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 hobbyists looking for a portable power source
- 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 1,700W along with a peak wattage of 2,100W. Additionally, as the generator is parallel capable (Firman parallel kit (opens in a new tab) not included), it can be linked to a second unit for more power.
With a noise rating of 54 dBA (just slightly more noisy than a refrigerator), 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).
The W01781 produces a clean sine wave: thanks to a <3% Total Harmonic Distortion (THD), your sensitive electronics can be safely plugged in the AC outlets.
Outlets
The control panel features the following 2 AC outlets:
In addition, it provides 2 DC outlets: there's a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient and a 12V 5A (cigarette lighter style) receptacle allowing you to easily charge your batteries.
Portability
As the Firman W01781 is an inverter generator, its encased design (L20 x W12.1 x H16.7 in) offers more aesthetics than a conventional, open frame product. The featured design follows the latest trends and is ideal for easy and recreational use.
Since the W01781 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. In addition, a handle (molded in the case) lets you carry it easily and further increases its convenience.
Features
The W01781's control panel
Some light indicators allow you to instantly see if its oil levels are insufficient, the generator is ready and the generator is on overload.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman W01781 also is packed along with the following accessories: oil, battery charging cables, tool kit and funnel.
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 and thus, may be used 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 is your top priority, one of the champions in this power category is the Genmax GM2000i, weighing just 34.2 pounds.
- This inverter generator has a somewhat average expected noise for its type and power range, rated at 54 dBA. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 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. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the DuroMax XP2300iH, which is able to run for 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 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 fuel consumption is your top priority, we suggest to check out the DuroMax XP2300iH, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
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 cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

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!)
