- Amateur DIY lovers
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Camping and tailgating hobbyists looking for a portable power source
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Firman W03383 is powered by a 193 cc Firman Max-Pro Series 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. In addition, the device is parallel capable (Firman parallel kit (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added 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 simple and elegant electric starter (battery included). To add further convenience, the W03383 can be remotely started (key fob included).
The fuel capacity of 1.8 gallon allows the W03383 to operate for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).
The W03383 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel features the upcoming 3 AC outlets:
Furthermore, it has 2 DC outlets: there's a 12V 8A receptacle with which you may charge your batteries with ease and a 5V USB port with which you may charge electronics, for example mobile phones or tablets, conveniently.
This Firman generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
The Firman W03383 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.
The W03383 can be taken anywhere with you, thanks to its weight of 91 lbs. 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 W03383's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.
In addition to this info, the light indicators show you if its oil levels are insufficient, the generator is overloaded and the generator is ready.
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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman W03383's package also includes these accessories: battery charging cables, oil, tool kit, funnel, key fob and battery charger.
The Firman W03383 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 therefore, can be used in forested areas.
The Firman W03383 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman W03383 compare to inverter generators of similar power (between 2500 and 3500 W).
- As its weight is 91 pounds, the Firman W03383 falls in the expected weight range of the inverters in the 2500-3500 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
- 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 are concerned with noise, check out the Honda EU3000iS, which is one of the least noisy generators in its power range, with a noise rating of just 50 dBA.
- Regarding its autonomy, the autonomy of the W03383, reaching up to 9 hours at a 25% load, can be considered as low end, compared to other inverters of a roughly equal 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.
- 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. 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 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 W03383 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
