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. (source: Ryobi)

Zoom on the Ryobi RY903600

In summary, the Ryobi RY903600 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • 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 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 3600W as well as a peak wattage of 4500W.

The generator is rated for a noise of 72 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanism is based on 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).

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

Outlets

The control panel provides the upcoming 5 AC outlets:

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

Thanks to its TT-30R receptacle (TT stands for '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 device has been designed for tough environments and demanding outdoor use.

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 a wheel kit (⌀9") and a folding handle, with which you can conveniently displace 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

The RY903600 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

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.

Besides the classic documentation and a user manual to get you promptly started, the Ryobi RY903600 also comes with some accessories: tool kit and oil are included.

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, which makes it suitable 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).

  • As its weight is 113 pounds, the Ryobi RY903600 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 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 you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500, whose lowest noise levels reach just 52 dBA.
  • Autonomy-wise, with around 10 hours on a full tank at a 50% load, the RY903600 is on the low end when compared to other generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000, 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. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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.
