In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

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.

Enjoying a noise rating of 72 dBA (just slightly more noisy than a shower), this inverter generator gets running thanks to Ryobi's EasyStart pull-start mechanism (more information below).

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

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

Outlets

The control panel provides the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Ryobi generator is RV Ready.

Portability

The dimensions of the Ryobi RYi4022X, which are L25 x W15.88 x H21.75 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 85 lbs of the RYi4022X's dry weight enables you to use it anywhere you will ever need. Moreover, once it’s on the ground, its wheel kit and its folding handle will allow you to shift it without effort.

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

Features

Panel of the Ryobi RYi4022X

The RYi4022X's control panel

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

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Ryobi RYi4022X also comes with several accessories, including: oil and tool kit.

Emissions

The Ryobi RYi4022X is CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used 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 inverter generators of similar power (between 2500 and 3500 W).

  • Having a dry weight of 85 lbs, the Ryobi RYi4022X belongs in the expected weight range for inverter generators which produce 2500 to 3500 rated watts. In terms of weight, one of the champions in their power range is the Genmax GM3300i, standing at just 47.4 lbs.
  • This inverter generator, with its lowest possible noise rated at 72 dBA falls into the more noisy category, compared to other devices of a similar running wattage. If you are concerned with noise, check out the Honda EU3000iS, which is one of the least noisy generators in its power range, with a noise rating of just 50 dBA.
  • Since the RYi4022X boasts with a run time of around 12 hours at 50% load, it can be safely judged as one of the inverters with the highest run time among those of a comparable output.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. 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 not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Genmax GM3300i. With a fuel consumption of as little as 0.22 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W inverter 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.

    Bought this generator due to outage in my RV park. It seems decent so far.

    + PROS:
    • Anything comparable was crazy expensive, power went out at my RV park. I went to the local Home depot and purchased the first generator with 4000w capacity I could directly plug my RV unit to. Runs fridge, toaster, 1000w microwave oven, and everything needed in my 30 ft Travel trailer on a hot summer day. I have since properly broken in generator and run dry to prep for storage.
    - CONS:
    • It is a bit louder than I would have ever anticipated. I am deaf and it seems loud.
    • I cannot find a maintenance kit on this generator on home depot or online.
    • No tank drain valve to prep generator for long term storage.

    Should have a gas cap fuel gauge. Hook to your house by moving loads in your panel to one phase or the other. Or buy a step up transformer 120 to 120/240v. I’ve read that igens have a hard time with 120/240v unbalanced loading. My igen volts goes from 121v to 127 v during the in rush from my grinder; I like!

    + PROS:
    • Does not bog down with impulse loads.
    • Light weight easy to dodge weather and chain down in truck camper shell.
    • Oil easy to drain and fill.
    • Remote gauge set for volts, Hz, hours easy to find and connect.
    • Open frame easy access.
    - CONS:
    • Gas tank should have fuel gauge and drain.
    • Unit should be parallel capable.
    • The open frame seems a little loud.
    • Unit should have hours meter. Frequency stability is about plus or minus 0.5hz for my unit.

    So far it starts and runs well. I have not needed to depend on it. But have run appliances and my sump pump (main priority) on it and everything starts and runs fine. For the money it seems like a pretty good deal from a major brand.

    Some people are commenting that they are having trouble starting their generator. Setting the auto-idle switch to off seems to make starting easier. Although there is no mention of this in the instruction manual. Just my experience. I won’t say it starts on the first pull every time, but acceptable to me.

    + PROS:
    • Fairly easy to start
    • Good wattage for the money
    • Clean power
    • CO2 shutoff
    - CONS:
    • No gas gauge

    Good product, bought one for hurricane season. Instructions are good. Generator is a very simple user friendly machine. First load was around 900w (8-9amps), fridge, 5.5 chest freezer, LED TV, couple fans. With only one gallon of fuel went 5.25 hrs. So might be we can pass the 12 hrs mark at 50% load. Making arrangements to hook it to the house using the 30 amp plug.

    + PROS:
    • Very user friendly, don't have to be a techy guy to use it.
    - CONS:
    • Little bit noisy to be an inverter, but not too loud.

    Unplug the CO detector. Reading lots of reviews here on that and most likely that’s your issue. Either then get a replacement part or leave it unplugged. Just reach up under and unplug. Hope this helps someone!

    + PROS:
    • Warranty and run time.
    - CONS:
    • Louder than some inverters but it is an open frame style.

    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

    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.

    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

    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

    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.
