The Firman W03083 has a gasoline-powered, 171cc Firman Max-Pro Series OHV 4-stroke engine that can put out 120V. It has a running power of 3,000W and a maximum power of 3,300W. Also, the device can work in parallel (but does not come with a Firman parallel kit), so it can be linked to a similar or compatible unit for more power. The noise level of the inverter generator is set at 58 dBA (lower decibel levels than an average neighbourhood). It has both a traditional pull-start mechanism and an electric starter that is convenient and easy to use (battery included). For even more convenience, you can also start the W03083 from a distance (key fob included). With a full tank, the W03083 can run for up to 10 hours because it can hold 1.8 gallons of gas (fuel consumption is approximately 0.18 GPH). The W03083 makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 3%, you can safely plug your sensitive electronics into the AC outlets.
On the control panel, there are 3 AC outlets: a duplex 120V 20A (5-20R) outlet and a 120V 30A (TT-30R) outlet.It also has 2 DC outlets: a 5V USB port for charging devices like phones and tablets, and a 12V 8A receptacle for charging batteries.This Firman generator is ready for an RV because it has a TT-30R (TT stands for “Travel Trailer”) receptacle.
The W03083’s control panel has a handy meter that shows voltage, frequency, and lifetime hours.This helps you keep track of its status and activity.In addition to this, the generator has a number of lights that tell you when it is ready, when it needs more oil, and when it is overloaded.As for safety, the device has an automatic shut-off when it runs out of oil, so you can use it without worry.The Firman W03083 comes with some accessories like battery charging cables, a tool kit, a key fob, a funnel, and oil.It also comes with standard documentation and an owner’s manual to help you get started right away.
Since the Firman W03083 is an inverter generator, its enclosed design (L23.2 x W17.8 x H17.9 in) looks better than a traditional open frame product.This kind of design is the most modern and easy way to make power for fun.With a dry weight of just 90 lbs, the W03083 can go wherever you need power.Also, once it’s on the floor, its two wheels (5 inches in diameter) make it easy to move around “) and its handle that folds up.
The following charts show how some of the most important features of the Firman-W03083 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 W03083 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).
