  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

Power & Run Time

The Firman W01784 in use

The Firman W01784

The Firman W01784 houses a 80 cc Firman Max-Pro Series OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1700W along with a peak wattage of 2100W. Additionally, as the generator is parallel capable (parallel kit not included), it can be linked to a second unit for more power.

The inverter generator is rated for a noise of 54 dBA (just slightly more noisy than a conversation at home). Its starting mechanism is based on a simple traditional pull-start mechanism.

Thanks to a fuel capacity of 0.9 gallon, the W01784 can operate for up to 9 hours with a full tank (fuel consumption around 0.1 GPH).

As the W01784 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

Outlets

The control panel features the upcoming 2 AC outlets:

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

It also sports 1 DC outlet: there's a 5V USB port with which charging of electronics like mobile phones and tablets is made convenient.

While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor (included).

Portability

The Firman W01784 is an inverter generator and has an encased design of the following dimensions: L20 x W12.1 x H16.7 in. Thus, it is more aesthetical than conventional, open frame products. The design follows the contemporary trends and is perfect for recreationally generating power.

With a weight of only 45.9 lbs, the W01784 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. It can also be carried without effort with a featured handle (molded in the case), further improving its convenience.

Features

The W01784's control panel

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

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

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman W01784 also is packed along with the following accessories: oil, battery charging cables, tool kit, RV adapter and funnel.

Emissions

The Firman W01784 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, which makes it suitable for use in forested areas.

The Firman W01784 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman W01784 compare to generators of similar power (between 1500 and 2500 W).

  • Regarding its weight, the Firman W01784 only weighs in at 45.9 pounds, which means it's one of the lighter generators in the 1500-2500 rated wattage range. 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 power. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
  • As for its autonomy, the W01784, with an autonomy of up to 9 hours at a 25% load, is placed on the low end among the generators of its kind. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption 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 Energizer eZV2200P, which has a fuel consumption of only 0.08 GPH and thus, is one of the most efficient devices in our database.
According to our stats, the following comparison is pretty popular: Firman W01784 vs Firman W01781.

How do you reset circuit breaker when it trips off (Asked October 25, 2020)

The circuit breaker/reset button is located above the L5-30R outlet.

Is the 30Amp receptacle only functional if there are 2 units in parallel? Can a single unit provide 30 Amps? (Asked December 19, 2020)

The L5-30R receptacle is functional without paralleling anything. However, you will only get a maximum of 14.2 running amps or 17.5 starting amps out of it.
