Zoom on the Firman W03381
In summary, the Firman W03381 is a quiet and compact portable inverter generator especially useful for:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
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's design includes a gasoline-fueled 193 cc Firman Max-Pro Series OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3300W and also a peak wattage of 3650W. Additionally, as the generator is parallel capable (Firman parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
With a noise rating of 58 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 W03381 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 W03381 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).
Outlets
The control panel provides the upcoming 3 AC outlets:
Additionally, it features 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.
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Firman generator is RV Ready.
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. The generator has a contemporary design, convenient for recreationally generating power.
As the W03381's weight is only 87 lbs, it can follow you and your power needs anywhere. In addition, with its wheel kit (⌀5") and its folding handle, it may be shifted with ease, once placed the floor.
Features
The W03381's control panel
To help you monitor the W03381's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
In addition to this info, several light indicators serve to show you when the oil level is too low, the generator is ready and the generator is on overload.
Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.
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.
Emissions
The Firman W03381 is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.
Moreover, it features a spark arrestor and thus, may be used 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).
- Regarding its weight, the Firman W03381 only weighs in at 87 pounds, which means it's one of the lighter generators in the 2500-3500 rated wattage range. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 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 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.
- Autonomy-wise, with up to 9 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 Honda EU3000iS, as it provides up to 20 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. As this inverter generator uses an estimated 0.2 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3200P, with a fuel consumption of 0.13 GPH could be in your good books.
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.
