Review: So far, so good! - Great product, not used it fully yet but I have used a blow gun on it to “dust” those places you can’t get at. Tested it with a 16 gauge nailer and it coped with no problem. Waiting on a new tyre inflater but I see no problems with it coping with that ether! If you want a small, very portable air source to blow, inflate or turn your air nailer cordless, this is great. If you want to use power tools or spray then this is not for you. (I do intend to test it with a 1/4 & 3/8 air ratchet to see how it does but I suspect it will not keep up! I wouldn’t even try anything bigger.) Only down point (as far as I’m concerned) is all my tools needed new euro connectors as mine were all British! Runs quite a happily on a 4 amp battery for all I need it to do (so far!)

### ⭐⭐⭐⭐⭐ Compressor
*by D***H on 28 August 2025*

Excellent product, portable and powerful

### ⭐⭐⭐⭐ Well made, good concept but not as great as it could have been due to small 3.8L tank
*by M***P on 10 August 2024*

This Ryobi tool was a difficult choice. If you want "on delivery" high pressure compressed air for hours on end, this is not for you. This cordless small "tanked" compressor is the only thing between a 12v corded air compressor or the big tanked mains air compressors. This Ryobi would be the perfect tool if they had given it a 6 litre tank. When I'm inflating tyres (top ups) the 3.8 litre tank is fine for a few tyres but once the tank is empty you are directly using the compressor to pump air into the tyre at the compressors speed, ie much lower than when from the tank. This is the only true "cordless" air compressor on the market...I've searched! and for the money, it's a costly purchase for the DIYer but if you want to daily inflate the odd tyre, without having to take the vehicle to the fixed wall air inflator, this tool is perfect.
