Description
Zoom on the Firman W03386
In short, the Firman W03386 is a quiet and compact portable inverter generator adequately designed for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- DIYers who wish to improve their efficiency with tools
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.
Power & Run Time
The Firman W03386
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. Furthermore, its parallel capability (Firman parallel kit (opens in a new tab) not included) allows for increasing of power output when connected to another similar or compatible unit, ensuring expanded energy capacity and reliability for various applications.
The inverter generator features a traditional recoil pull-start mechanism and also a convenient and efficient electric starter (battery included). It is rated for a noise of 58 dBA (less noisy than a conversation at home). Additionally, the W03386 may be remotely started, enhancing user convenience (key fob included).
With its 1.8 gallon fuel tank, the W03386 can operate for up to 9 hours when fully fueled (with fuel usage averaging around 0.2 GPH).
As the W03386 produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel features the upcoming 3 AC outlets:
Moreover, it presents 2 DC outlets: there's a 12V 8A receptacle providing easy battery charging capabilities and a 5V USB port (USB-A) ideal for charging various electronic devices such as smartphones and tablets.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Firman generator is RV Ready, making it ideal for powering recreational vehicles.
Portability
The Firman W03386 is an inverter generator and features an encased design with the following dimensions: L23.2 x W17.8 x H17.9 in. This design enhances aesthetics and helps minimize noise levels, distinguishing it from conventional, open frame products. The design follows the contemporary trends and is perfect for recreationally generating power.
At 91 lbs, the W03386 is easily managed, ensuring it can be brought along wherever you need power. Moreover, its set of 2 wheels (⌀5") and its folding handle will allow you to easily shift it once it's on the ground.
Features
The W03386's control panel
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 generator is on overload, its oil levels are insufficient and the generator is ready, you will be informed by the featured light indicators.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
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.
Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Firman W03386 is bundled with additional accessories: battery charger, oil, tool kit, funnel, battery charging cables and key fob.
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. In terms of weight, one of the champions in their power range is the Pulsar PGD40iSCO, standing at just 46 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 you value reduced noise levels, the Honda EU3000iS could be worth considering. It's one of the quietest generators in its power range, rated at 50 dBA.
- As for its runtime, the W03386 runs for up to 9 hours at a 25% load, placing it towards the low end among comparable inverters. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200977, reaching up to 22 hours.
- Run time is a key metric, but it's dependent on the generator's fuel tank capacity. Therefore, discussing fuel efficiency is necessary for a complete understanding. This inverter generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.2 GPH at a 25% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV3500P. With a fuel consumption of as little as 0.13 GPH, it is one of the most efficient generators currently on the market.
Price comparison
As you can see from these interactive charts, 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.
