It’s ergonomic encasing and lightweight design makes it easy to transport for those weekend camping getaways. This generator features 2100 starting watts and 1700 running watts and a neutral bonded to frame, perfect for boating with a reliable recoil start system. (source: Firman (opens in a new tab))

Zoom on the Firman W01783

In summary, the Firman W01783 is a quiet, compact and lightweight portable inverter generator especially useful for:

  • Camping and tailgating buffs looking to enhance their experience
  • Amateur DIY lovers

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Firman W01783's core is the 80 cc Firman Max-Pro Series OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 1700W and a peak wattage of 2100W.

At a noise rating of 59 dBA (less noisy than a refrigerator), the inverter generator is started via a simple traditional pull-start mechanism.

The fuel capacity of 0.9 gallon allows the W01783 to operate for up to 9 hours with a full tank (fuel consumption around 0.1 GPH).

The W01783 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

In addition, it provides 2 DC outlets: there's a 12V 5A (cigarette lighter style) receptacle allowing you to easily charge your batteries and a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

Portability

Since the Firman W01783 is an inverter generator, its closed design (L20 x W12.1 x H16.7 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.

Since the W01783 weighs only 45.9 lbs, it can be labeled as a portable lightweight generator. The generator can be moved with ease by only one person and so it can be enjoyed on-the-go. This convenience is further enhanced thanks to its handle (molded in the case) that allows you to carry it with ease.

Features

Panel of the Firman W01783

The W01783's control panel

Several light indicators serve to show you when the generator is on overload, the generator is ready and the oil level is too low.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Along the basic documentation and an owner's manual, useful for starting the generator right away, the Firman W01783's package also includes these accessories: oil, funnel, tool kit and battery charging cables.

Emissions

The Firman W01783 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, which makes it suitable for use in forested areas.

The Firman W01783 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W01783 compare to generators of similar power (between 1500 and 2500 W).

  • Regarding its weight, the Firman W01783 only weighs in at 45.9 pounds, which means it's one of the lighter generators in the 1500-2500 rated wattage range. In terms of weight, one of the champions in their power range is the Champion 200949, standing at just 38.6 lbs.
  • When compared to devices able to produce a similar running wattage, this inverter generator and its lowest emitted noise of 59 dBA is on the noisier side. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
  • As for its autonomy, the W01783, with an autonomy of up to 9 hours at a 25% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen2000, which is able to run for up to 26 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This inverter generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.1 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Predator 2000, which boasts with a gas consumption of only 0.08 GPH, may be the right generator for you.
