Description
The RYOBI 3600 Watt Portable Generator is the ideal power solution for recreational use, jobsite power, and running household essentials during a storm.
Zoom on the Ryobi RY904500
To sum up, the Ryobi RY904500 is a portable generator tailored for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.
Power & Run Time
Ryobi RY904500 runs on gasoline, powered by a 212 cc OHV 4-stroke engine, delivering 120V, boasting a running wattage of 3,600W alongside a starting wattage of 4,500W.
With a noise rating of 82 dBA (just slightly more noisy than garbage disposal), the generator features a manual recoil starter system.
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:
With its TT-30R receptacle (TT as in 'Travel Trailer'), this Ryobi generator is RV Ready.
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. However, the limited maneuverability is remedied with its wheel kit (⌀8") and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.
Features
Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing 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.
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).
- Having a dry weight of 115 lbs, the Ryobi RY904500 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight is an important consideration for you, the WEN 56432iX stands out as one of the top contenders in this power category, with a dry weight of 52.9 pounds.
- When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 82 dBA is on the noisier side. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen5000DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
- Offering around 10 hours of running time on a full tank at 50% load, the RY904500 is within the average autonomy range of similarly powerful generators. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Firman W03663OF, with around 18 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. Compared to similar devices, this generator is less fuel-efficient than most: it burns around 0.4 gallons of gasoline per hour at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen5000DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W generators, the Ryobi RY904500 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
