Zoom on the Ryobi RY903600

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

  • RV travellers looking for even more independence
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance parameters.

Power & Run Time

The Ryobi RY903600 in use

The Ryobi RY903600

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.

The generator features Ryobi's EasyStart pull-start mechanism (more information below). It is rated for a noise of 72 dBA (just slightly more noisy than a shower).

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).

As the RY903600 has a relatively high THD (<20%), it is not recommended to use it to power sensitive electronic devices.

Several examples of what the generator may allow you to power simultaneously are:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel features the upcoming 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

With its dimensions of L24 x W26 x H20.5 in, the conventional, open frame design of the Ryobi RY903600 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough 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, its challenging mobility is solved by a wheel kit (⌀9") and a folding handle, which will ease its displacement, once it is on the floor.

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:

  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

The RY903600's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

With the basic documentation and a user manual, 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.

Moreover, it features a spark arrestor, making it usable 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. Regarding dry weight, one of the champions in the same power range is the Energizer eZV4500, with a dry weight of only 78 lbs.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 72 dBA can be considered somewhat noisy. If you are concerned with noise, check out the Westinghouse iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As for its autonomy, the RY903600, with an autonomy of 10 hours at a 50% load, is placed on the low end among the generators of its kind. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000, with 16 hours .
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator reaches an estimated fuel consumption of 0.4 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

Price comparison

As you can see from this dynamic 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.
