Zoom on the Firman W03386
In summary, the Firman W03386 is a quiet and compact portable inverter generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Handcrafting enthusiasts who wish to work on-the-go
- Homeowners in need of an emergency backup power for their essentials
- Camping and tailgating buffs looking to enhance their experience
Power & Run Time
The Firman W03386 is powered by a 193 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,300W as well as a peak wattage of 3,650W. Moreover, since it is parallel capable (Firman parallel kit (opens in a new tab) not included), its power may be increased if linked to a second compatible unit.
Enjoying a noise rating of 58 dBA (less noisy than a quiet suburb), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included). The W03386 can also be remotely started, offering further convenience (key fob included).
With a full tank, the W03386 can operate for up to 9 hours (fuel consumption around 0.2 GPH), thanks to its fuel capacity of 1.8 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the W03386 generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).
The control panel features the upcoming 3 AC outlets:
Furthermore, it has 2 DC outlets: there's a 12V 8A receptacle with which charging your batteries is made easy and a 5V USB port (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
The Firman W03386's characteristic encased inverter generator design (L23.2 x W17.8 x H17.9 in), provides an esthetical advantage over any ordinary, open frame product. The design follows the contemporary trends and is perfect for recreationally generating power.
The 91 lbs of the W03386's dry weight enables you to use it anywhere you will ever need. 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.
The W03386 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
In addition to this info, the device’s light indicators will display if the generator is ready, the oil level is too low and the generator is on overload.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
The W03386 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman W03386, the following accessories are also included: key fob, battery charging cables, tool kit, oil, battery charger and funnel.
The Firman W03386 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, making it usable in forested areas.
The Firman W03386 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman W03386 compare to inverter generators of similar power (between 2500 and 3500 W).
- At a weight of 91 pounds, the Firman W03386 places in the expected weight range of the inverter generators in the 2500-3500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Pulsar PGD40iSCO, weighing just 46 pounds.
- As its lowest possible noise is rated at 58 dBA, this inverter generator qualifies as one of the more quiet of the products of similar type and 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.
- The W03386's autonomy is somewhat low end compared to devices of its type and power range, as it reaches only up to 9 hours at 25% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200914, boasting with up to 22 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. In fact, this inverter generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 25% load is around 0.2 GPH. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.
As you can see from this interactive chart, when compared to other 2500-3500W inverter generators, the Firman W03386 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
