Zoom on the Firman P03501
In short, the Firman P03501 is a portable generator adequately designed for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- 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.
Power & Run Time
The Firman P03501
The Firman P03501's engine, 208 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3,550W and reaches a peak wattage of 4,450W.
The generator features a standard recoil pull-rope starting mechanism. It is rated for a noise of 67 dBA (less noisy than background music).
Thanks to its 5 gallons fuel tank, the P03501 can run continuously for around 14 hours at 50% load on a full tank (with an average fuel consumption of approximately 0.36 GPH).
The powering of sensitive electronic devices with the P03501 is not recommended due to its high THD (<25%).
Outlets
The control panel features 4 AC outlets as follows:
With its TT-30R receptacle (TT standing for 'Travel Trailer'), this Firman generator is RV Ready, perfectly suited for powering recreational vehicles.
Portability
Measuring L24.8 x W21.7 x H21.7 in, the Firman P03501 showcases a classic open frame layout, guaranteeing stability and simple maintenance access to components, while facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
Despite its weight of 108.5 lbs, the generator is considered 'portable,' signifying its capability to be moved, albeit its heaviness may hinder easy transport. 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 P03501's control panel
The control panel of the P03501 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 shows you if its oil levels are insufficient.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman P03501 ships with supplementary accessories: funnel, oil, cover and tool kit.

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).
- With a dry weight of 108.5 lbs, the Firman P03501 sits comfortably within the expected weight range for devices generating 3500 to 4500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM4600iAEFIC with only 58.4 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 you wish to prioritize minimal noise, the Westinghouse iGen5000DF stands out as one of the quietest options among generators of similar power, with a rating of 52 dBA.
- Compared to devices of similar power, the P03501 stands out with one of the higher run times, lasting around 14 hours at 50% load. If prolonged run time is essential to your needs, you could consider the Predator 4375, which offers one of the highest autonomy among devices with similar power output, lasting around 16 hours.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. As this generator uses an estimated 0.36 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you're placing a high priority on fuel consumption, the Westinghouse iGen5000DF, with a low fuel consumption rate of 0.23 GPH, could be an option to consider.
Price comparison
As you can see from these interactive charts, 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.
