Description
Zoom on the Firman P03612
In summary, the Firman P03612 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners in need of an emergency backup power for their essentials
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
The Firman P03612's core is the 208 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3650W and a peak wattage of 4450W.
The generator features a simple traditional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 67 dBA (less noisy than a normal conversation). 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).
Since the P03612 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel includes the following 4 AC outlets:
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
The Firman P03612 has the following dimensions: L24.8 x W21.7 x H21.7 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
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. 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
The P03612's control panel
The P03612's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
In addition to this info, the device’s light indicator will display if the oil level is too low.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P03612's package also includes these accessories: oil, key fob, tool kit 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).
- Having a dry weight of 119.5 lbs, the Firman P03612 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- 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.
- 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. 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.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned 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.
The bottom line
- In the expected price range
- Several accessories included
- RV Ready
- Remote start
- High run time
- Decent weight (119.5 lbs)
- Acceptable noise (67 dBA)
- Decent fuel efficiency
- Not CARB-compliant
