Zoom on the Ryobi RY906500S

In a nutshell, the Ryobi RY906500S is a portable generator mostly geared towards:

  • 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 in need of safely powering high-intensity work or lighting equipment

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's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6500W and reaches a peak wattage of 8125W.

At a noise rating of 72 dBA (just slightly more noisy than a dishwasher), the generator is started via Ryobi's EasyStart pull-start mechanism (more information below).

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

Outlets

The control panel features the upcoming 5 AC outlets:

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

Because the RY906500S is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The dimensions of the Ryobi RY906500S, which are L39 x W29 x H24.5 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 195 pounds. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

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

Panel of the Ryobi RY906500S

The RY906500S's control panel

To help you monitor the RY906500S's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

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).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Ryobi RY906500S's package also includes these 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 thus, may 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).

  • Having a dry weight of 195 lbs, the Ryobi RY906500S belongs in the expected weight range for generators which produce 6000 to 7000 rated watts. 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. 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 Powerhorse 7500i, whose lowest noise levels reach just 55 dBA.
  • The RY906500S’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 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 Generac XC6500, with around 14 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.6 GPH (gallon per hour) at a 50% load. If you wish to further improve in the area of fuel efficiency, the Lifan ESI 7000iER-EFI, which boasts with a gas consumption of only 0.38 GPH, may be the right generator for you.

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.

What kind of gasoline does it use? Is just regular unleaded or a mix? And which mix? (Asked August 26, 2020)

Gasoline should be unleaded, with no more than 10% ethanol. The engine is 4-cycle, so gas shouldn't be mixed with oil.

Can you convert this generator from gas to natural gas? Is there a certain converter kit you need to make this happen? (Asked August 27, 2020)

There are no official conversion kits.

what is the oil capacity on model RY906500S generator? I purchased new and without oil. However, a bottle of oil came with the unit. It is 32 fluid ounces. How much do I put in the generator? (Asked August 28, 2020)

Engine oil capacity is approximately 32 fl. oz.

Is there a special kit to purchase to attach to breaker box (Asked October 04, 2020)

The L14-30R outlet allows for an easy connection to a majority of transfer switches. This connection should be done by a licensed electrician.
