Top Amazon Reviews

🚀 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
  • 🔧 Doesn't come with hose & fitting
  • 🔄 Can be confusing to operate initially

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.


  • Great for the environment and pocketbook.
I use it for small projects, especially when I need the equivalent of a few cans of air spray. It works out great. It is an air compressor. It is not "silent"....

  • 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

  • Decent
Suppose it's ok for the size. Handy but takes a while to air up tank and depletes quickly.

  • 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

  • Surprised some people. Have extra batteries. Good thing though.
For the size its pretty great. Used as intended its brilliant. Filling big tires or running high flow tools might take some time. Have backup batteries. No issues with delivery.
