The core of the Firman W01784 is a gasoline-powered 80 cc Firman Max-Pro Series OHV 4-stroke engine. It has a 120V output and a running power of 1,700W and a peak power of 2,100W. Also, since it can work in parallel (but doesn’t come with a parallel kit), this power can be doubled by connecting it to another unit that works with it. This inverter generator has a noise level of 54 dBA, which is just a little louder than a conversation at home. It starts up with a traditional pull-start mechanism. With a full tank, the W01784 can run for up to 9 hours on its 0.9-gallon fuel tank (fuel consumption is approximately 0.1 GPH). The W01784 makes a clean sine wave with a Total Harmonic Distortion of 3%, so you can safely plug in sensitive electronics (THD).
The control panel has two AC outlets: one for 120V 20A (5-20R) and one for 120V 30A (L5-30R).It also has 1 DC outlet and a 5V USB port for charging devices like phones and tablets.Even though this Firman generator isn’t quite RV Ready, its L5-30R receptacle makes it easy to connect to an RV with an L5-30P to TT-30R adaptor (which comes with the generator).
There are several lights that let you know when the generator is ready, when the oil level is too low, and when the generator is too busy.As far as safety goes, the device has an automatic shut-off for low oil and a circuit breaker for overheating, so you can use it without worrying.The Firman W01784 comes with the usual paperwork and an owner’s manual , which lets you start it right away.It also comes with battery charging cables, a tool kit, a funnel, an RV adapter, and oil.
The Firman W01784 is an inverter generator, and its closed design (L20 x W12.1 x H16.7 in) makes it look better than traditional devices with open frames.The goal of this modern design is to give recreational users the best way to get power.The W01784 is called a lightweight portable generator, and it only weighs 45.9 pounds.The generator is easy for one person to move, so it can be used anywhere.The handle built into the case makes it even easier to carry.
The following charts show how some of the most important features of the Firman-W01784 compare to other generators with the same power output.

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
About the Manufacturer
Firman Power Equipment is a business with a recent but reputable history in the power equipment sector.It was founded in 1999.The Arizona-based business provides a vast array of goods, including power tools, automotive equipment, storage items, work clothing, but its assortment of generators of different shapes, sizes, and outputs stands out above the rest.Interestingly, Firman serves as a de facto distributor of China National Machinery Industry Corporation’s goods in the US and is a fully owned subsidiary of that business.
A warranty covers the Firman W01784 for up to 3 years.This warranty may not cover all parts of the generator or may only cover certain parts.Check out Firman’s warranty policies if you want to know more about the warranty on a Firman generator.You can also call their customer service line at 1-844-FIRMAN1 (844-347-6261).
