Zoom on the Firman P03608
In a nutshell, the Firman P03608 is a portable generator mostly geared towards:
- RV travellers looking for even more independence
- 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
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Firman P03608's core is the 208 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3650W and a peak wattage of 4550W.
The generator is rated for a noise of 67 dBA (less noisy than a normal conversation). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included). For additional convenience, the P03608 may also be remotely started (key fob included).
With a full tank, the P03608 can operate for around 14 hours at 50% load (fuel consumption around 0.36 GPH), thanks to its fuel capacity of 5 gallons.
The quite high THD (<25%) of the P03608 makes it unsuitable for powering sensitive electronic devices.
The control panel provides the upcoming 4 AC outlets:
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
The dimensions of the Firman P03608, which are L24.8 x W21.7 x H21.7 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 119.5 pounds. However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.
To help you monitor the P03608's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
In addition to this info, when the oil level is too low, you will be informed by the featured light indicator.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
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.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman P03608 also comes with several accessories, including: funnel, tool kit, key fob and oil.
The Firman P03608 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may 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).
- As its weight is 119.5 pounds, the Firman P03608 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 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 are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
- The P03608 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides around 16 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.36 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Firman P03608 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
- Remote start
- High run time
- Decent weight (119.5 lbs)
- Acceptable noise (67 dBA)
- Decent fuel efficiency
The Firman P03608 doesn't have any notably low specs.
