Description
Zoom on the Ryobi RY903622
In a nutshell, the Ryobi RY903622 is a portable generator mostly geared towards:
- RV travellers looking for even more independence
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Ryobi RY903622 is powered by a 212 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3,600W as well as a peak wattage of 4,500W.
At a noise rating of 72 dBA (just slightly more noisy than a dishwasher), the generator is started via Ryobi's EasyStart pull-start mechanism (more information below).
The RY903622 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.4 GPH), due to its fuel capacity of 4 gallons.
Outlets
The control panel features the upcoming 5 AC outlets:
This Ryobi generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').
Portability
The Ryobi RY903622 has a conventional, open frame design, which offers support and allows it to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 115 lbs make it incredibly difficult to manually lift and transport. However, this lack of maneuverability is compensated by its wheel kit (⌀8.5") and its folding handle, with which you can conveniently shift it, once it's 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:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
Features
The RY903622's control panel
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.
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Ryobi also included some oil in the RY903622's packaging.
Emissions
The Ryobi RY903622 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, making it usable in forested areas.
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).
- Since the generator weighs in at a dry weight of 115 lbs, the Ryobi RY903622 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- As this generator has its lowest possible noise of 72 dBA, it should be considered noisier compared to its peers of a comparable running wattage. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500DF. With just 52 dBA, it is one of the most quiet devices in this power range.
- As for its autonomy, the RY903622, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4500DF, with a fuel consumption of 0.23 GPH could be in your good books.
Price comparison
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Ryobi RY903622 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
The bottom line
- In the expected price range
- CO DETECT technology
- RV Ready
- Decent weight (115 lbs)
- Decent fuel efficiency
- No data center
- No electric start
- Not CARB-compliant
- On the noisy side (72 dBA)
- Relatively low run time
