The Firman H08053 is powerful and versatile because it runs on both 120V and 240V. This is made possible by its dual-fuel technology. When it is running on gasoline, it has a running wattage of 8,000W and a peak wattage of 10,000W. When run by propane, it has a rated power of 7250 watts and a peak power of 9050 watts. The generator has both a simple and elegant pull-start mechanism and an electric starter (battery included). It has a noise level of 74 dBA (A tad noisier than a vacuum cleaner). The H08053, which can hold 8 gallons of gas, can run for about 12 hours at 0.5 load with a full tank (fuel consumption is approximately 0.67 GPH). It can run for about 5 hours if propane is used (estimation based on a 20 lbs tank – propane consumption around 0.94 GPH). Since the H08053 has a THD of about 25%, it shouldn’t be used to power devices that are sensitive to noise.
The control panel features the following 5 AC outlets: Duplex 120V 20A (5-20R); 120V 30A (L5-30R) receptacle; 120/240V 30A (L14-30R) receptacle; 120/240V 50A (14-50R) receptacle.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 H08053 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.
In the H08053’s control center, there is a handy meter that shows voltage, frequency, and lifetime hours.This helps you keep an eye on its status and activity.In addition to this information, there is a light that lets you know when the oil level is too low.The generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank.From a safety point of view, the product has a circuit breaker for overload protection and an automatic shut-off for low oil, so you can use it without worry.The Firman H08053 comes with the standard paperwork and an owner’s manual that will help you get the device up and running quickly.It also comes with a funnel, tool kit, oil and propane hoses.
The Firman H08053 has a traditional, open frame that measures L30.2 x W27.5 x H26.3 in, This frame gives it support and lets it be lifted off the ground.The device was made to work well in harsh conditions and in the great outdoors.The generator is technically “portable” in the sense that you can move it, but at 212 pounds, it may be hard to move it by hand.It is hard to move around, but its wheel kit (dia:10) makes it possible “Once it’s on the floor, it will be easier to move because of the handle that folds down.
The following charts show how some of the most important features of the Firman-H08053 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 H08053 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).
