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
- Amateur DIY lovers
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
The Firman W01781
The Firman W01781 is powered by a 80 cc Firman Max-Pro Series OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1,700W as well as a peak wattage of 2,100W. Moreover, the parallel capability (Firman parallel kit (opens in a new tab) not included) allows for doubling of power output when paired with another similar or compatible unit, providing increased energy capacity and reliability for diverse needs.
Operating with a noise level of 54 dBA (just slightly more noisy than a refrigerator), the inverter generator starts up via a simple traditional pull-start mechanism.
The W01781 can operate for up to 9 hours with a full tank (fuel consumption around 0.1 GPH), due to its fuel capacity of 0.9 gallon.
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 upcoming 2 AC outlets:
Furthermore, it has 2 DC outlets: there's a 5V USB port designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage and a 12V 5A (cigarette lighter style) receptacle allowing you to easily charge your batteries.
Portability
Since the Firman W01781 is an inverter generator, its closed design (L20 x W12.1 x H16.7 in) not only provides an aesthetic advantage but also contributes to reduced noise levels compared to conventional, open frame devices. This type of design is the most modern and convenient way to recreationally generate power.
With a weight of only 45.9 lbs, the W01781 is deisgned to be a lightweight and easily portable generator. Moving it around should pose no challenge for a single person, allowing for power availability wherever you go. With its handle (molded in the case), carrying it becomes a breeze, adding to its convenience.
Features
The W01781's control panel
The device's light indicators will illuminate to indicate if the generator is ready, its oil levels are insufficient and the generator is on overload.
Considering security aspects, the generator boasts an automatic low oil shut-off, offering peace of mind throughout operation.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman W01781's package also includes these accessories: tool kit, battery charging cables, oil and funnel.

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).
- With a dry weight of 45.9 lbs, the Firman W01781 falls within the expected weight range for inverter generators in the 1500 to 2500 rated wattage. Regarding dry weight, one of the champions in the same power range is the Genmax GM2000i, with a dry weight of only 34.2 lbs.
- As this inverter generator can emit noise as low as 54 dBA, it finds itself in the average expected noise for this kind of power. 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.
- Concerning its runtime, the W01781 provides up to 9 hours at a 25% load, indicating that it falls on the lower side compared to other generators of its type and power range. If prolonged run time is essential to your needs, you could consider the DuroMax XP2300iH, which offers one of the highest autonomy among devices with similar power output, lasting up to 13 hours.
- Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. At an estimated fuel consumption of 0.1 GPH (gallon per hour) at 25% load, this inverter generator is a rather fuel-efficient one within its wattage category. If you're placing a high priority on fuel consumption, the Westinghouse iGen2800, with a low fuel consumption rate of 0.08 GPH, could be an option to consider.
Here's a list of the most popular specific comparisons:
Price comparison
As you can see from these interactive charts, when compared to other 1500-2500W inverter 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.

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!)
