Ryobi RY903622 - 3600/4500W Portable Generator

Description

Zoom on the Ryobi RY903622

In a nutshell, the Ryobi RY903622 is a portable generator mostly geared towards:

• RV travellers wishing to enhance their freedom and nomad lifestyle
• People occasionally participating in outdoor fairs, festivals or events
• Homeowners in need of an emergency backup power for their essentials

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.

Power & Run Time

Running on gasoline, the Ryobi RY903622 operates with a 212 cc OHV 4-stroke engine, delivering 120V, with a running wattage of 3,600W and a peak wattage of 4,500W.

Rated for 72 dBA (just slightly more noisy than a shower), the generator's starting mechanism relies on Ryobi's EasyStart pull-start mechanism (more information below).

Thanks to a fuel capacity of 4 gallons, the RY903622 can operate for around 10 hours at 50% load with 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

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

The Ryobi RY903622 boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The featured design is ideal for the outdoors and all tough environments.

Though weighing 115 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. However, the constrained maneuverability is addressed with the assistance of its wheel kit (⌀8.5") and its folding handle, allowing for easy shifting once the generator is placed on the ground.

EasyStart 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

The RY903622's control panel

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you 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.

In addition to the standard documentation and the user manual for prompt setup, Ryobi has also included accessory] in the packaging of the RY903622.

The Ryobi RY903622 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY903622 compare to generators of similar power (between 3500 and 4500 W).

• With a dry weight of 115 lbs, the Ryobi RY903622 sits comfortably within the expected weight range for devices generating 3500 to 4500 rated watts. if you wish to prioritize weight, the Genmax GM4600iAEFIC is one of the top contenders in its power category, weighing only 58.4 pounds.
• When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 72 dBA is on the noisier side. 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.
• As for its runtime, the RY903622 runs for around 10 hours at a 50% load, placing it towards the low end among comparable products. If run time is one of your main concerns, the Predator 4375 could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 16 hours.
• Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This generator reaches an estimated fuel consumption of 0.4 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. 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.
