The gasoline-powered 193 cc OHV 4-stroke engine is the heart of the Firman W03386. It has a 120V output and a running power of 3,300W and a peak power of 3,650W. Also, since it can work in parallel (but doesn’t come with a Firman parallel kit), this power can be increased by connecting it to another unit that works with it. This inverter generator makes 58 dBA of noise, which is less than a refrigerator. It can be started with a pull-start mechanism or an easy-to-use electric starter (battery included). The W03386 can also be started from a distance, which makes it even more convenient (key fob included). With a 1.8-gallon fuel tank, the W03386 can go for up to 9 hours on a full tank (fuel consumption is approximately 0.2 GPH). The W03386 makes a clean sine wave. Its Total Harmonic Distortion (THD) is less than 3%, so you can safely plug sensitive electronics into its AC 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.It also has 2 DC outlets: a 12V 8A receptacle that makes it easy to charge your batteries and a 5V USB port (USB-A) that makes it easy to charge electronics like cell phones or tablets.The TT-30R plug on this Firman generator is ready for an RV.TT stands for “Travel Trailer”.
There is a handy meter included into the W03386 and its control panel that shows voltage, frequency, and lifetime hours.When keeping an eye on its status and activity, this function is helpful.In addition to providing you with this information, the light indications let you know whether the oil level is too low, the generator is overloading, or it is ready.The generator may be used without worrying about security because it has an automated low oil shut-off and an overload safeguard (circuit breaker).The Firman CO Alert carbon monoxide shutdown, which automatically shuts down the engine when dangerous amounts of carbon monoxide build up around the generator or a CO Alert malfunction occurs, is another advantage for the W03386.Though it’s a wonderful extra measure of security, make sure to carry your generator outside at all times.The Firman W03386 comes with the following extras in addition to the standard paperwork and an owner’s manual , which enables you to use it straight away: a key fob, funnel, oil, tool kit, battery charging cables, and charger.
The encased inverter generator design of the Firman W03386 (L23.2 x W17.8 x H17.9 in) makes it look better than any ordinary open frame product.The design fits with what’s popular now and is perfect for generating power for fun.With a dry weight of just 91 lbs, the W03386 can go wherever you need power.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 W03386 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).
