Description
The Ryobi RY905500 has a Ryobi OHV 4-stroke engine that is 420 cc. It gives out 120/240V, runs on gasoline, and has a running wattage of 5,500W and a peak wattage of 6,875W. The generator makes 78 dBA of noise, which is less than a vacuum cleaner. It has Ryobi’s EasyStart pull-start system (more information below ). The RY905500 can run for about 10 hours at 0.5 load on a full tank and 6 gallons of fuel (fuel consumption is approximately 0.6 GPH). Since the RY905500 has a THD of about 20%, it is best not to use it to power electronics that are sensitive to noise.
Outlets
Two 120V 20A (5-20R) GFCI duplexes and a 120/240V 30A (L14-30R) receptacle are among the 5 AC outlets on the control panel. As the RY905500 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you’ll easily be able to connect it to your breaker box to power your home during a power outage.
Features
The RY905500 and its control panel have a handy meter that shows voltage, frequency, and the number of hours the battery will last. This makes it easier to keep track of its status and activity. For safety, the generator has an overload protection (circuit breaker) and an automatic low oil shut-off, so you can use it without worrying. The Ryobi RY905500 comes with oil and a tool kit, as well as the standard documentation and an owner’s manual to get you up and running quickly.
Mobility
The Ryobi RY905500 is 31.5 inches long, 29 inches wide, and 24 inches high. Together with its traditional, open-frame design, they support the generator and allow it to be raised above the ground. This type of design is great for tough environments and heavy outdoor use. Even though this generator is technically “portable” in the sense that it can be moved, it is very hard to move by hand because it weighs 192 pounds. But its wheels and folding handle make it easier to move once it’s on the floor.

- 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.
