Description

The RYOBI 3600 Watt Portable Generator with EasyStart technology is where efficiency meets convenience. With a Heavy-Duty 212cc OHV engine, this generator delivers 3600 Running-Watts (4500 Surge/Starting-Watts) and is powerful enough to be used on a jobsite or as an emergency backup system. Featuring the EasyStart 3-Step starting system and a large 4 gallon fuel tank, the RYOBI 3600 Watt Generator can run up to 10 hours at 50% load. The Quick-Release handle provides easy and compact storage while the flat-free wheels and the Hand Truck Frame design allow for easy transport, even over rough terrain. This generator is also equipped with an Automatic Voltage Regulator that provides consistent power. The Control Panel features (4) 120-Volt 20 Amp outlets and (1) 120V AC 30 Amp RV receptacle to meet all your power needs.

Zoom on the Ryobi RY903600

In a nutshell, the Ryobi RY903600 is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • 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 in use

The Ryobi RY903600

The Ryobi RY903600 is powered by a 212 cc Ryobi OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,600W as well as a peak wattage of 4,500W.

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).

With a fuel capacity of 4 gallons, the RY903600 may run for around 10 hours at 50% load with a full tank (fuel consumption around 0.4 GPH).

The quite high THD (<20%) of the RY903600 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Ryobi generator is RV Ready.

Portability

The Ryobi RY903600 has a conventional, open frame design, of the following dimensions: L24 x W26 x H20.5 in, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 113 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is 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.

EasyStart Mechanism

ryobi easystart starting 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:

  1. Put the engine switch on the “ON” position, and place the lever on the “START” position
  2. Pull the recoil until the engine runs
  3. Let the engine run 15 to 30 seconds and place the lever on the “RUN” position

Features

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

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 and therefore, can be used in forested areas.

Product Videos

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

    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

    + PROS:
    • Runs

    • You name it

    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.

    + PROS:
    • Nice while it worked. For ONE season.
    - CONS:
    • Metal tank creates condensation

    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!!!

    + PROS:
    • Well built, great price for 3600 watts.
    • Maintance parts easy to get (brushes, recoil, etc.)
    - CONS:
    • No cons.... It totally did it's job!!! Read the instructions and do the maintance!

    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

    + PROS:
    • decent price
    - CONS:
    • never told it needed gas treatment to operate
