Zoom on the Firman P03601
In summary, the Firman P03601 is a compact portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- 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
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.
At a noise rating of 67 dBA (less noisy than background music), the generator is started via a conventional pull-start mechanism.
With a fuel capacity of 5 gallons, the P03601 may run for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).
The powering of sensitive electronic devices with the P03601 is not recommended due to its relatively high THD (<25%).
The control panel provides the upcoming 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 W17.8 x H18.6 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Since the generator weighs 101.5 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). The additional purchase of an official wheel kit (opens in a new tab) can therefore be a good idea, if you wish to improve the generator's mobility.
The control panel of the P03601 includes a convenient meter showing you 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.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman P03601 also comes with some accessories: funnel, tool kit and oil are included. An official storage cover is also available, as a separate purchase.
The Firman P03601 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 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. 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. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
- Since the P03601 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 Honda EB4000X, 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. This generator reaches an estimated fuel consumption of 0.36 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned 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 should look out for.
As you can see from this interactive 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.
