Description
Zoom on the Firman P03613
To sum up, the Firman P03613 is a portable generator tailored for:
- 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
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
The Firman P03613 houses a 208 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3,650W along with a peak wattage of 4,550W.
Enjoying a noise rating of 67 dBA (less noisy than background music), this generator gets running thanks to a traditional recoil pull-start mechanism.
With its 5 gallons fuel tank, the P03613 can operate for around 14 hours at 50% load when fully fueled (with fuel usage averaging around 0.36 GPH).
As the P03613 has a high THD (<25%), it is not recommended to use it to power sensitive electronic devices.
Outlets
The control panel features the following 4 AC outlets:
With its TT-30R receptacle (TT standing for 'Travel Trailer'), this Firman generator is RV Ready, perfectly suited for powering recreational vehicles.
Portability
With dimensions of L24.8 x W21.7 x H21.7 in, the traditional open frame design of the Firman P03613 ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The generator is designed for ideal use outdoors and in rough environments.
As the generator's weight is 108.5 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the lack of maneuverability can be offset with its wheel kit (⌀8") and its folding handle, which allows for convenient shifting once the generator is placed on the ground.
Features
The control panel of the P03613 is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings, aiding in monitoring its status and activity.
In addition to this info, a light indicator on the device will notify you if its oil levels are insufficient.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
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.
The P03613 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P03613's package also includes these accessories: oil, tool kit and funnel.

The Firman P03613 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman P03613 compare to generators of similar power (between 3500 and 4500 W).
- With a dry weight of 108.5 pounds, the Firman P03613 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. if you wish to prioritize weight, the Genmax GM4600iAEFIC is one of the top contenders in its power category, weighing only 58.4 pounds.
- The generator's noise output, rated at 67 dBA, falls within the average range expected for devices in its power range. 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 iGen5000DF, whose lowest noise levels reach just 52 dBA.
- The P03613 provides a higher run time than similarly powerful devices, reaching around 14 hours at 50% load. 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.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. 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. To prioritize fuel savings, we advise considering the Westinghouse iGen5000DF, which stands out for its gasoline efficiency, consuming just 0.23 gallons per hour.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W generators, the Firman P03613 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.
