Zoom on the Firman W01781
In summary, the Firman W01781 is a quiet, compact and lightweight portable inverter generator especially useful for:
- Camping and tailgating hobbyists looking for a portable power source
- Handcrafting enthusiasts who wish to work on-the-go
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 W01781
The Firman W01781 houses a 80 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1700W along with a peak wattage of 2100W. In addition, the device is parallel capable (Firman parallel kit not included) and thus, can be linked to a similar or compatible unit for added power.
The inverter generator features a simple traditional pull-start mechanism. It is rated for a noise of 59 dBA (less noisy than rainfall).
With a full tank, the W01781 can operate for up to 9 hours (fuel consumption around 0.1 GPH), thanks to its fuel capacity of 0.9 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the W01781 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).
Outlets
The control panel provides the upcoming 2 AC outlets:
It also sports 2 DC outlets: there's a 5V USB port allowing you to conveniently charge electronics such as mobile phones and tablets and a 12V 5A (cigarette lighter style) receptacle with which charging your batteries is made easy.
Portability
The Firman W01781's characteristic encased inverter generator design (L20 x W12.1 x H16.7 in), provides an esthetical advantage over any ordinary, open frame product. The generator has a contemporary design, convenient for recreationally generating power.
Labeled a lightweight portable generator, the W01781 weighs just 45.9 lbs. A single person should not have any problems moving it around and thus, enjoy power availability on-the-go. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
Features
The W01781's control panel
The light indicators show you if its oil levels are insufficient, the generator is ready and the generator is overloaded.
From a security point of view, the generator is equipped with an automatic low oil shut-off, giving you a peace of mind during use.
Besides the classic documentation and a user manual to get you promptly started, the Firman W01781 also comes with some accessories: battery charging cables, tool kit, funnel and oil are included.
Emissions
The Firman W01781 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, which makes it suitable for use in forested areas.
Product Video
The Firman W01781 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Firman W01781 compare to generators of similar power (between 1500 and 2500 W).
- In terms of its dry weigh, the Firman W01781 stands at only 45.9 lbs, meaning that is one of the one of the lighter devices of the 1500-2500 rated wattage category If you are concerned by weight, one of the champions in the above mentioned power range is the WEN 56202i, with a dry weight of just 38.6 pounds.
- This inverter generator, with its lowest possible noise rated at 59 dBA falls into the more noisy category, compared to other devise of a similar running wattage. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
- Autonomy-wise, with up to 9 hours on a full tank at a 25% load, the W01781 is on the low end when compared to other 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 Westinghouse WGen2000, reaching up to 26 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.1 GPH (gallon per hour) at 25% load. 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.
Price comparison
As you can see from this dynamic chart, when compared to other 1500-2500W generators, the Firman W01781 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
