In summary, the Firman W03383 is a quiet and compact portable inverter generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating buffs looking to enhance their experience

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 W03383 in use

The Firman W03383

The Firman W03383 houses a 193 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3300W along with a peak wattage of 3650W. In addition, the device is parallel capable (Firman parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.

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

With a full tank, the W03383 can operate for up to 10 hours (fuel consumption around 0.18 GPH), thanks to its fuel capacity of 1.8 gallon.

As the W03383 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the upcoming 3 AC outlets:

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

In addition, it provides 2 DC outlets: there's a 12V 8A receptacle allowing you to easily charge your batteries and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

Thanks to its TT-30R receptacle (TT stands for '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. This modern design aims to provide an ideal power solution to recreational users.

The 91 lbs of the W03383's dry weight enables you to use it anywhere you will ever need. Furthermore, once placed on the floor, effortless displacement is possible thanks to its set of 2 wheels (⌀5") and its folding handle.

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, which displays voltage, frequency and lifetime hours.

In addition to this info, some light indicators allow you to instantly see if the generator is ready, the oil level is too low and the generator is on overload.

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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman W03383 also comes with some accessories: battery charging cables, tool kit, oil, funnel, key fob and battery charger are included.

Emissions

The Firman W03383 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use 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).

  • As far as its dry weight is concerned, the Firman W03383 weighs just 91 pounds and thus, it is one of the lighter 2500 to 3500 rated wattage generators. If weight is your top priority, one of the champions in this power category is the Generac GP3300i, weighing just 59.5 pounds.
  • With a lowest noise rating of 58 dBA, the inverter generator is one of the more quiet of the generators of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
  • Regarding its autonomy, the autonomy of the W03383, reaching up to 10 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200954, which is able to run for up to 22 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This inverter generator has an estimated fuel consumption of roughly 0.18 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3200P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

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.

Therefore, this generator nicely fits in the expected budget for this kind of product.
