- 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 ensure that a power failure will not prevent them from working
In the upcoming sections, you'll discover its power characteristics, the array of outlets it presents, its overall portability, and the additional features it possesses.
Power & Run Time
The Ryobi RY909500 houses a 500 cc OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8,000W along with a peak wattage of 9,500W.
Rated for 85 dBA (just slightly more noisy than garbage disposal), the generator's starting mechanism relies on a standard recoil pull-rope starting mechanism.
The RY909500 boasts a fuel tank capable of holding 6 gallons, allowing it to run continuously for around 7.5 hours at 50% load (with fuel usage averaging around 0.8 gallons per hour).
As the RY909500 exhibits a THD of less than 20%, which is high, it is best avoided for powering sensitive electronic devices.
Outlets
The control panel features the following 5 AC outlets:
Since it boasts a twist-lock L14-30R receptacle, the RY909500 is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.
Portability
Measuring L31 x W29 x H24 in, the classic open frame build of the Ryobi RY909500 delivers stability and easy maintenance access to components, facilitating air circulation. The generator is designed for ideal use outdoors and in rough environments.
While technically classified as 'portable' due to its ability to be moved, the 198 lbs of this generator make manual lifting and transportation incredibly difficult. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀10") and its folding handle, allowing for easy shifting once the generator is placed on the ground.
Features
The control panel of the RY909500 includes a convenient meter, showing voltage, frequency, and lifetime hours metrics, helpful for the monitoring of its status and activity.
Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.
It also benefits from Ryobi's CO DETECT technology, which 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 generator will automatically shut down.
Alongside the typical set of documentation and owner's manual (opens in a new tab) to assist with setup, Ryobi has included some oil in the packaging of the RY909500.
The Ryobi RY909500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY909500 compare to generators of similar power (between 7500 and 8500 W).
- At 198 lbs in dry weight, the Ryobi RY909500 fits well within the typical weight bracket for generators producing 7500 to 8500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM10500XiT with only 123.5 pounds.
- This generator, with its lowest noise level at 85 dBA, is noisier than most generators of comparable running wattage. If noise is a concern for you, you could consider the DuroMax XP9500iH, which is one of the least noisy generators in its power range, rated at 61 dBA.
- The RY909500's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 7.5 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 Champion 100416, with around 12.5 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. When it comes to fuel efficiency among generators with similar wattage, this generator lags behind, with a consumption rate of 0.8 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Powerhorse s10500id, which has a fuel consumption of only 0.59 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 7500-8500W generators, the Ryobi RY909500 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
