The Firman H05754’s dual-fuel technology lets it put out 120/240V and gives it a lot of power and flexibility. If it is powered by gasoline, the device has a running power of 5,700W and a starting power of 7,125W. If it’s run by propane, it has a rated power of 5700 watts and a starting power of 7125 watts. The generator has a simple pull-start mechanism that has been used for a long time. It has a noise level of 74 dBA (slightly noisier than running a dishwasher The H05754, 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 (on a 20 lbs tank – propane consumption around 0.94 GPH). Due to its high THD (25%), the H05754 is not a good choice for powering sensitive electronic devices.
The control panel has 6 AC outlets: two 120V 20A (5-20R) duplexes, a 120V 30A (L5-30R) plug, and a 120V/240V 30A (L14-30R) plug.Even though this Firman generator isn’t quite RV Ready, an L5-30P to TT-30R adapter makes it easy to connect it to an RV.The H05754 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.
In the H05754’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.The generator has a built-in fuel gauge that makes it quick, easy, and convenient to find out how much gas is in it.As for safety features, the device has a circuit breaker for overheating and an automatic shut-off for low oil, so you can use it without worry.The Firman H05754 comes with a funnel, tool kit, oil and propane hoses, as well as a standard set of instructions and an owner’s manual to get you going quickly.
The Firman H05754 is a standard, open-frame generator with dimensions of L30.2 x W27.5 x H26.3 in, This gives the generator stability and lets it be raised above ground level.The design works well in rough places and for hard outdoor use.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).Still, because of its wheel kit (dia:10 “Once the generator is on the ground, it is easy to move thanks to its wheels and folding handle, which make up for its lack of maneuverability.
The following charts show how some of the most important features of the Firman-H05754 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 H05754 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).
