With its powerful and flexible dual-fuel technology, the Firman H05752 can put out 120/240V. Even though it runs on gasoline, it has a running wattage of 5,700W and a peak wattage of 7,125W. It runs on propane and has a rated power of 5700 watts and a starting power of 7125 watts. The noise level of the generator is set at 74 dBA (Slightly louder than a shower). It has a pull-start mechanism, which is a common way to start a motor. With a full tank of gasoline and an 8-gallon fuel capacity, the H05752 can run for about 12 hours at 0.5 load and a 0.5 load (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). Due to its relatively high THD (25%), the H05752 can’t be used to power sensitive electronic devices.
There are 6 AC outlets on the control panel: two 120V 20A (5-20R) GFCI duplexes, a 120V 30A (L5-30R) receptacle, and a 120/240V 30A (L14-30R) receptacle.Even though this Firman generator is not RV Ready, an L5-30P to TT-30R adapter can be used to easily connect it to an RV.The H05752 is also ready for a transfer switch because it has a twist-lock L14-30R receptacle.If the power goes out, you can easily connect it to a breaker box and keep your home running.
The status and activity of the H05752 can be easily checked on the control panel, which has a meter that shows voltage, frequency, and lifetime hours.In addition to this information, 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.As far as safety goes, the device has an automatic shut-off for low oil and a circuit breaker for overheating, so you can use it without worrying.Along with the basic paperwork and an owner’s manual, which will help you start the generator right away, the Firman H05752 comes with a tool kit, a funnel, an oil hose, and a propane hose.
The Firman H05752 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 generator is built to work well outside and in rough places.Even though the generator is technically considered to “be portable,” it will be very hard to move it by hand because it weighs 176.5 pounds (in the sense that it is 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-H05752 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 H05752 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).
