Description
Zoom on the Firman W01781
In a nutshell, the Firman W01781 is a quiet, compact and lightweight portable inverter generator mostly geared towards:
- Camping and tailgating buffs looking to enhance their experience
- Handcrafting enthusiasts who wish to work on-the-go
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 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. Moreover, since it is parallel capable (Firman parallel kit (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.
With a noise rating of 54 dBA (just slightly more noisy than rainfall), the inverter generator features a conventional pull-start mechanism.
Thanks to a fuel capacity of 0.9 gallon, the W01781 can operate for up to 9 hours with a full tank (fuel consumption around 0.1 GPH).
As the W01781 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel includes the following 2 AC outlets:
Additionally, it features 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 allowing you to easily charge your batteries.
Portability
The Firman W01781 is an inverter generator and has an encased design of the following dimensions: L20 x W12.1 x H16.7 in. Thus, it is more aesthetical than conventional, open frame products. The design follows the contemporary trends and is perfect for recreationally generating power.
Labeled a lightweight portable generator, the W01781 weighs just 45.9 lbs. The device can be easily moved by just one person and thus, its power may 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
The W01781's control panel
When its oil levels are insufficient, the generator is ready and the generator is on overload, you will be informed by the featured light indicators.
As for its security measures, the device features an automatic low oil shut-off, letting you use it with a peace of mind.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman W01781 also comes with several accessories, including: battery charging cables, oil, tool kit and funnel.
Emissions
The Firman W01781 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, making it usable in forested areas.

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 inverter generators of similar power (between 1500 and 2500 W).
- As its weight is 45.9 pounds, the Firman W01781 falls in the expected weight range of the inverters in the 1500-2500 rated wattage category. If weight matters to you, one of the champions in this power range is the Genmax GM2000i with only 34.2 pounds.
- The inverter generator can be considered average in its noise for its type and power category, as it is rated at 54 dBA. If noise emissions are one of your priorities, you may be interested in the Honda EU2200i, one of the least noisy generators similarly powerful as this one, rated for 48 dBA.
- Regarding its autonomy, the autonomy of the W01781, 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 you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the DuroMax XP2300iH, with up to 13 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the DuroMax XP2300iH is a device you could look out for.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from this interactive chart, when compared to other 1500-2500W inverter generators, the Firman W01781 is on the average side of the price range.

User Reviews
not too heavy at approx 48 lb.
quiet – sitting just outside the mobile home and we can’t hear it inside.
ran all night on a tank of fuel which is .9 gal.
In order to check the oil; the front panel must be removed. There are several tiny screws to undo and possibly in the dark. Very terrible design feature. Other than that I would recommend this generator. (I’m going to cut an access hole!)
