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).

  • With a dry weight of 84 lbs, the Firman W03081 falls within the expected weight range for inverter generators in the 2500 to 3500 rated wattage. If weight is a key factor for your needs, the Pulsar PGD40iSCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 46 pounds.
  • With noise levels starting from 58 dBA rating, this inverter generator stands out as one of the quieter options among products of similar type and power. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • Regarding its runtime, the W03081 operates for up to 10 hours at a 25% load, positioning it at the lower spectrum among comparable inverters. If extended autonomy is what matters most to you, the Champion 200977 could be an excellent choice, offering one of the longest run times among units in its power category, reaching up to 22 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.18 GPH (gallon per hour) at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.
