Description
Zoom on the Firman P03612
In summary, the Firman P03612 is a portable generator especially useful for:
- 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
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
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 3650W and reaches a peak wattage of 4450W.
The generator is rated for a noise of 67 dBA (less noisy than background music). Its starting mechanisms include a conventional pull-start mechanism and a simple and elegant electric starter (battery included). To add further convenience, the P03612 can 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 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:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready. In addition, as it features a twist-lock L14-30R receptacle, the P03612 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
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 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. 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
The P03612's control panel
To help you monitor the P03612's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
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 overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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: 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.
However, it features a spark arrestor, which makes it suitable for use in forested areas.
Product Video
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 weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing 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 Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 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.
- 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. 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 you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you could look out for.
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.

- Several accessories included
- RV Ready
- Remote start
- High run time
- Decent weight (119.5 lbs)
- Acceptable noise (67 dBA)
- Decent fuel efficiency
