Zoom on the Firman P03608
In a nutshell, the Firman P03608 is a portable generator mostly geared towards:
- RV travellers who wish to upgrade their experience to another level
- Homeowners in need of an emergency backup power for their essentials
Power & Run Time
The Firman P03608'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.
The generator is rated for a noise of 68 dBA (less noisy than an office). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). For additional convenience, the P03608 may also be remotely started (key fob included).
With a fuel capacity of 5 gallons, the P03608 may run for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).
Since the P03608 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 upcoming 4 AC outlets:
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
The dimensions of the Firman P03608, which are L24.8 x W21.7 x H21.3 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
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 119.5 lbs. However, this lack of maneuverability is compensated by a wheel kit (⌀8") and a folding handle, with which you can conveniently displace it, once it's on the ground.
The P03608's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with 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.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman P03608 also comes with some accessories: funnel, tool kit, oil and key fob are included.
The Firman P03608 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.
The Firman P03608 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03608 compare to generators of similar power (between 3500 and 4500 W).
- At a weight of 119.5 pounds, the Firman P03608 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.
- As this generator can emit noise as low as 68 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500 with only 52 dBA.
- With a run time of around 14 hours at 50% load, the P03608 has one of the higher run times, compared to its similarly powerful peers. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000, reaching around 16 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman P03608 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
