Power & Run Time

The Firman W02981 in use

The Firman W02981

Running on gasoline, the Firman W02981 utilizes a 171 cc Firman Max-Pro Series OHV 4-stroke engine to deliver 120V, offering a running wattage of 2,900W and a starting wattage of 3,200W. In addition, as it is parallel capable (Firman parallel kit (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

With a noise rating of 58 dBA (less noisy than rainfall), the inverter generator's starting mechanism is centered around a simple traditional pull-start mechanism.

Featuring a 1.8 gallon fuel tank, the W02981 can provide power for up to 10 hours on a full tank (with fuel consumption averaging 0.18 gallons per hour).

Delicate electronics can be plugged in the AC outlets safely, as the W02981 generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel provides the upcoming 3 AC outlets:

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

It also sports 2 DC outlets: there's a 12V 8A receptacle providing easy battery charging capabilities and a 5V USB port enabling convenient charging of devices like 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 W02981 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. This type of design is the most modern and convenient way to recreationally generate power.

The W02981's dry weight of 84 lbs lets you use its power anywhere needed. Moreover, its set of 2 wheels (⌀5") and its folding handle make it easy to shift the generator once it's on the ground.

Features

The W02981's control panel

The control panel of the W02981 is equipped with a convenient meter, displaying voltage, frequency, and lifetime hours information, aiding in monitoring its status and activity.

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

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Firman W02981 ships with supplementary accessories: battery charging cables, funnel, tool kit and oil.

The Firman W02981 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W02981 compare to inverter generators of similar power (between 2500 and 3500 W).

  • At 84 lbs in dry weight, the Firman W02981 fits well within the typical weight bracket for inverter generators producing 2500 to 3500 rated watts. Weight-conscious users may find the Pulsar PGD40iSCO appealing, as it is one of the top contenders in this power range, weighing just 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. If noise level is one your key decisive factors, you may find the Honda EU3000iS appealing. It's rated at 50 dBA, making it one of the quietest generators in its power range.
  • Concerning its runtime, the W02981 provides up to 10 hours at a 25% load, indicating that it falls on the lower side compared to other generators of its type and power range. If wyou wish to prioritize autonomy, the Champion 200914 shines as one of the top contenders, offering one of the highest run times among generators with similar power output, totaling 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. With a fuel usage of about 0.18 GPH at a 25% load, this inverter generator falls within the typical gasoline consumption range observed in comparably powerful products. 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.

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

Price comparison

As you can see from these interactive charts, when compared to other 2500-3500W inverter generators, the Firman W02981 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

Oil capacity is 20.3 oz.

Does this invertor have an inline gas shut off? (Asked October 03, 2021)
