It’s ergonomic encasing and integrated wheel kit makes it easy to transport for those weekend camping getaways. (source: Firman (opens in a new tab))

Zoom on the Firman W03081

In a nutshell, the Firman W03081 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 sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 W03081 in use

The Firman W03081

The Firman W03081 is powered by a 171 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,000W as well as a peak wattage of 3,300W. 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.

The inverter generator is rated for a noise of 58 dBA (less noisy than a conversation at home). Its starting mechanism is based on a simple traditional pull-start mechanism.

With a fuel capacity of 1.8 gallon, the W03081 may run for up to 10 hours with a full tank (fuel consumption around 0.18 GPH).

The W03081 produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.

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 you may charge electronics, for example mobile phones or tablets, conveniently.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.

Portability

Thanks to its closed inverter generator design (L23.2 x W17.8 x H17.9 in), the Firman W03081, is more esthetical than a typical, open frame generator. This modern design aims to provide an ideal power solution to recreational users.

The 84 lbs of the W03081's dry weight enables you to use it anywhere you will ever need. In addition, with its set of 2 wheels (⌀5") and its folding handle, it may be shifted with ease, once placed on the floor.

The W03081's control panel

The W03081's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

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

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman W03081 also comes with several accessories, including: tool kit, funnel, oil and battery charging cables.

Emissions

The Firman W03081 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 W03081 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W03081 compare to inverter generators of similar power (between 2500 and 3500 W).

  • With a dry weight of 84 pounds, the Firman W03081 finds itself in the expected weight range for inverter generators able to produce between 2500 and 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
  • With a lowest possible noise of 58 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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.
  • The W03081's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 10 hours at 25% load on a full tank. 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.
  • 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. Standing at an estimated 0.18 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, 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 inverter generators, the Firman W03081 is on the average side of the price range.

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