Zoom on the Ryobi RY903600
In summary, the Ryobi RY903600 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Homeowners in need of an emergency backup power for their essentials
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Ryobi RY903600's design includes a gasoline-fueled 212 cc Ryobi 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 features Ryobi's EasyStart pull-start mechanism (more information below).
The fuel capacity of 4 gallons allows the RY903600 to operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.4 GPH).
Since the RY903600 has a high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Ryobi generator is RV Ready.
The Ryobi RY903600 has the following dimensions: L24 x W26 x H20.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
As the generator's weight is 113 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit (⌀9") and its folding handle, with which you can conveniently shift it, once it's on the ground.
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
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Ryobi RY903600 also comes with some accessories: tool kit and oil are included.
The Ryobi RY903600 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, so it is adequate for use in forested areas.
The Ryobi RY903600 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY903600 compare to generators of similar power (between 3500 and 4500 W).
- Having a dry weight of 113 lbs, the Ryobi RY903600 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 72 dBA can be judged as noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen4500DF with only 52 dBA.
- The RY903600's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 10 hours at 50% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 16 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.4 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4500DF, which boasts with a gas consumption of only 0.23 GPH, may be the right generator for you.
The bottom line
- Several accessories included
- RV Ready
- Decent weight (113 lbs)
- Decent fuel efficiency
- No data center
- No electric start
- Not CARB-compliant
- On the noisy side (72 dBA)
- Relatively low run time

does the generator have a fuel cutoff to switch on to let run till all is out of the carberator? (Asked January 24, 2022)
The unit does not have such feature. Tank and carburetor must be drained manually. Procedure is explained page 16 of the owner's manual (opens in a new tab).
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.
Purchased mine in 2017 when I went on the road with my RV. This little gen ran almost none stop for three years!! Burned 12 gal. of gas a day powering everything in my RV through the winter and summer. I made reg. oil changes and brush changes. Used reg. gas without “gas treatments”, just filtered the gas with a funnel that had a screen in it, plus reg. gas filter changes. Never had a single problem with my carb the whole time!! Any gas powered device left to sit for long will clog…. I got my $350 worth out of this little Ryobi generator!!!
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
