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 buffs looking to enhance their experience
  • Handcrafting enthusiasts who wish to work on-the-go
  • RV travellers who wish to upgrade their experience to another level

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

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 1,700W as well as a peak wattage of 2,100W. In addition, the device is parallel capable (parallel kit not included) and thus, can be linked to a similar or compatible unit for added power.

At a noise rating of 54 dBA (just slightly more noisy than a conversation at home), the inverter generator is started via a simple traditional pull-start mechanism.

The W01785's fuel tank holds 0.9 gallon, ensuring uninterrupted operation for up to 9 hours with a full tank (fuel consumption approximately 0.1 GPH).

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

Outlets

The control panel provides the upcoming 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) ideal for charging various electronic devices such as smartphones and tablets.

Though it may not be labeled as 'RV Ready,' this Firman generator offers the benefit of hassle-free RV connectivity through its L5-30R receptacle, allowing you to easily power your RV with the assistance of an L5-30P to TT-30R adaptor (included).

Portability

With its enclosed inverter generator design (L20 x W12.1 x H16.7 in), the Firman W01785 offers superior aesthetics and operates with minimized noise levels, distinguishing itself from standard, open frame generators. The featured design follows the latest trends and is ideal for easy and recreational use.

The W01785's weight, at just 45.9 lbs, makes it an ideal choice for those seeking a lightweight and portable generator. As it can be moved by a single person without much effort, the generator and its power can be enjoyed on-the-go. The inclusion of a handle (molded in the case) makes carrying it a breeze, adding to its convenience.

Features

The W01785's control panel

The light indicators show you if the generator is ready, the generator is on overload and its oil levels are insufficient.

In terms of security, the generator features an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during its use.

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.

Alongside the standard documentation and an owner's manual (opens in a new tab) for quick setup, the Firman W01785 is bundled with additional accessories: tool kit, oil, RV adapter and funnel.

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).

  • Having a dry weight of 45.9 lbs, the Firman W01785 belongs in the expected weight range for inverter generators which produce 1500 to 2500 rated watts. If weight is a key factor for your needs, the Genmax GM2000i is noteworthy for being one of the top contenders in this power range, with a dry weight of 34.2 pounds.
  • Because this inverter generator emits noise as low as 54 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you value reduced noise levels, the Honda EU2200i could be worth considering. It's one of the quietest generators in its power range, rated at 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 prolonged run time is essential to your needs, you could consider the DuroMax XP2300iH, which offers one of the highest autonomy among devices with similar power output, lasting up to 13 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. 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 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.
According to our stats, the following comparison is pretty popular: Firman W01785 vs Firman W01781.

Price comparison

As you can see from these interactive charts, 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.
