Power & Run Time

The Ryobi RYi4022X in use

The Ryobi RYi4022X

The Ryobi RYi4022X's engine, 212 cc Ryobi OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3400W and reaches a peak wattage of 4000W.

The inverter generator features Ryobi's EasyStart pull-start mechanism (more information below). It is rated for a noise of 72 dBA (just slightly more noisy than a vacuum cleaner).

Thanks to a fuel capacity of 3.3 gallons, the RYi4022X can operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.28 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the RYi4022X produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).


The control panel features 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').


The Ryobi RYi4022X has a conventional, open frame design, of the following dimensions: L25 x W15.88 x H21.75 in, 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.

The RYi4022X can be taken anywhere with you, thanks to its weight of 85 lbs. Moreover, its wheel kit and its folding handle will allow you to effortlessly shift it once it's on the ground.

EasyStart Mechanism

ryobi easystart starting 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

The RYi4022X's control panel

A light indicator allows you to instantly see if its oil levels are insufficient.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Ryobi RYi4022X also comes with some accessories: tool kit and oil are included.


The Ryobi RYi4022X is CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

Product Videos

The Ryobi RYi4022X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RYi4022X compare to generators of similar power (between 2500 and 3500 W).

  • Weight-wise, the Ryobi RYi4022X has only 85 lbs, which renders it one of the lighter generators which produce 2500 to 3500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • Among the generators of a comparable running wattage, this inverter generator with a lowest noise of 72 dBA can be judged as noisy. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • Given that the RYi4022X reaches an autonomy of around 12 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Honda EB4000X, which is able to run for 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. At an estimated fuel consumption of 0.28 GPH (gallon per hour) at 50% load, this inverter generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Ryobi RYi4022X is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

The bottom line

  • Inexpensive
  • CO DETECT technology
  • Several accessories included
  • RV Ready
  • Inverter
  • Lightweight for its kind (85 lbs)
  • Fuel efficient
  • Decent run time
  • No data center
  • No electric start
  • No parallel ports
  • On the noisy side (72 dBA)

  1. 2.5

    My experience has been poor so far. Setup was relatively easy but when I added fuel, I quickly discovered a pinhole in the fuel line as a puddle of gasoline began forming under the generator. The hole was located between the fuel filter and shutoff valve so the only way to stop it was to clamp the hose. So far, I cannot operate the generator and I have yet to determine how to resolve the problem. No relief for this power outage. Bad marks for Ryobi.

    + PROS:
    • Specs look good but unable to try it out.
    - CONS:
    • Shoddy quality apparent with bad fuel line.

    Brand new out of the box and it won’t start. Pull the cord and it runs for a total of one second. It’s got oil… It’s got gas. It won’t run.
    Rated as P. O. S. Do not buy this generator

    I have the same problem – my RYOBI is new out of the box (August 2020), full of gasoline and oil, pull the cord – runs for 1 second, then it dies. Can’t see what the problem is. Purchased from Home Depot, but they seem to want me to return the generator for an exchange – but that is nuts, it is full of gasoline and oil now and will leak all over the place if I try to transport it. Think I will call my golf cart guy, he may be familiar with small gasoline motors. Please let me know if you find out there is some secret switch that needs to be turned on to keep it running.

    I have always like Ryobi, but this may be a deal breaker to stop me from purchasing more Ryobi items

    + PROS:
    • nice price
    - CONS:
    • New out of the box, wont start

    I bought one of these at Home Depot in early spring 2020. Assembled and filled with oil, did not test it. August 10th we had a Derecho or inland Hurricane in Iowa and power went out for a couple days for me (I was lucky). Anyway, I poured gas in the generator and it started on first pull, probably used it 20 hours or so(?), it powered an old side by side refrigerator, and 2 chest freezers, a light and charged our cell phones and mostly ran on low speed. I love it, wish I could figure out how to run two of them to get 240v to run the whole house. I highly recommend this item.

    + PROS:
    • Light weight, small and easy to maneuver, runs the essential items well, used hardly any fuel, just loud enough to know it’s still there, but quiet enough not to bother neighbors.
    - CONS:
    • Can’t run in parallel or combine to get 240 volt output.

Following 3 step and first pull it’s run for over 3 hours with 1 freeze and refrigerator plus one big fan Wish RYOBI put a EXTRA FUEL VALVE in case not want to run empty whole gas tank ,because I don’t want to leave extra gas in gas tank may cause problems for next time .

    Purchased 1/12/2021. Assembled, put oil & gas in it, started on first pull. It’s quite a bit louder than fully enclosed style, but I was willing to make the trade off for the money. Once you get around 20’ away (especially on other side of shrubs or landscaping) it’s really not that bad — quieter than my lawnmower. I purchased to keep 2 refrigerators & 2 freezers running during power outage. I’ve only used it for about 30 minutes but it works well so far

    + PROS:
    • Price & power output
    - CONS:
    • None so far
