Zoom on the Firman P03612

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

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's build contains a gasoline-fueled 208 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3650W and also a peak wattage of 4450W.

With a noise rating of 67 dBA (less noisy than background music), the generator features a conventional pull-start mechanism, but also a simple and elegant electric starter (battery included). For additional convenience, the P03612 may also be remotely started (key fob included).

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

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

The generator will allow you to simultaneously power various devices, for example:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

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 dimensions of the Firman P03612, which are L24.8 x W21.7 x H21.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 119.5 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Never less, thanks to a wheel kit (⌀8") and a folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The P03612's control panel

The P03612 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

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

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

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Apart from the typical documentation and a user manual, which lets you start it right away, the Firman P03612 also is packed along with the following accessories: oil, key fob, funnel and tool kit.

Emissions

The Firman P03612 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 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 Energizer eZV4500, with a dry weight of just 78 pounds.
  • 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 iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As the P03612 features an autonomy of 14 hours at 50% load, it has a higher run time than an average generator of its power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000, boasting with 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 average fuel consumption among comparably powerful devices, as it reaches 0.36 GPH (gallon per hour) at a 50% load. 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.

Price comparison

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