A durable wrap-around hand truck frame and 10 in. wheels help protect the unit while making it easy to transport. An Automatic Voltage Regulator ensures reliable and consistent power while preventing damage to the generator and the devices plugged into it. The easy-access control panel has four 120-Volt 20 Amp (GFCI Protected) outlets and one 240-Volt 30 Amp Twist Lock Outlet to meet all your power needs. (source: Ryobi (opens in a new tab))

Zoom on the Ryobi RY906500S

In summary, the Ryobi RY906500S is a portable generator especially useful for:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to be able to deliver results, even during a power failure

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 RY906500S in use

The Ryobi RY906500S

The Ryobi RY906500S houses a 420 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 6500W along with a peak wattage of 8125W.

The generator is rated for a noise of 72 dBA (just slightly more noisy than a dishwasher). Its starting mechanism is based on Ryobi's EasyStart pull-start mechanism (more information below).

Thanks to a fuel capacity of 6 gallons, the RY906500S can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH).

Outlets

The control panel features the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Since the RY906500S bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The Ryobi RY906500S has a conventional, open frame design, of the following dimensions: L39 x W29 x H24.5 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 195 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). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed 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 RY906500S's control panel

The RY906500S 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.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the LED on the sensor will flash red and the generator will automatically shut down. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Ryobi RY906500S also is packed along with the following accessories: tool kit and oil.

Emissions

The Ryobi RY906500S 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 Video

The Ryobi RY906500S versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY906500S compare to generators of similar power (between 6000 and 7000 W).

  • At a weight of 195 pounds, the Ryobi RY906500S places in the expected weight range of the generators in the 6000-7000 rated wattage range. In terms of weight, one of the champions in their power range is the Sportsman GEN85KIDF, standing at just 133 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 72 dBA. For those who are looking for a less noisy device, we suggest the Powerhorse 7500i. With just 55 dBA, it is one of the most quiet devices in this power range.
  • As for its autonomy, the RY906500S, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Generac XC6500, reaching around 14 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. Standing at an estimated 0.6 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the Lifan ESI 7000iER-EFI is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 6000-7000W generators, the Ryobi RY906500S 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.

Who makes the engine for this generator. (Asked July 13, 2019)

The 420cc engine of the Ryobi RY906500S is manufactured by Ducar.

What type oil is recommended for the RY906500S? (Asked April 24, 2020)

For general, all-temperature use, SAE 10W-30 is recommended.

Can you get in inverter to connect with the model RY906500S? (Asked June 10, 2020)

Unsure what you are trying to achieve. This unit outputs AC power. An inverter converts DC into AC. If you need clean power, you should consider an inverter generator.

Both my oven and A/C need 50 amps. Will this unit be able to run my oven and A/C during a blackout? (Asked June 14, 2020)

This unit does not feature a 50-amp outlet. Assuming that you were talking about their combined draw, and that they both operate on 120V, you'd be pulling 6000W out of the 6500W. As we recommend to keep the load under 80%, you should be looking at a unit able to deliver around 7500 running watts.

How many gallons does it use per hour? (Asked July 09, 2020)

Fuel consumption depends on load. At 50% load, it should be around 0.6 gallon per hour.

Is this unit OK to operate in the rain? (Asked August 03, 2020)

Please refer to our article on rain and snow operation, which applies to any existing unit.
