Zoom on the Ryobi RY904500

In short, the Ryobi RY904500 is a portable generator adequately designed for:

• RV travellers looking for even more independence
• People occasionally participating in sporting competitions, open-air performances and outdoor festivals
• Homeowners in need of an emergency backup power for their essentials

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The Ryobi RY904500

The Ryobi RY904500's core is the 212 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3,600W and a peak wattage of 4,500W.

The generator is rated for a noise of 82 dBA (just slightly more noisy than an alarm clock). Its starting mechanism is based on a traditional recoil pull-start mechanism.

Thanks to its 4 gallons fuel tank, the RY904500 can run continuously for around 10 hours at 50% load on a full tank (with an average fuel consumption of approximately 0.4 GPH).

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R)

120V 30A (TT-30R) receptacle

The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Ryobi generator RV Ready, ideal for providing power to recreational vehicles.

Portability

With dimensions of L24 x W26 x H20 in, the standard open frame design of the Ryobi RY904500 provides stability and easy maintenance access to components, as well as good air circulation. The device has been designed for tough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 115 pounds. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀8") and its folding handle, enabling easy shifting once the generator is set in place.

Features

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

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 RY904500.

The Ryobi RY904500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY904500 compare to generators of similar power (between 3500 and 4500 W).

• At 115 lbs in dry weight, the Ryobi RY904500 fits well within the typical weight bracket for generators producing 3500 to 4500 rated watts. If weight is a key factor for your needs, the Genmax GM4600iAEFIC is noteworthy for being one of the top contenders in this power range, with a dry weight of 58.4 pounds.
• When compared to other units producing a similar running wattage, this generator and its lowest emitted noise of 82 dBA stand out for being on the louder side. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen5000DF with only 52 dBA.
• As for its autonomy, the RY904500, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. If prolonged run time is essential to your needs, you could consider the Predator 4375, which offers one of the highest autonomy among devices with similar power output, lasting around 16 hours.
• Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. When operating at 50% load, the generator's fuel consumption is estimated at 0.4 GPH, placing it within the average range of gasoline usage among similarly powerful devices. To prioritize fuel savings, we advise considering the Westinghouse iGen5000DF, which stands out for its gasoline efficiency, consuming just 0.23 gallons per hour.
