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
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman P03602 in use

The Firman P03602

The Firman P03602's core is the 208 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3650W and a peak wattage of 4550W.

With a noise rating of 67 dBA (less noisy than a normal conversation), the generator features a simple traditional 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).

The quite high THD (<25%) of the P03602 makes it unsuitable for powering 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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.

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, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Firman P03602

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 serves to show you when its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman P03602, the following accessories are also included: oil, tool kit 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, which makes it suitable 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).

  • Having a dry weight of 108.5 lbs, the Firman P03602 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • This generator has a somewhat average expected noise for its power range, rated at 67 dBA. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As the P03602 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.
  • 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. This generator has an estimated fuel consumption of roughly 0.36 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Cummins Onan P4500i is a device you could look out for.
According to our stats, the following comparison is pretty popular: Firman P03602 vs Firman P03501.

Price comparison

As you can see from this interactive 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.
