Description
The Firman H07552’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 7,500W and a starting power of 9,400W. If it runs on propane, it has a rated power of 6750 watts and a starting power of 8450 watts. The noise level of the generator is set at 74 dBA (slightly noisier than running a dishwasher It has both a simple pull-start mechanism and an electric starter that is easy to use and convenient (battery included). With a fuel tank that holds 8 gallons, the H07552 can run for about 12 hours at 0.5 load on a full tank of gasoline (fuel consumption is approximately 0.67 GPH). If propane is used, it can run for about 5 hours (estimation based on a 20 lbs tank – propane consumption around 0.94 GPH). Since the H07552 has a THD of about 25%, it is best not to use it to power electronics that are sensitive to noise.
Outlets
The control panel has 5 AC outlets: a 120V 20A (5-20R) GFCI 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 use with an RV with a 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 H07552 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.Features
The H07552’s control panel has a handy meter that shows voltage, frequency, and lifetime hours.
This helps you keep track of its status and activity.The generator has a built-in fuel gauge that makes it easy to see at a glance how much gas is in the tank.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.The Firman H07552 comes with the usual paperwork and an owner’s manual , which lets you start it right away.It also comes with oil, a funnel, a tool kit, a cover, and a propane hose.Mobility
The Firman H07552, 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 device was made to work well in harsh conditions and in the great outdoors.Even though the generator is technically considered to “be portable,” it will be very hard to move it by hand because it weighs 212 pounds (in the sense that it is movable).Still, its wheel kit (dia:10 “) and its handle that folds up, once it’s on the ground.Product Videos

- 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.
