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 pounds, the Firman W01781 finds itself in the expected weight range for inverter generators able to produce between 1500 and 2500 rated watts. If you are mindful of weight, the Genmax GM2000i is among the top contenders in this power range, with a dry weight of 34.2 pounds.
- The inverter generator's noise output, rated at 54 dBA, falls within the average range expected for devices in its type and power range. If you'd like a less noisy alternative, the Honda EU2200i is a strong contender. It boasts a noise rating of 48 dBA, placing it among the quietest generators in its power category.
- In terms of its autonomy, the W01781 can operate for up to 9 hours at a 25% load, placing it within the lower bracket among generators of similar type and power range. For those prioritizing autonomy, the DuroMax XP2300iH could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 13 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. Among devices of similar power, this inverter generator has one of the better fuel efficiency, with consumption rates of around 0.1 GPH (gallon per hour) at 25% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen2800c, with a fuel consumption of 0.08 GPH could be in your good books.
Here's a list of the most popular specific comparisons:

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!)
