Power & Run Time

The Firman W03383 in use

The Firman W03383

The Firman W03383's engine, 193 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3300W and reaches a peak wattage of 3650W. Additionally, as the generator is parallel capable (Firman parallel kit not included), it can be linked to a second unit for more power.

The inverter generator is rated for a noise of 58 dBA (less noisy than a refrigerator). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). For additional convenience, the W03383 may also be remotely started (key fob included).

With a fuel capacity of 1.8 gallon, the W03383 may run for up to 9 hours with a full tank (fuel consumption around 0.2 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the W03383 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's a 12V 8A receptacle allowing you to easily charge your batteries 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').

Portability

As the Firman W03383 is an inverter generator, its encased design (L23.2 x W17.8 x H17.9 in) offers more aesthetics than a conventional, open frame product. This modern design aims to provide an ideal power solution to recreational users.

As the W03383's weight is only 93 lbs, it can follow you and your power needs anywhere. In addition, with a wheel kit (⌀5") and a folding handle, it may be displaced with ease, once placed the floor.

Features

Panel of the Firman W03383

The W03383's control panel

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 the generator is on overload, its oil levels are insufficient and the generator is ready.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

Along the basic documentation and a user manual, useful for starting the generator right away, the Firman W03383's package also includes these accessories: battery charging cables, battery charger, key fob, tool kit, funnel and oil.

Emissions

The Firman W03383 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, making it usable 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 generators of similar power (between 2500 and 3500 W).

  • Weight-wise, the Firman W03383 has only 93 lbs, which renders it one of the lighter generators which produce 2500 to 3500 rated watts. 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.
  • 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 one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
  • Autonomy-wise, with up to 9 hours on a full tank at a 25% load, the W03383 is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EU3000iS, as it provides up to 20 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 has an estimated fuel consumption of roughly 0.2 GPH (gallon per hour) at a 25% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Energizer eZV3200P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this dynamic chart, when compared to other 2500-3500W 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.
