Zoom on the Ryobi RY904500

In summary, the Ryobi RY904500 is a portable generator especially useful for:

• RV travellers who wish to upgrade their experience to another level

• Homeowners in need of an emergency backup power for their essentials

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

The Ryobi RY904500

Running on gasoline, the Ryobi RY904500 utilizes a 212 cc OHV 4-stroke engine to deliver 120V, offering a running wattage of 3,600W and a starting wattage of 4,500W.

Operating at a noise rating of 82 dBA (just slightly more noisy than an alarm clock), this generator starts up with a conventional pull-start mechanism.

Featuring a 4 gallons fuel tank, the RY904500 provides continuous power for around 10 hours at 50% load on a full tank (fuel consumption around 0.4 GPH).

Outlets

The control panel features the upcoming 5 AC outlets:

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

120V 30A (TT-30R) receptacle

Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this Ryobi generator is RV Ready, ensuring compatibility with recreational vehicles.

Portability

At L24 x W26 x H20 in, the standard open frame design of the Ryobi RY904500 delivers stability alongside easy maintenance access to components and good air cooling. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 115 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀8") and its folding handle, allowing for easy shifting once the generator is placed on the ground.

Features

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring 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 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 dry, the Ryobi RY904500 is consistent with the standard weight profile for devices ranging from 3500 to 4500 rated watts. if you wish to prioritize weight, the WEN 56432iX is one of the top contenders in its power category, weighing only 52.9 pounds.
• This generator, with its lowest possible noise rated at 82 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If you'd like a less noisy alternative, the Westinghouse iGen5000DF is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
• With a runtime of around 10 hours under a 50% load on a full tank, the RY904500 falls within the average autonomy range among the generators of a similar power. If run time is one of your main concerns, the NorthStar c5500 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 15.1 hours.
• Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. The generator burns fuel at a rate of around 0.4 GPH when running at a 50% load, which is consistent with the average fuel usage of models of comparable power output. If gasoline efficiency is at the top of your list, you may want to have a look at the Westinghouse iGen5000DF, which has great fuel efficiency, with a gas consumption of only 0.23 gallons per hour.
