Description
Zoom on the Firman W03381
In a nutshell, the Firman W03381 is a quiet and compact portable inverter generator mostly geared towards:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating hobbyists looking for a portable power source
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.
Power & Run Time
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 quiet suburb), the inverter generator features a simple traditional pull-start mechanism.
With a fuel capacity of 1.8 gallon, the W03381 may run for up to 10 hours with a full tank (fuel consumption around 0.18 GPH).
The W03381 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel features the upcoming 3 AC outlets:
In addition, it provides 2 DC outlets: there's a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient and a 12V 8A receptacle with which you may charge your batteries with ease.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready.
Portability
Thanks to its closed inverter generator design (L23.2 x W17.8 x H17.9 in), the Firman W03381, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.
The W03381's dry weight of 87 lbs lets you use its power anywhere needed. Moreover, once it’s on the ground, its wheel kit (⌀5") and its folding handle will allow you to shift it without effort.
Features
To help you monitor the W03381's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.
In addition to this info, several light indicators serve to show you when the generator is overloaded, the oil level is too low and the generator is ready.
As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman W03381's package also includes these accessories: battery charging cables, funnel, oil and tool kit.
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).
- In terms of its dry weight, the Firman W03381 stands at only 87 lbs, meaning that is one of the lighter devices of the 2500-3500 rated wattage category Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- With a lowest possible noise of 58 dBA, this inverter generator places itself amongst the more quiet of the products delivering similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU3000iS, whose lowest noise levels reach just 50 dBA.
- As far as autonomy is concerned, providing up to 10 hours of runtime with a full tank at a 25% load, the W03381 falls into the low end in comparison with other devices of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200954, reaching 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. This inverter generator has an estimated fuel consumption of roughly 0.18 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3200P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.
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.
