be used in forested areas.

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).

  • As its weight is 119.5 pounds, the Firman P03612 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. 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.
  • Because this generator emits noise as low as 67 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • With a run time of around 14 hours at 50% load, the P03612 has one of the higher run times, compared to its similarly powerful peers. 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. This generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4500DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.

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.
