Description
With its dual-fuel technology, the Firman H05753 is a powerful and versatile generator that can put out either 120V or 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. This generator has a noise level of 74 dBA, which is just a little louder than a dishwasher. It can be started with a pull-start mechanism or a simple and elegant electric starter (battery included). With an 8-gallon fuel tank, the H05753 can run for about 12 hours at 0.5 load on a full tank of gasoline (fuel consumption is approximately 0.67 GPH). With propane, it can last up to about 5 hours (estimation based on a 20 lbs tank – propane consumption around 0.94 GPH). Since the H05753 has a THD of about 25%, it shouldn’t be used to power electronics that are sensitive to noise.
Outlets
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. With an L5-30P to TT-30R adapter, this Firman generator’s L5-30R receptacle makes it easy to connect it to an RV. But it’s still not ready for an RV. The H05753 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.
Features
The status and activity of the H05753 can be easily checked on the control panel, which has a meter that shows voltage, frequency, and lifetime hours. In addition to this information, if the oil level is too low, a light on the device will show. The generator has a built-in fuel gauge that makes it quick, easy, and convenient to check how much gas is in the machine. 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 H05753 comes with basic instructions and an owner’s manual to help you start the generator quickly. It also comes with a propane hose, tool kit, funnel, and oil, among other things.
Mobility
The Firman H05753, which is L30.2 x W27.5 x H26.3 in and has a typical open frame design, is stable and can be raised above ground level because of its size and shape. 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 194.5 pounds. But its wheel kit (dia:10) makes up for the fact that it is hard to move around “) and a folding handle that makes it easy to move once it’s on the ground.

- 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.
