Zoom on the Firman W03383

In a nutshell, the Firman W03383 is a quiet and compact portable inverter generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman W03383 in use

The Firman W03383

The Firman W03383's design includes a gasoline-fueled 193 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3300W and also a peak wattage of 3650W. Moreover, since it is parallel capable (Firman parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.

At a noise rating of 58 dBA (less noisy than a refrigerator), this inverter generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included). For additional convenience, the W03383 may also be remotely started (key fob included).

Thanks to a fuel capacity of 1.8 gallon, the W03383 can operate for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).

The W03383 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Additionally, it features 2 DC outlets: there's a 12V 8A receptacle with which you may charge your batteries with ease and a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets.

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

Portability

The Firman W03383's characteristic encased inverter generator design (L23.2 x W17.8 x H17.9 in), provides an esthetical advantage over any ordinary, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

As the W03383's weight is only 91 lbs, it can follow you and your power needs anywhere. In addition, with its set of 2 wheels (⌀5") and its folding handle, it may be shifted with ease, once placed on the floor.

Features

Panel of the Firman W03383

The W03383's control panel

The W03383's status and activity may be monitored conveniently via the control panel, as it features a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, several light indicators serve to show you when the generator is ready, the oil level is too low and the generator is on overload.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman W03383 also comes with several accessories, including: key fob, battery charging cables, battery charger, tool kit, oil and funnel.

Emissions

The Firman W03383 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

The Firman W03383 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W03383 compare to generators of similar power (between 2500 and 3500 W).

  • At a weight of 91 pounds, the Firman W03383 places in the expected weight range of the generators in the 2500-3500 rated wattage range. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
  • Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. If you are concerned with noise, check out the Honda EU3000iS, which is one of the least noisy generators in its power range, with a noise rating of just 50 dBA.
  • As for its autonomy, the W03383, with an autonomy of up to 9 hours at a 25% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200914, which is able to run for up to 22 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.2 GPH. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.
According to our stats, the following comparison is pretty popular: Firman W03383 vs Firman W03381.

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Firman W03383 is on the average side of the price range.
