Power & Run Time

The Ryobi RY904500

Featuring a 212 cc OHV 4-stroke engine, the Ryobi RY904500 operates using gasoline, providing 120V, with a running wattage of 3,600W and a starting wattage of 4,500W.

With a noise rating of 82 dBA (just slightly more noisy than an alarm clock), the generator features a manual recoil starter system.

With its 4 gallons fuel tank, the RY904500 can operate for around 10 hours at 50% load when fully fueled (with fuel usage averaging around 0.4 GPH).

Outlets

The control panel includes the following 5 AC outlets:

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

120V 30A (TT-30R) receptacle

This Ryobi generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

At L24 x W26 x H20 in, the Ryobi RY904500 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The design is ideal for rough environments and demanding outdoor use.

Despite its weight of 115 lbs, the generator is considered 'portable,' signifying its capability to be moved, albeit its heaviness may hinder easy transport. Still, once it is on the ground, its wheel kit (⌀8") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

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

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.

Beyond the regular documentation and owner's manual (opens in a new tab) for quick start, 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.
