Description
The Firman H07553’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. This generator has a noise level of 74 dBA, which is just a little louder than a shower. It can be started with a pull-start, but it also has an electric starter that is easy to use (battery included). With an 8-gallon fuel tank, the H07553 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 6 hours (on a 20 lbs tank – propane consumption around 0.78 GPH). Since the H07553 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 duplex 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 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 H07553 is also transfer switch ready because it has a twist-lock L14-30R receptacle.You can easily connect it to your breaker box to power your home when the power goes out.Features
The H07553’s control panel has a handy meter that shows voltage, frequency, and lifetime hours.
This makes it easy to keep track of its status and activity.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.The H07553 also has Firman’s CO Alert carbon monoxide shutdown, which turns the engine off automatically when harmful levels of carbon monoxide build up around the generator or when a CO Alert fault happens.It’s a nice extra safety measure, but don’t forget to take your generator outside at all times.The Firman H07553 comes with standard paperwork and an owner’s manual that will help you get the device up and running quickly.It also comes with oil, a funnel, a cover, an extension cord, a propane hose, and a tool kit.Mobility
The Firman H07553 is made with a typical open frame that measures L30.2 x W27.5 x H26.3 in, It provides support and stability and can be raised above ground level.
This type of design is great for tough environments and heavy outdoor use.The generator weighs 212 pounds, so it may be hard to move or transport it by hand, even though it is technically considered “portable” (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.
