Zoom on the Firman P03601
In a nutshell, the Firman P03601 is a compact portable generator mostly geared towards:
- RV travellers looking for even more independence
- 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, including its emission compliance information.
Power & Run Time
The Firman P03601's engine, 208 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3650W and reaches a peak wattage of 4550W.
With a noise rating of 68 dBA (less noisy than a normal conversation), the generator features a conventional pull-start mechanism.
The P03601 can operate for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH), due to its fuel capacity of 5 gallons.
Since the P03601 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the following 4 AC outlets:
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.
The design of the Firman P03601 is a typical, open frame, with the dimensions of L23.2 x W17.5 x H18.5 in, offering support and stability and enabling the possibility of raising it above ground level. The featured design is ideal for the outdoors and all tough environments.
As the generator's weight is 101.5 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable).
The P03601's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.
In addition to this info, a light indicator serves to show you when 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 standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
Apart from the typical documentation and a user manual, which lets you start it right away, the Firman P03601 also is packed along with the following accessories: funnel, oil and tool kit.
The Firman P03601 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
Moreover, it features a spark arrestor, making it usable in forested areas.
The Firman P03601 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03601 compare to generators of similar power (between 3500 and 4500 W).
- As far as its dry weight is concerned, the Firman P03601 weighs just 101.5 pounds and thus, it is one of the lighter 3500 to 4500 rated wattage generators. In terms of weight, one of the champions in their power range is the Energizer eZV4500, standing at just 78 lbs.
- This generator has a somewhat average expected noise for its power range, rated at 68 dBA. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- With a run time of 14 hours at 50% load, the P03601 has one of the higher run times, compared to its similarly powerful peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000, which is able to run for 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. 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 wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.
As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Firman P03601 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Several accessories included
- RV Ready
- Lightweight for its kind (101.5 lbs)
- High run time
- Acceptable noise (68 dBA)
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
