Firman P03613 - 3650/4550W Portable Generator

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

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:

Duplex 120V 20A (5-20R)

120V 30A (L5-30R) receptacle

120V 30A (TT-30R) receptacle

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 P03613's control panel

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).

• Weighing in at 108.5 lbs, the Firman P03613 fits within the expected weight range for devices producing 3500 to 4500 rated watts. If weight is an important consideration for you, the Genmax GM4600iAEFIC stands out as one of the top contenders in this power category, with a dry weight of 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 are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
• As the P03613 features an autonomy of around 14 hours at 50% load, it has a higher run time than an average generator of its power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 hours.
• Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. When operating at 50% load, the generator's fuel consumption is estimated at 0.36 GPH, placing it within the average range of gasoline usage among similarly powerful devices. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF is a device you could look out for.
