Zoom on the Firman W03383

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

  • RV travellers looking for even more independence
  • 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 buffs looking to enhance their experience

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 W03383 in use

The Firman W03383

The Firman W03383's core is the 193 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3300W and a peak wattage of 3650W. In addition, as it is parallel capable (Firman parallel kit (opens in a new tab) not included), this power can be increased when linked to another similar or compatible unit.

With a noise rating of 58 dBA (less noisy than a conversation at home), the inverter generator features a simple traditional pull-start mechanism, but also a simple and elegant electric starter (battery included). Moreover, to offer you even more convenience, the W03383 can also be remotely started (key fob included).

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

The W03383 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel includes the following 3 AC outlets:

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

It also sports 2 DC outlets: there's a 12V 8A receptacle with which charging your batteries is made easy and a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently.

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

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. Moreover, its set of 2 wheels (⌀5") and its folding handle will allow you to effortlessly shift it once it's on the ground.

Features

Panel of the Firman W03383

The W03383's control panel

The W03383 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, the light indicators show you if the generator is ready, the generator is on overload and its oil levels are insufficient.

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman W03383's package also includes these accessories: battery charger, funnel, tool kit, key fob, oil and battery charging cables.

Emissions

The Firman W03383 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used 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 inverter generators of similar power (between 2500 and 3500 W).

  • Having a dry weight of 91 lbs, the Firman W03383 belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM3300i, with a dry weight of only 47.4 lbs.
  • 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. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • Regarding its autonomy, the autonomy of the W03383, reaching up to 9 hours at a 25% load, can be considered as low end, compared to other inverters of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 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. This inverter generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.2 GPH at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.
According to our stats, the following comparison is pretty popular: Firman W03383 vs Firman W03381.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W inverter 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.
