The Firman W03081 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, since it can work in parallel (but doesn’t come with a Firman parallel kit), its power can be doubled by connecting it to a second unit that works with it. The noise level of the inverter generator is set at 58 dBA (lower decibel levels than rain). It uses a simple, traditional pull-start mechanism to get going. With a full tank, the W03081 can run for up to 10 hours (using about 0.18 GPH of fuel), because it can hold 1.8 gallons of fuel. The W03081 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.Also, it has 2 DC outlets: a 12V 8A receptacle that makes it easy to charge batteries and a 5V USB port that makes it easy to charge devices like cell phones and tablets.This Firman generator is ready for an RV because it has a TT-30R (TT stands for “Travel Trailer”) receptacle.
The W03081 and its control panel have a handy meter that shows voltage, frequency, and the number of hours the battery will last.This makes it easier to keep track of its status and activity.In addition to this information, there are several lights that tell you when the generator is ready, when it is overloaded, and when it needs more oil.As for safety features, the device has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without worry.The Firman W03081 comes with a tool kit, oil, battery charging cables, and a funnel, as well as the usual paperwork and an owner’s manual to get you up and running quickly.
The encased inverter generator design of the Firman W03081 (L23.2 x W17.8 x H17.9 in) makes it look better than any ordinary open frame product.This kind of design is the most modern and easy way to make power for fun.With a dry weight of 84 lbs, the W03081’s power can be used anywhere.Also, it has a set of two wheels with a 5 “Once it’s on the floor, it’s easy to move because of the wheels and the handle that folds up.

- 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 W03081 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).
