This generator has an ergonomic handle and never-flat wheels for easy transport during those weekend camping getaways or portable backup power. It features 4550 starting watts and 3650 running watts, with a recoil, electric and remote start system for ease of use. (source: Firman)

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
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

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 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 a normal conversation), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included). For additional convenience, the P03612 may also be remotely started (key fob included).

The P03612 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.

The P03612 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).

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

With its TT-30R receptacle (TT as in '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 featured design is ideal for the outdoors and all tough 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 a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Firman P03612

The P03612's control panel

The P03612's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, which displays voltage, frequency and lifetime hours.

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.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, 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: key fob, funnel, tool kit and oil.

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).

  • With a dry weight of 119.5 pounds, the Firman P03612 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. 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.
  • As this generator can emit noise as low as 67 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Thanks to an impressive running time of around 14 hours at 50% load, the P03612 benefits from a higher run time than many generators of a similar output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000, as it provides around 16 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 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 cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
