🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

These reviews highlight that this portable compressor is highly valued for its convenience and lightweight design. It is efficient for inflating tires, especially for off-roading and RVs, though it may be a bit slower than desired. Many users have noted that it fits well within a larger system of Ryobi tools, however, it seems the unit does not come with any accessories like hoses or fittings.

Pros

  • 🚗 Great for on-the-road tire inflation
  • 🔋 Works well with other Ryobi tools and batteries
  • 📏 Compact and portable
  • 💪 Reliable performance

Cons

  • ⏱️ Takes some time to fill tires

Should I Buy It?

If you’re already a Ryobi user and need a portable option for inflating tires on the go, then this could be a great fit for you. However, be prepared for a slightly slower inflation process, and additional purchases for the necessary accessories like hoses or fittings. If these aren't dealbreakers for you, this compressor is well-rated for its compact size and reliable performance.

    • Just buy it!
This Compressor is pretty good. I was skeptical at first. But this compressor is amazing for me. The speed is good. Gets to the 120psi in maybe 1 minute. The weight is great too, it feels like it probably weighs like maybe 15 pounds. Super compact too. I have it in my trunk and it takes up almost no space. The noise level isn't that bad. Its obviously loud, but not loud enough that you cant hear anything. Its a very manageable sound level. Very durable with the rubber handle and feet and thick air tank. I have a 4ah and an 8ah battery. The battery life is pretty decent with a 4ah battery. I can easily fill all 4 of my tires with half a battery or more left over. If you are even considering an air compressor like this, just get it, its a really great machine for what it is. ... show more

    • Good compact battery powered compressor
Very nice air compressor. It would be nice if they built it with the hybrid power option to be powered from the One+ batteries or a 110v source. Maybe in a new model. Otherwise it's very nice. Fairly quiet, good pressure control and fills quickly. The air volume is acceptable for smaller tasks. It drains batteries quickly. ... show more

    • It works, but It is also very confusing
Its portable, it works but I also find the product to be very confusing... I had to turn the middle nob on it all the way to the right to get it to work, and at first I had no idea how to do that, because it was locked it place. I guess you had to pull it out to turn it? Even then I feel like its only useful for blowing out the dust inside of computers... If you want to air up your tire on the road, sure it could do that... But if you are thinking about using this exclusively for airing up your tires I would recommend another product. This would be an emergency product for if you go on a long trip and get a flat and have to air up your spare tire while on the road. And that is only if you have preped properly to use it in case of emergency... The battery will need to be charge, the pump does not come with a battery either by the way. nore does it come with hoses or anything else... its VERY expensive to get everything that you need for this product over all. And I find that its not worth it... please just go find a normal air compressor somewhere and buy it instead. This ones good but there are much better and much cheaper options out there! Never used it for Nail guns or the like so I have no idea how good it is for those things.... ... show more

    • Does the job.
I’ve used it for three years with no problem. A little slow with car/truck tires but gets the job done. Great for bikes and cycles. No cord is great!

    • it's small and fast at inflation
Bought this for airing up my car, and misc, atv and bike tires . It's good for putting in maybe 3-5 psi in 4 mid size car tires at once. It'll need to catch up with the air usage for car tires as the air tank is small , but I like it because it's small and it's fast at inflation, even if it has to compress more air to keep up with usage, it's doable. ... show more

    • Winterized Bathhouse Water Pipes
I was attracted by the portability, but there are a lot of mixed opinions on the use of this size compressor for blowing out water lines due to the low CFM output. I can now say from experience this lightweight compressor was able to blow out the supply lines in our neighborhood pool's bathhouse including hot and cold water lines of (2) showers & (2) sinks, and cold water lines of (3) toilets & a spigot - on one charge of a generic 6 ah battery (it did die right as soon as I was done with the final fixture, so I'll likely bring an extra battery next year). I placed bowls under the faucet and shower fixtures to ensure water was cleared, and it was. The task was still a pain considering I worked alone so had to crawl in and out to isolate the fixtures, but I'm thrilled with the way this performed. ... show more
