Description

Quiet. Portable. Easy to use. The W01785 inverter portable generator is built for fun. Safe for all sensitive electronics. Best used for camping, tailgating and recreational use power supply. (source: Firman (opens in a new tab))

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 especially useful for:

  • Camping and tailgating hobbyists looking for a portable power source
  • Handcrafting enthusiasts who wish to work on-the-go
  • RV travellers who wish to upgrade their experience to another level

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 is powered by a 80 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1700W as well as 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.

Enjoying a noise rating of 54 dBA (just slightly more noisy than a refrigerator), this inverter generator gets running thanks to a simple traditional pull-start mechanism.

With a fuel capacity of 0.9 gallon, the W01785 may run for up to 9 hours with a full tank (fuel consumption around 0.1 GPH).

The W01785 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features the upcoming 2 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 5V USB port (USB-A) allowing you to conveniently charge electronics such as mobile phones and tablets.

Even though this Firman generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor (included).

Portability

Thanks to its closed inverter generator design (L20 x W12.1 x H16.7 in), the Firman W01785, is more esthetical than a typical, open frame generator. The generator has a contemporary design, convenient for recreationally generating power.

Since the W01785 weighs only 45.9 lbs, it can be labeled as a portable lightweight generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed on-the-go. Further convenience is provided by its handle (molded in the case), as it allows you to carry it effortlessly.

Features

Panel of the Firman W01785

The W01785's control panel

Some light indicators allow you to instantly see if the generator is ready, the generator is overloaded and the oil level is too low.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

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).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Firman W01785's package also includes these accessories: funnel, oil, RV adapter and tool kit.

Emissions

The Firman W01785 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable 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 inverter generators of similar power (between 1500 and 2500 W).

  • With a dry weight of 45.9 pounds, the Firman W01785 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.
  • Since the inverter generator's noise is rated at 54 dBA, it has the roughly average expected noise for a device of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU2200i with only 48 dBA.
  • As far as autonomy is concerned, providing up to 9 hours of runtime with a full tank at a 25% load, the W01785 falls into the low end in comparison with other inverters of a comparable power output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the DuroMax XP2300iH, boasting with 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP2300iH, with a fuel consumption of 0.08 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 1500-2500W inverter generators, the Firman W01785 is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
