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 3,000W and a peak wattage of 3,300W. Moreover, the parallel capability (Firman parallel kit (opens in a new tab) not included) enables power output to double when paired with another similar or compatible unit, providing increased energy capacity and versatility for a wide range of needs.

Enjoying a noise rating of 58 dBA (less noisy than a refrigerator), this inverter generator gets running thanks to a manual recoil starter system.

The W03081's fuel tank holds 1.8 gallon, ensuring uninterrupted operation for up to 10 hours with a full tank (fuel consumption approximately 0.18 GPH).

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

Outlets

The control panel features 3 AC outlets as follows:

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

Moreover, it comes equipped with 2 DC outlets: there's a 12V 8A receptacle providing easy battery charging capabilities and a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets.

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

Portability

As an inverter generator, the Firman W03081 showcases a closed design (L23.2 x W17.8 x H17.9 in), enhancing aesthetics and ensuring quieter operation compared to conventional, open frame models. The featured design follows the latest trends and is ideal for easy and recreational use.

With a dry weight of 84 lbs, the W03081 is convenient, ensuring it can be taken wherever power is needed. Furthermore, once placed on the floor, simple 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

Included in the control panel of the W03081 are a convenient meter, which displays voltage, frequency and lifetime hours, essential for monitoring its status and activity.

In addition to this info, when its oil levels are insufficient, the generator is ready and the generator is overloaded, 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.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman W03081 ships with supplementary accessories: battery charging cables, oil, tool kit and funnel.

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).

  • Having a dry weight of 84 lbs, the Firman W03081 belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • This inverter generator offers a rated noise level of 58 dBA, placing it among the quieter alternatives in its type and power category. If you'd like a less noisy alternative, the Honda EU3000iS is a strong contender. It boasts a noise rating of 50 dBA, placing it among the quietest generators in its power category.
  • In terms of autonomy, the W03081 offers up to 10 hours at a 25% load, placing it at the lower range within its type and power range. If run time is one of your main concerns, the Champion 200977 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting up to 22 hours.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. 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 get a unit of similar power, but with one of the best fuel efficiency, you could consider the Energizer eZV3500P, which has an impressively low fuel consumption of 0.13 GPH.

Price comparison

As you can see from these interactive charts, 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.
