Power & Run Time

The Firman P03612 in use

The Firman P03612

The Firman P03612's engine, 208 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3,650W and reaches a peak wattage of 4,450W.

Featuring a noise rating of 67 dBA (less noisy than an office), the generator is equipped with both a classic hand-operated recoil starting mechanism and a user-friendly and hassle-free electric starter (battery included) for starting. Furthermore, for added convenience, the P03612 offers remote starting capabilities (key fob included).

The P03612 boasts a fuel tank capable of holding 5 gallons, allowing it to run continuously for around 14 hours at 50% load (with fuel usage averaging around 0.36 gallons per hour).

As the P03612 exhibits a THD of less than 25%, which is high, it is best avoided for powering sensitive electronic devices.

Outlets

The control panel features 4 AC outlets as follows:

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

Thanks to its TT-30R receptacle (TT meaning 'Travel Trailer'), this Firman generator is RV Ready, ready to power your recreational vehicle with ease. 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

At L24.8 x W21.7 x H21.7 in, the Firman P03612 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 119.5 lbs. Still, once it is on the ground, its wheel kit (⌀8") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the Firman P03612

The P03612's control panel

The control panel of the P03612 is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings, aiding in monitoring its status and activity.

In addition to this info, a light indicator on the device will signal 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.

Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.

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: oil, funnel, tool kit and key fob are included.

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).

  • Weighing in at 119.5 lbs, the Firman P03612 fits within the expected weight range for devices producing 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the Genmax GM4600iAEFIC, weighing just 58.4 pounds.
  • With noise emissions rated as low as 67 dBA, this generator falls within the typical noise range expected for devices of similar power. If you'd like a less noisy alternative, the Westinghouse iGen4500DF is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
  • As the P03612 features an autonomy of around 14 hours at 50% load, it has a higher run time than an average generator of its power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides around 16 hours.
  • While run time matters, it's heavily influenced by the fuel tank's capacity. Hence, it's important to consider fuel efficiency alongside. With a fuel usage of about 0.36 GPH at a 50% load, this generator falls within the typical gasoline consumption range observed in comparably powerful products. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4500DF, which boasts with a gas consumption of only 0.23 GPH, may be the right generator for you.
