The 212cc OHV 4-stroke engine of the Ryobi RY903622 runs on gasoline and can put out 120V. It has a running power of 3,600W and a maximum power of 4,500W. The noise level of the generator is 72 dBA, which is just a little louder than a vacuum cleaner. Ryobi’s EasyStart pull-start system is used to start the generator (more information below ). With a full tank, the RY903622 can run for about 10 hours at 0.5 load on its 4 gallon fuel tank (fuel consumption is approximately 0.4 GPH).
On the control panel, there are 5 AC outlets for: Two 120V 20A (5-20R) and 120V 30A (TT-30R) duplex plugs.This Ryobi generator is ready for an RV because it has a TT-30R plug, where TT stands for “Travel Trailer”.
When it comes to safety, this product has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worry.It also has Ryobi’s CO DETECT technology, which keeps track of the amount of carbon monoxide in the air while the generator is running.If the generator isn’t set up right and carbon monoxide levels get too high, the generator will turn off by itself.It’s a nice extra safety measure, but don’t forget to take your generator outside at all times.In addition to the usual paperwork and owner’s manual to get you up and running quickly, Ryobi also included some oil with the RY903622.
The typical open frame design gives the generator stability and lets it be raised up off the ground.The design works well in rough places and for hard outdoor use.The generator is technically “portable” because it can be moved, but at 115 pounds, it may be hard to move it by hand.Still, once it’s on the ground, its wheel kit (8.5″ diameter) and folding handle can easily solve the problem of low mobility and make the device easy to move.
The following charts show how some of the most important features of the Ryobi-RY903622 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
Originally located in Japan, Ryobi Limited is a firm that has mostly specialized on electrical and automotive components during the course of its existence.However, their relatively new power tool division has gained popularity for the high caliber and dependability of its goods, which can now be found on the shelves of well-known merchants all over the world.The majority of the world’s production locations for Ryobi goods are the US, Germany, Japan, and China.
There is a warranty on the Ryobi RY903622 for up to 3 years.This warranty may not cover all parts of the generator or may only cover certain parts.Ryobi’s warranty policies can tell you more about how long their generators are covered.You can also call their customer service line at 1-800-525-2579.
