Description
Zoom on the Firman P03608
In summary, the Firman P03608 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
The Firman P03608
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 features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 67 dBA (less noisy than a normal conversation). 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).
The P03608 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<25%).
Outlets
The control panel includes the following 4 AC outlets:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.
Portability
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.
Since the generator weighs 119.5 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). 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 P03608's control panel
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, a light indicator allows you to instantly see if the oil level is too low.
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 overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to 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, key fob, tool kit and oil are included.
Emissions
The Firman P03608 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, making it usable 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).
- With a dry weight of 119.5 pounds, the Firman P03608 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- Since the generator's noise is rated at 67 dBA, it has the roughly average expected noise for a device of similar 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.
- Thanks to an impressive running time of around 14 hours at 50% load, the P03608 benefits from a higher run time than many generators of a similar output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.36 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned 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 could look out for.
Price comparison
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.
The bottom line
- In the expected price range
- 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.
