The Firman P08004 has a 439 cc Firman Max-Pro Series OHV 4-stroke engine that provides 120/240V, runs on gasoline, and puts out 8,000W while running and 10,000W at its peak. This generator has a noise level of 74 dBA, which is just a little louder than a vacuum cleaner. It can be started with a pull-start mechanism or an easy-to-use electric starter (battery included). To make things even easier, the P08004 can be turned on from a distance (key fob included). With a full tank, the P08004 can run for about 12 hours at 0.5 load with an 8-gallon fuel tank (fuel consumption is approximately 0.67 GPH). Since the P08004 has a THD of about 25%, it is best not to use it to power electronics that are sensitive to noise.
The control panel has 5 AC outlets: a 120V 20A (5-20R) duplex outlet, a 120V 30A (L5-30R) outlet, a 120/240V 30A (L14-30R) outlet, and a 120/240V 50A (14-50R) outlet.Since it has a 14-50R outlet, this Firman unit is ready for an RV with a 50-amp service if you have an RV with 50-amp service.With an L5-30P to TT-30R adaptor, its L5-30R plug can also be used to connect a simple RV.The P08004 also has a twist-lock L14-30R receptacle, which makes it ready for a transfer switch.This means that it can power your home when the power goes out, as it can be easily connected to your breaker box.
The P08004’s control panel has a handy meter that shows voltage, frequency, and lifetime hours.This helps you keep track of its status and activity.In addition to this information, a light will show you 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 the machine.For safety, the generator has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worrying.The Firman P08004 comes with the standard paperwork and an owner’s manual, which will help you get the device up and running quickly.It also comes with a key fob, a tool kit, a funnel, and oil.
The Firman P08004 has a standard, open frame that measures L28.4 x W27.9 x H26.8 in, This frame gives it support and lets it be raised off the ground.This type of design is great for tough environments and heavy outdoor use.The generator weighs 210.3 pounds, so it may be hard to move or transport it by hand, even though it is technically considered “portable” (movable).Once it’s on the ground, though, its wheel kit (dia:10 “), and its folding handle can easily fix the problem of limited mobility and make the device easy to move.
The following charts show how some of the most important features of the Firman-P08004 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.
There is a warranty on the Firman P08004 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).
