In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Firman W03381
The Firman W03381 is powered by a 193 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3300W as well as a peak wattage of 3650W. In addition, the device is parallel capable (Firman parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.
With a noise rating of 58 dBA (less noisy than a quiet suburb), the inverter generator features a simple traditional pull-start mechanism.
The W03381 can operate for up to 10 hours with a full tank (fuel consumption around 0.18 GPH), due to its fuel capacity of 1.8 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the W03381 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).
Outlets
The control panel provides the upcoming 3 AC outlets:
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 with which you may charge your batteries with ease.
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The Firman W03381 is an inverter generator and has an encased design of the following dimensions: L23.2 x W17.8 x H17.9 in. Thus, it is more aesthetical than conventional, open frame products. This modern design aims to provide an ideal power solution to recreational users.
As the W03381's weight is only 87 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 W03381's control panel
The control panel of the W03381 includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.
In addition to this info, several light indicators serve to show you when the generator is ready, the generator is overloaded and its oil levels are insufficient.
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.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman W03381 also comes with several accessories, including: oil, funnel, tool kit and battery charging cables.
Emissions
The Firman W03381 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.
Product Video
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 generators of similar power (between 2500 and 3500 W).
- As far as its dry weight is concerned, the Firman W03381 weighs just 87 pounds and thus, it is one of the lighter 2500 to 3500 rated wattage generators. If weight is your top priority, one of the champions in this power category is the Generac GP3300i, weighing just 59.5 pounds.
- Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU3000iS with only 50 dBA.
- Autonomy-wise, with up to 10 hours on a full tank at a 25% load, the W03381 is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides up to 22 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Standing at an estimated 0.18 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you should look out for.
Price comparison
As you can see from this interactive chart, when compared to other 2500-3500W generators, the Firman W03381 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
