Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.
Power & Run Time
The Firman W02981 is powered by a 171 cc Firman Max-Pro Series OHV 4-stroke engine with cast iron sleeve. It delivers 120V, runs on gasoline and offers a running wattage of 2,900W as well as a peak wattage of 3,200W. Furthermore, its parallel capability (Firman parallel kit (opens in a new tab) not included) allows power output to double when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
With a noise rating of 58 dBA (less noisy than a refrigerator), the inverter generator's ignition is facilitated by a classic hand-operated recoil starting 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).
The W02981 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel is equipped with the following 3 AC outlets:
Moreover, it comes equipped with 2 DC outlets: there's a 12V 8A receptacle making battery charging a breeze and a 5V USB port enabling convenient charging of devices like mobile phones and tablets.
The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Firman generator RV Ready, ideal for providing power to recreational vehicles.
Portability
Thanks to its closed inverter generator design (L23.2 x W17.8 x H17.9 in), the Firman W02981 not only offers superior aesthetics but also operates with reduced noise levels compared to a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.
As the W02981's weight is only 84 lbs, it can follow you and your power needs anywhere. Additionally, it can be easily moved with the help of its set of 2 wheels (⌀5") and its folding handle, once it is on the ground.
Features
The W02981's status and activity may be monitored conveniently via the control panel, as it features a convenient meter, showing voltage, frequency, and lifetime hours metrics.
In addition to this info, light indicators on the device will notify you if the generator is on overload, the oil level is too low and the generator is ready.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.
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: tool kit, funnel, battery charging cables 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).
- With a dry weight of 84 lbs, the Firman W02981 falls within the expected weight range for inverter generators in the 2500 to 3500 rated wattage. if you wish to prioritize weight, the Pulsar PGD40iSCO is one of the top contenders in its power category, weighing only 46 pounds.
- Delivering a rated noise output as low as 58 dBA, this inverter generator is has a quieter operation that most units of similar type and power. 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.
- Regarding its autonomy, the autonomy of the W02981, reaching up to 10 hours at a 25% load, can be considered as low end, compared to other inverters of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200977, boasting with up to 22 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. 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're placing a high priority on fuel consumption, the Energizer eZV3500P, with a low fuel consumption rate of 0.13 GPH, could be an option to consider.
