Description

The FIRMAN W01781 Inverter generator features 2100 starting watts and 1700 running watts. Power is supplied by our Max Pro Series 80cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the W01781 running a quiet 54 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The .9 gallon fuel capacity provides a whopping 9 hours of run time. Starting is simple with the FIRMAN First pull, reliable recoil system. (source: Firman (opens in a new tab))

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 in use

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:

Duplex 120V 20A (5-20R)

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

Panel of the Firman W01781

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.

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 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. 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 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.
  • As far as autonomy is concerned, providing up to 9 hours of runtime with a full tank at a 25% load, the W01781 falls into the low end in comparison with other inverters of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the DuroMax XP2300iH, reaching up to 13 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. Among generators of similar power, this inverter generator stands out with a better fuel efficiency than most, with consumption rates around 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.

Price comparison

As you can see from these interactive charts, 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.

    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!)

    + PROS:
    • quiet
    • long running on .9 gallon of gas
    • fairly light weight
    - CONS:
    • Lousy access to check and add oil.
