Description
A 193 cc Firman Max-Pro Series OHV 4-stroke engine powers the Firman W03381. 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. The inverter generator makes 58 dBA of noise, which is less than a refrigerator. It has a simple pull-start mechanism. Because it can hold 1.8 gallons of fuel, the W03381 can run for up to 10 hours on a full tank (it uses about 0.18 GPH). As the W03381 makes a clean sine wave with a Total Harmonic Distortion (THD) of less than 3%, you can safely plug sensitive electronics into the AC outlets.
Outlets
The control panel has 3 AC outlets: a duplex 120V 20A (5-20R) outlet, a 120V 30A (TT-30R) outlet, and a 120V 20A (TT-20R) outlet.
Also, it has 2 DC outlets: a 5V USB port that makes it easy to charge devices like cell phones and tablets, and a 12V 8A receptacle that makes it easy to charge batteries.This Firman generator is ready for an RV because it has a TT-30R plug (TT stands for “Travel Trailer”).Features
There is a handy meter on the W03381’s control panel that displays voltage, frequency, and lifetime hours.
When keeping an eye on its status and activity, this function is helpful.Along with this information, a number of light indications let you know whether the generator is ready, the oil level is too low, or it is overloading.The automatic low oil shut-off and overload protection (circuit breaker) on the generator provide you with security and peace of mind when using it.The Firman W03381 also includes several supplies, such as oil, a funnel, battery charging connections, and a tool kit, in addition to the standard documentation and an owner’s manual to get you started right away.Mobility
The encased inverter generator design of the Firman W03381 (L23.2 x W17.8 x H17.9 in) makes it look better than any ordinary open frame product.
The goal of this modern design is to give recreational users the best way to get power.With a dry weight of 87 lbs, the W03381’s power can be used anywhere.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.Product Videos

- 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.
