Firman P03602 Spec Review

Description

Zoom on the Firman P03602

In summary, the Firman P03602 is a portable generator especially useful 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, including its emission compliance information.

Power & Run Time

The Firman P03602

The Firman P03602'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.

Enjoying a noise rating of 67 dBA (less noisy than background music), this generator gets running thanks to a conventional pull-start mechanism.

With a fuel capacity of 5 gallons, the P03602 may run for around 14 hours at 50% load with a full tank (fuel consumption around 0.36 GPH).

As the P03602 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel provides the upcoming 4 AC outlets:

Duplex 120V 20A (5-20R)

120V 30A (L5-30R) receptacle

120V 30A (TT-30R) receptacle

This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Firman P03602 has the following dimensions: L24.8 x W21.7 x H21.7 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough 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 108.5 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.

Features

The P03602's control panel

The P03602 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman P03602's package also includes these accessories: tool kit, oil and funnel.

Emissions

The Firman P03602 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

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).

• As its weight is 108.5 pounds, the Firman P03602 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
• This generator has a somewhat average expected noise for its power range, rated at 67 dBA. 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 P03602 benefits from a higher run time than many generators of a similar output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for around 16 hours.
• The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
