Description
Zoom on the Ryobi RY903600
In summary, the Ryobi RY903600 is a portable generator especially useful for:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners in need of an emergency backup power for their essentials
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Ryobi RY903600 houses a 212 cc Ryobi OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3600W along with a peak wattage of 4500W.
With a noise rating of 72 dBA (just slightly more noisy than a dishwasher), 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 somewhat high THD (<20%), it is advisable to not use it for the powering of sensitive electronic devices.
Outlets
The control panel includes the following 5 AC outlets:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Ryobi generator is RV Ready.
Portability
The design of the Ryobi RY903600 is a typical, open frame, with the dimensions of L24 x W26 x H20.5 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 113 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀9") and its folding handle, which will ease its displacement, once it is on the floor.
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
To help you monitor the RY903600's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Ryobi RY903600 also comes with several accessories, including: tool kit and oil.
Emissions
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, which makes it suitable for use in forested areas.
Product Video
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).
- With a dry weight of 113 pounds, the Ryobi RY903600 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 72 dBA is on the noisier side. If noise emissions are one of your priorities, you may be interested in the Cummins Onan P4500i, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- Regarding its autonomy, the autonomy of the RY903600, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides 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. As this generator uses an estimated 0.4 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Ryobi RY903600 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Inexpensive
- Several accessories included
- RV Ready
- Decent weight (113 lbs)
- Decent fuel efficiency
- No electric start
- Not CARB-compliant
- On the noisy side (72 dBA)
- Relatively low run time

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
