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's design includes a gasoline-fueled 208 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 3,650W and also a peak wattage of 4,450W.

At a noise rating of 67 dBA (less noisy than an office), this generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). The P03612 can also be remotely started, offering further convenience (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 powering of sensitive electronic devices with the P03612 is not recommended due to its high THD (<25%).

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

This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'). In addition, since the P03612 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The Firman P03612 has a conventional, open frame design, of the following dimensions: L24.8 x W21.7 x H21.7 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 119.5 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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

To help you monitor the P03612'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, a light indicator allows you to instantly see if the oil level is too low.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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: tool kit, oil, 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, making it usable 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. In terms of weight, one of the champions in their power range is the Genmax GM4600iAEFIC, standing at just 58.4 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 67 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
  • Since the P03612 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. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4500DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.

Price comparison

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

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
