Description
The Firman P03608 is made with a 208 cc Firman Max-Pro Series OHV 4-stroke engine that runs on gasoline. It has a 120V output and a running power of 3,650W and a peak power of 4,550W. The generator is meant to make 67 dBA of noise (quieter than a regular conversation). It has both a simple pull-start mechanism and an electric starter that is easy to use and convenient (battery included). The P03608 can also be started from a distance, which makes it even more convenient (key fob included). With a full tank, the P03608 can run for about 14 hours at 0.5 load (its fuel consumption is about 0.36 GPH). This is because it has a 5 gallon fuel capacity. Since the P03608 has a THD of about 25%, it is best not to use it to power electronics that are sensitive to noise.
Outlets
On the control panel, there are 4 AC outlets for: Duplex 120V 20A (5-20R); 120V 30A (TT-30R) receptacle; 120V 30A (L5-30R) receptacle.
The TT-30R plug on this Firman generator is ready for an RV.TT stands for “Travel Trailer”.Features
The P03608’s control panel has a handy meter that shows voltage, frequency, and lifetime hours.
This makes it easy to keep track of its status and activity.In addition to this, the featured light indicator will let you know when the oil level is too low.The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in it.From a safety point of view, the product has an automatic shut-off for low oil and an overload protection (circuit breaker), so you can use it without worrying.The Firman P03608 comes with the usual paperwork and an owner’s manual , which lets you start it right away.It also comes with a tool kit, oil, a funnel, and a key fob.Mobility
The Firman P03608 is a standard, open-frame generator with dimensions of L24.8 x W21.7 x H21.7 in, This gives the generator stability and lets it be raised above ground level.
The design shown is great for the outdoors and other rough places.Even though this device is technically portable (meaning it can be moved), it can be hard to move and use without special tools because it weighs 119.5 pounds.Once it is on the ground, it can still be moved easily with the help of its wheel kit (diameter: 8″) and its folding handle.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.
