A 193 cc Firman Max-Pro Series OHV 4-stroke engine powers the Firman W03383. It has a 120V output, runs on gas, and has a running wattage of 3,300W and a peak wattage of 3,650W. 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. This inverter generator has a noise rating of 58 dBA, which is lower decibel levels than an average neighbourhood. It can be started with a pull-start mechanism or a simple and elegant electric starter (battery included). The W03383 can be started from afar, which makes it even more convenient (key fob included). With a full tank, the W03383 can run for up to 9 hours on its 1.8-gallon fuel tank (fuel consumption is approximately 0.2 GPH). The W03383 makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 3%, you can safely plug sensitive electronics into its 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 for charging batteries and a 5V USB port for charging devices like cell phones or tablets.The TT-30R plug on this Firman generator is ready for an RV.TT stands for “Travel Trailer”.
The W03383’s control center has a handy meter that you may use to check its status and activity.It displays voltage, frequency, and lifetime hours.In addition to providing this information, the light indicators let you know whether the generator’s oil levels are adequate, whether it is overloaded, and whether it is ready.Because it has an overload protection (circuit breaker) and an automated low oil shut-off, the generator can be utilized with complete security.The Firman W03383 comes with the following accessories in addition to the necessary paperwork and an owner’s manual: battery charging cables, oil, a tool kit, a funnel, a key fob, and a battery charger.
The Firman W03383 is an inverter generator.It has a case that is L23.2 in, x W17.8 in, x H17.9 in, So, it looks better than most other products with open frames.The generator has a modern look and is easy to use when generating power for fun.The W03383 is 91 pounds, which means you can take it anywhere.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-W03383 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 W03383 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).
