Zoom on the Firman W01785

The Firman W01785 is the newer version of the W01784. It's a quiet, compact and lightweight portable inverter generator mostly geared towards:

  • Camping and tailgating buffs looking to enhance their experience
  • Amateur DIY lovers
  • RV travellers looking for even more independence

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman W01785 houses a 80 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1700W along with a peak wattage of 2100W. In addition, as it is parallel capable (parallel kit not included), this power can be doubled when linked to another similar or compatible unit.

With a noise rating of 54 dBA (just slightly more noisy than a refrigerator), the inverter generator features a conventional pull-start mechanism.

With a full tank, the W01785 can operate for up to 9 hours (fuel consumption around 0.1 GPH), thanks to its fuel capacity of 0.9 gallon.

The W01785 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the following 2 AC outlets:

120V 20A (5-20R) receptacle
120V 30A (L5-30R) receptacle

Furthermore, it has 1 DC outlet: there's a 5V USB port (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.

This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor (included). However, it is still not quite RV ready.

Portability

As the Firman W01785 is an inverter generator, its encased design (L20 x W12.1 x H16.7 in) offers more aesthetics than a conventional, open frame product. This type of design is the most modern and convenient way to recreationally generate power.

With a weight of only 45.9 lbs, the W01785 may be viewed as a lightweight and portable generator. The product’s power can be enjoyed on-the-go, as it can be moved by a single person without trouble. Its handle (molded in the case) allows you to carry it easily, further enhancing its convenience.

Features

Panel of the Firman W01785

The W01785's control panel

The device’s light indicators will display if its oil levels are insufficient, the generator is ready and the generator is on overload.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

The W01785 also benefits from Firman’s CO Alert carbon monoxide shutdown, which automatically shuts down the engine when harmful levels of carbon monoxide accumulate around the generator or a CO Alert fault occurs. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Firman W01785, the following accessories are also included: RV adapter, funnel, tool kit and oil.

Emissions

The Firman W01785 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, so it is adequate for use in forested areas.

The Firman W01785 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W01785 compare to generators of similar power (between 1500 and 2500 W).

  • Regarding its weight, the Firman W01785 only weighs in at 45.9 pounds, which means it's one of the lighter generators in the 1500-2500 rated wattage range. In terms of weight, one of the champions in their power range is the Genmax GM2000i, standing at just 34.2 lbs.
  • Since the inverter generator's noise is rated at 54 dBA, it has the roughly average expected noise for a device of similar power. 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.
  • The W01785's autonomy is somewhat low end compared to devices of its power range, as it reaches only up to 9 hours at 25% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Yamaha EF2800i, boasting with up to 14.7 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV2200P. With a fuel consumption of as little as 0.08 GPH, it is one of the most efficient generators currently on the market.
