Power & Run Time

The Firman W03081 in use

The Firman W03081

The Firman W03081 houses a 171 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3000W along with a peak wattage of 3300W. Moreover, since it is parallel capable (Firman parallel kit (opens in a new tab) 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 refrigerator). Its starting mechanism is based on a simple traditional pull-start mechanism.

The fuel capacity of 1.8 gallon allows the W03081 to operate for up to 10 hours with a full tank (fuel consumption around 0.18 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the W03081 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 3 AC outlets:

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

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

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

Portability

The Firman W03081'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 W03081's dry weight of 84 lbs lets you use its power anywhere needed. 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 W03081

The W03081's control panel

To help you monitor the W03081'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, several light indicators serve to show you when the generator is ready, the generator is overloaded and its oil levels are insufficient.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

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: tool kit, funnel, oil and battery charging cables.

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 thus, may be used in forested areas.

Product Video

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 Generac GP3300i, weighing just 59.5 pounds.
  • As its lowest possible noise is rated at 58 dBA, this inverter generator qualifies as one of the more quiet of the products 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.
  • Autonomy-wise, with up to 10 hours on a full tank at a 25% load, the W03081 is on the low end when compared to other generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching up to 22 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency 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 you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3500P, with a fuel consumption of 0.13 GPH could be in your good books.

Price comparison

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