In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.
Power & Run Time
Running on gasoline, the Firman W03381 utilizes a 193 cc Firman Max-Pro Series OHV 4-stroke engine with cast iron sleeve to deliver 120V, offering a running wattage of 3,300W and a starting wattage of 3,650W. Furthermore, its parallel capability (Firman parallel kit (opens in a new tab) not included) allows power output to increase 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 rainfall), the inverter generator's starting mechanism is centered around a manual recoil starter system.
Featuring a 1.8 gallon fuel tank, the W03381 provides continuous power for up to 10 hours on a full tank (fuel consumption around 0.18 GPH).
The W03381 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 features 3 AC outlets as follows:
In addition, it provides 2 DC outlets: there's a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently and a 12V 8A receptacle providing easy battery charging capabilities.
With its TT-30R receptacle (TT standing for 'Travel Trailer'), this Firman generator is RV Ready, perfectly suited for powering recreational vehicles.
Portability
Since the Firman W03381 is an inverter generator, its closed design (L23.2 x W17.8 x H17.9 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.
Weighing 87 lbs, the W03381 is practical, ensuring it can follow you wherever power is required. Moreover, its set of 2 wheels (⌀5") and its folding handle will allow you to easily shift it once it's on the ground.
Features
To help you monitor the W03381's status and activity, its control panel is equipped with a convenient meter, offering voltage, frequency, and lifetime hours readings.
In addition to this info, light indicators on the device will signal if the oil level is too low, the generator is on overload and the generator is ready.
Considering security aspects, the generator boasts an overload protection (circuit breaker) and an automatic low oil shut-off, offering peace of mind throughout operation.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman W03381 also comes with some accessories: oil, tool kit, funnel and battery charging cables are included.

The Firman W03381 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman W03381 compare to inverter generators of similar power (between 2500 and 3500 W).
- At 87 lbs in dry weight, the Firman W03381 fits well within the typical weight bracket for inverter generators producing 2500 to 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PGD40iSCO, with a dry weight of only 46 lbs.
- With a noise rating as low as 58 dBA, this inverter generator is among the quieter options available in its type and power range. 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.
- Regarding its autonomy, the autonomy of the W03381, 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 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.
- Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. The inverter generator utilizes approximately 0.18 GPH of gasoline at a 25% load, placing it within the typical range of fuel consumption seen in products of comparable wattage. If gasoline efficiency is at the top of your list, you may want to have a look at the Energizer eZV3500P, which has great fuel efficiency, with a gas consumption of only 0.13 gallons per hour.
Here's a list of the most popular specific comparisons:
