Description
Zoom on the Firman P03501
In a nutshell, the Firman P03501 is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman P03501's design includes a gasoline-fueled 208 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3,550W and also a peak wattage of 4,450W.
With a noise rating of 67 dBA (less noisy than an office), the generator features a conventional pull-start mechanism.
With a fuel capacity of 5 gallons, the P03501 may run for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).
The P03501 is unsuitable for the powering of sensitive electronic devices due to its high THD (<25%).
Outlets
The control panel features the upcoming 4 AC outlets:
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.
Portability
The Firman P03501 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 generator is designed for ideal use outdoors and in rough environments.
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 108.5 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
The control panel of the P03501 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
In addition to this info, a light indicator shows you 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.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman P03501 also is packed along with the following accessories: oil, funnel, cover and tool kit.
Emissions
The Firman P03501 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.

The Firman P03501 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03501 compare to generators of similar power (between 3500 and 4500 W).
- At a weight of 108.5 pounds, the Firman P03501 places in the expected weight range of the generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- The generator can be considered average in its noise for its power category, as it is 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.
- Thanks to an impressive running time of around 14 hours at 50% load, the P03501 benefits from a higher run time than many generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching 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 has an estimated fuel consumption of roughly 0.36 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF 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 P03501 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
- High run time
- Decent weight (108.5 lbs)
- Acceptable noise (67 dBA)
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
