Description
The RYOBI 3,600-Watt Portable Generator is the perfect power solution at home or on the jobsite. This generator delivers 3,600 Running-Watts and 4,500 Starting-Watts of power. Equipped with a simple 3 step starting process start your generator with ease.
Zoom on the Ryobi RY903622
To sum up, the Ryobi RY903622 is a portable generator tailored for:
- RV travellers looking for even more independence
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
The Ryobi RY903622's design includes a gasoline-fueled 212 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3,600W and also a peak wattage of 4,500W.
With a noise rating of 72 dBA (just slightly more noisy than a vacuum cleaner), the generator's starting mechanism is centered around Ryobi's EasyStart pull-start mechanism (more information below).
With its 4 gallons fuel tank, the RY903622 can operate for around 10 hours at 50% load when fully fueled (with fuel usage averaging around 0.4 GPH).
Outlets
The control panel provides the upcoming 5 AC outlets:
The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Ryobi generator RV Ready, ideal for providing power to recreational vehicles.
Portability
The standard open frame design of the Ryobi RY903622 provides stability and easy maintenance access to components, as well as good air circulation. This type of design is ideal for tough environments and heavy outdoor use.
Though weighing 115 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit (⌀8.5") and its folding handle, which facilitates shifting once the generator is set on the ground.
EasyStart Mechanism
Ryobi's 3-step EasyStart mechanism
The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
Features
The RY903622's control panel
Considering security aspects, the generator boasts an automatic low oil shut-off and an overload protection (circuit breaker), offering peace of mind throughout operation.
It also benefits from Ryobi's CO DETECT technology, which is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the generator will automatically shut down.
Alongside the typical set of documentation and owner's manual (opens in a new tab) to assist with setup, Ryobi has included some oil in the packaging of the RY903622.
The Ryobi RY903622 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY903622 compare to generators of similar power (between 3500 and 4500 W).
- With a dry weight of 115 lbs, the Ryobi RY903622 falls within the expected weight range for generators in the 3500 to 4500 rated wattage. If weight is a key factor for your needs, the Genmax GM4600iAEFIC is noteworthy for being one of the top contenders in this power range, with a dry weight of 58.4 pounds.
- This generator, with its lowest noise level at 72 dBA, is noisier than most generators of comparable running wattage. If you'd like a less noisy alternative, the Westinghouse iGen5000DF is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
- Autonomy-wise, with around 10 hours on a full tank at a 50% load, the RY903622 is on the low end when compared to other generators of a similar power output. If extended autonomy is what matters most to you, the Predator 4375 could be an excellent choice, offering one of the longest run times among units in its power category, reaching around 16 hours.
- While the run time is an important parameter, it is dependent on the fuel tank's capacity and thus, doesn't say much on its own unless we consider fuel consumption as well. With an estimated fuel consumption of 0.4 GPH at a 50% load, this generator aligns with the average gasoline usage range of comparable products. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen5000DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.
The bottom line
- CO DETECT technology
- RV Ready
- Decent weight (115 lbs)
- Decent fuel efficiency
- No data center
- On the noisy side (72 dBA)
- Relatively low run time

User Reviews
Knocks like crazy and all I hear from home depot is they don’t know why it does it. I ask can you replace it because I purchased it 2 and a half years ago and told it has been discontinued but you can buy this one for 6 hundred dollars and we may be able to pro-rate it. First time I have had issues with h.d. in 18 years. I won’t use them again
Used maybe about 10-15 times in a few years. Always used ethanol-free gas and kept fuel additive in to stop water condensation. Within 2 year we were having issues with starting and just finally figured out why. The tank had rusted and clogged the carburetor so now I have to replace the tank and carb at a cost over $150. We HAVE to have a generator to keep some pumps running to stop flooding. Fixing it for now but will be replacing soon. NOT HAPPY.
Not bad, but you MUST use gas treatment in your gas or this Ryobi will clog up instantly …funny that I asked this when I bought it and the salesperson said “no, regular gas works fine”…nor was in mentioned in the instruction manual. Since we never know when we’ll need a generator, my warranty expired before i knew this…so the second time I tried to start itwas a total failure
