Zoom on the Ryobi RYi4022X

In a nutshell, the Ryobi RYi4022X is a compact portable inverter generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Camping and tailgating hobbyists looking for a portable power source

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 RYi4022X houses a 212 cc Ryobi OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3400W along with a peak wattage of 4000W.

The inverter generator is rated for a noise of 72 dBA (just slightly more noisy than a shower). Its starting mechanism is based on Ryobi's EasyStart pull-start mechanism (more information below).

With a full tank, the RYi4022X can operate for around 10 hours at 50% load (fuel consumption around 0.33 GPH), thanks 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.


The control panel provides the upcoming 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 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 design is ideal for rough environments and demanding outdoor use.

The RYi4022X can be taken anywhere with you, thanks to its weight of 85 lbs. 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'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 serves to show you when the oil level is too low.

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 includes a carbon monoxide sensor. This sensor 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 LED on the sensor will flash red and 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).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Ryobi RYi4022X also is packed along with the following accessories: tool kit and oil.


The Ryobi RYi4022X is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

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. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • As this inverter 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 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 10 hours with a full tank and at 50% load, it is placed 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 Honda EB4000X, with around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This inverter generator reaches an estimated fuel consumption of 0.33 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. 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 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 sensor
  • Several accessories included
  • RV Ready
  • Inverter
  • Lightweight for its kind (85 lbs)
  • Decent run time
  • Decent fuel efficiency

  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.

    - CONS:
    • Won't start

    After Laura hurricane, buy at Home Depot on Sept ,03 /2020 .Out the box assembly and fill a oil and gas about 1gallon! 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 .

    + PROS:
    • Easy transport
    - CONS:
    • No problems
