Description
Zoom on the Firman P03602
In a nutshell, the Firman P03602 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
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 P03602
The Firman P03602 houses a 208 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3650W along with a peak wattage of 4550W.
At a noise rating of 68 dBA (less noisy than background music), the generator offers the possibility to start the device via a conventional pull-start mechanism.
The fuel capacity of 5 gallons allows the P03602 to operate 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 P03602 is not recommended due to its relatively high THD (<25%).
- For camping/tailgating: 1 toaster oven, 1 rice cooker, 1 coffee maker, 1 blender and 1 slow cooker
- At home: 1 toaster oven, 1 waffle iron, 1 rice cooker, 1 blender, 1 radio and 1 cell phone charger
- For work: 1 drill, 1 electric fence (25 miles), 1 drain cleaner and 1 bug zapper
Outlets
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.
Portability
The design of the Firman P03602 is a typical, open frame, with the dimensions of L24.8 x W21.7 x H21.3 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.
Since the generator weighs 108.5 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). However, its challenging mobility is solved by a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.
Features
The P03602's control panel
To help you monitor the P03602's status and activity, its control panel is equipped with a convenient meter, which displays 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 generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
Apart from the typical documentation and a user manual, which lets you start it right away, the Firman P03602 also is packed along with the following accessories: oil, funnel and tool kit.
Emissions
The Firman P03602 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
Moreover, it features a spark arrestor and therefore, can be used in forested areas.
Product Video
The Firman P03602 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03602 compare to generators of similar power (between 3500 and 4500 W).
- Regarding its weight, the Firman P03602 only weighs in at 108.5 pounds, which means it's one of the lighter generators in the 3500-4500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Energizer eZV4500, weighing just 78 pounds.
- Because this generator emits noise as low as 68 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500, whose lowest noise levels reach just 52 dBA.
- As the P03602 features an autonomy of 14 hours at 50% load, it has a higher run time than an average generator of its power range. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000, reaching 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 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.
Price comparison
As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Firman P03602 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.

- Several accessories included
- RV Ready
- Lightweight for its kind (108.5 lbs)
- High run time
- Acceptable noise (68 dBA)
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
