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
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's engine, 80 cc Firman Max-Pro Series OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1700W and reaches 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 59 dBA (less noisy than rainfall), the inverter generator features a simple traditional pull-start mechanism.
With a full tank, the W01781 can operate for up to 9 hours (fuel consumption around 0.1 GPH), thanks to its fuel capacity of 0.9 gallon.
Delicate electronics can be plugged in an AC outlets safely, as the W01781 generates a clean sine wave, reaching a <3% Total Harmonic Disruption (THD).
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 with which charging your batteries is made easy.
Since the Firman W01781 is an inverter generator, its closed design (L20 x W12.1 x H16.7 in) has an esthetical advantage over conventional, open frame devices. The generator has a contemporary design, convenient for recreationally generating power.
With a weight of only 45.9 lbs, the W01781 may be viewed as a lightweight and portable generator. The generator can be moved with ease by only one person and so it can 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.
The device’s light indicators will display if the generator is ready, the generator is overloaded and the oil level is too low.
As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off.
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: battery charging cables, tool kit, funnel and oil.
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, which makes it suitable for use 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 generators of similar power (between 1500 and 2500 W).
- Weight-wise, the Firman W01781 has only 45.9 lbs, which renders it one of the lighter generators which produce 1500 to 2500 rated watts. In terms of weight, one of the champions in their power range is the Champion 200949, standing at just 38.6 lbs.
- If compared to generators capable of producing a similar running wattage, this inverter generator with a lowest emitted noise of 59 dBA can be considered somewhat noisy. For those who are looking for a less noisy device, we suggest the Honda EU2200i. With just 48 dBA, it is one of the most quiet devices in this power range.
- 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 products of a roughly equal output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Westinghouse WGen2000, reaching up to 26 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. With an estimated gasoline consumption of 0.1 GPH (gallon per hour) at 25% load, this inverter generator is among the more fuel efficient of the products in the above-mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Predator 2000, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 1500-2500W 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.
