A 171 cc Firman Max-Pro Series OHV 4-stroke engine powers the Firman W02981. It has a 120V output, runs on gas, and has a running wattage of 2,900W and a peak wattage of 3,200W. Also, the generator can be connected to a second unit to make more power (a Firman parallel kit is not included). This inverter generator has a noise level of 58 dBA, which is quieter than rain. It starts up with a traditional pull-start mechanism. Because it can hold 1.8 gallons of fuel, the W02981 can run for up to 10 hours on a full tank (it uses about 0.18 GPH). The W02981 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 12V 8A receptacle for charging batteries and a 5V USB port for charging devices like cell phones and tablets.The TT-30R plug on this Firman generator is ready for an RV.TT stands for “Travel Trailer”.
The status and activity of the W02981 can be easily checked on the control panel, which has a meter that shows voltage, frequency, and lifetime hours.In addition to this, the generator has a number of lights that tell you when the oil level is too low, when the generator is ready, and when it is overloaded.In terms of safety, the generator can be used without worry because it has a circuit breaker for overheating and an automatic shut-off when the oil level gets too low.The Firman W02981 comes with the standard paperwork and an owner’s manual, which will help you get the device up and running quickly.Also included are battery charging cables, a tool kit, oil, and a funnel.
The Firman W02981 is an inverter generator with the following dimensions: L23.2 x W17.8 x H17.9 in, So, it looks better than most other products with open frames.This kind of design is the most modern and easy way to make power for fun.The W02981’s dry weight of 84 pounds lets you take it anywhere you need to.It can also be moved easily thanks to its set of two wheels (dia:5 “) and its handle that folds up, once it’s on the ground.
The following charts show how some of the most important features of the Firman-W02981 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 W02981 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).
