Power & Run Time

The Firman W03081 in use

The Firman W03081

The Firman W03081's core is the 171 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3000W and a peak wattage of 3300W. Additionally, as the generator is parallel capable (Firman parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.

The inverter generator is rated for a noise of 59 dBA (less noisy than rainfall). Its starting mechanism is based on a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 1.8 gallon, the W03081 can operate for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).

As the W03081 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 following 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 allowing you to conveniently charge electronics such as mobile phones and tablets.

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

Portability

As the Firman W03081 is an inverter generator, its encased design (L23.2 x W17.8 x H17.9 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.

As the W03081's weight is only 84 lbs, it can follow you and your power needs anywhere. Moreover, its wheel kit (⌀5") and its folding handle will allow you to effortlessly shift it once it's on the ground.

Features

Panel of the Firman W03081

The W03081's control panel

The W03081'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, when the oil level is too low, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman W03081 also is packed along with the following accessories: funnel, battery charging cables, tool kit and oil.

Emissions

The Firman W03081 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 and therefore, can be used 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 generators of similar power (between 2500 and 3500 W).

  • Regarding its weight, the Firman W03081 only weighs in at 84 pounds, which means it's one of the lighter generators in the 2500-3500 rated wattage range. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • At a lowest noise rating of 59 dBA, this inverter generator is one of the quieter devices of similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
  • As for its autonomy, the W03081, with an autonomy of up to 9 hours at a 25% load, is placed on the low end among the generators of its kind. 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 up to 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. As this inverter generator uses an estimated 0.2 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. 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.

Here's a list of the most popular specific comparisons:
