Zoom on the Firman W03386
In summary, the Firman W03386 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 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's core is the 193 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3300W and 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.
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). For additional convenience, the W03386 may also be remotely started (key fob included).
With a fuel capacity of 1.8 gallon, the W03386 may run for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).
The W03386 produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.
The control panel features the following 3 AC outlets:
Additionally, it features 2 DC outlets: there's a 12V 8A receptacle allowing you to easily charge your batteries and a 5V USB port (USB-A) with which you may charge electronics, for example mobile phones or tablets, conveniently.
This Firman generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').
Since the Firman W03386 is an inverter generator, its closed design (L23.2 x W17.8 x H17.9 in) has an esthetical advantage over conventional, open frame devices. This type of design is the most modern and convenient way to recreationally generate 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's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
In addition to this info, when the oil level is too low, the generator is ready and the generator is overloaded, you will be informed by the featured light indicators.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Firman W03386 also comes with some accessories: battery charging cables, oil, battery charger, key fob, tool kit and funnel are included.
The Firman W03386 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, so it is adequate for use 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).
- Having a dry weight of 91 lbs, the Firman W03386 belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
- 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 9 hours on a full tank at a 25% load, the W03386 is on the low end when compared to other inverter generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.
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.
