Description

Zoom on the Firman W03381

In a nutshell, the Firman W03381 is a quiet and compact portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • 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 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 W03381 is powered by a 193 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3300W as well as a peak wattage of 3650W. Moreover, since it is parallel capable (Firman parallel kit not included), its power may be doubled if linked to a second compatible unit.

The inverter generator is rated for a noise of 58 dBA (less noisy than a conversation at home). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included). To add further convenience, the W03381 can be remotely started (key fob included).

Thanks to a fuel capacity of 1.8 gallon, the W03381 can operate for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).

The W03381 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Several examples of what the generator may allow you to power simultaneously are:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel includes the following 3 AC outlets:

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

Furthermore, it has 2 DC outlets: there's a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle allowing you to easily charge your batteries.

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

Portability

The Firman W03381'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 W03381's dry weight of 87 lbs lets you use its power anywhere needed. Furthermore, once placed on the floor, effortless displacement is possible with a wheel kit (⌀5") and a folding handle.

Features

To help you monitor the W03381'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, the light indicators show you if the generator is on overload, the generator is ready and its oil levels are insufficient.

From a security point of view, the generator is equipped with an automatic low oil shut-off, giving you a peace of mind during use.

While the standard documentation and a user manual, helpful for starting the device promptly, come with the Firman W03381, the following accessories are also included: key fob, tool kit, battery charging cables, funnel and oil.

Emissions

The Firman W03381 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, making it usable in forested areas.

The Firman W03381 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W03381 compare to generators of similar power (between 2500 and 3500 W).

  • As far as its dry weight is concerned, the Firman W03381 weighs just 87 pounds and thus, it is one of the lighter 2500 to 3500 rated wattage generators. In terms of weight, one of the champions in their power range is the Honda EG2800i, standing at just 66.6 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. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
  • The autonomy is somewhat low end compared to devices of its power range, as it reaches only 9 hours at 25% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EU3000iS, boasting with 20 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.2 GPH at a 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3200P, with a fuel consumption of 0.13 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 2500-3500W generators, the Firman W03381 is on the average side of the price range.

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