Power & Run Time

The Firman W03081 in use

The Firman W03081

The Firman W03081's build contains a gasoline-fueled 171 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3000W and also a peak wattage of 3300W. Additionally, as the generator is parallel capable (Firman parallel kit not included), it can be linked to a second unit for more power.

With a noise rating of 59 dBA (less noisy than a refrigerator), the inverter generator features a simple traditional pull-start mechanism.

The fuel capacity of 1.8 gallon allows the W03081 to operate for up to 9 hours with a full tank (fuel consumption around 0.2 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).

Here are a few examples of what this generator could allow you to simultaneously power:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel features the upcoming 3 AC outlets:

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

Additionally, it features 2 DC outlets: there's a 12V 8A receptacle with which charging your batteries is made easy and a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.

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. The featured design follows the latest trends and is ideal for easy and recreational use.

The W03081's dry weight of 84 lbs lets you use its power anywhere needed. In addition, with a wheel kit (⌀5") and a folding handle, it may be displaced with ease, once placed the floor.

The W03081's control panel

To help you monitor the W03081's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, when the generator is ready, the generator is overloaded and the oil level is too low, you will be informed by the featured light indicators.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

Besides the classic documentation and a user manual to get you promptly started, the Firman W03081 also comes with some accessories: tool kit, oil, funnel and battery charging cables are included.

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).

  • Weight-wise, the Firman W03081 has only 84 lbs, which renders it one of the lighter generators which produce 2500 to 3500 rated watts. If weight is your top priority, one of the champions in this power category is the Honda EG2800i, weighing just 66.6 pounds.
  • With a lowest possible noise of 59 dBA, this inverter generator places itself amongst the more quiet of the products delivering 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.
  • Regarding its autonomy, the autonomy of the W03081, reaching 9 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EU3000iS, reaching 20 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.2 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3200P is a device you should look out for.

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

Price comparison

As you can see from this dynamic chart, when compared to other 2500-3500W generators, the Firman W03081 is on the average side of the price range.
