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!)

Well made, good concept but not as great as it could have been due to small 3.8L tank
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.

Pops tubleless bicycle tyre beads with ease!
I bought this for my bicycle shop to inflate tubeless tyres. It does this perfectly, no more do I have to struggle with a track pump. Turn it on, let it build up the pressure then press the trigger and the tyre pops on and inflates to the desired pressure. - It is small and compact so it can be moved around the workshop with ease and gets put away out of the way when not in use. It recommends 5.0ah batteries but I have used this with 2.0ah batteries fine, being able to pump up multiple tyres on one charge. It even did my van and car pressures, topping up with the smaller battery. The quick connect makes it easy to swap between my tyre inflator and blow gun! Highly recommend this to anyone thinking about using it for bicycle tyres. For those wandering Park Tool do a tyre inflator that fits both presta and schrader valves designed to be used with compressors! (INF-2)

Mostly good
Dose what it says, as other reviews say couldn't do spray painting, takes up far less space than my 40year old clark 50ltrs mains compressor. but all I really do is check,inflate tyres and use a blow gun which is dose OK, with a 4ah battery it builds up in a reasonable time. I got it on discount not sure if I would have paid full price. Overall happy with it

Per usi limitati è eccezionale. Uso domestico pulizia computer ventole o in altri ambienti per usi limitati è di una comodità assurda. Ogni tanto ricordarsi di aprire rubinetto di condensa posizionato sotto al serbatoio. con un pochino di aria interna così da farla spurgare. Almeno ogni 2 utilizzi.

Really good unit, well built. Quieter than expected. Doesn't it into the battery too much. Engine does not have the same power as a cord one but awesome for my needs. Really great if you have other Rioby tools, as you don't need to buy extra batteries.

Forse non a buon mercato ma indubbiamente pratico e valido per i miei lavori di casa e i miei hobbies dove non è richiesta la potenza dei classici compressori. Utilizzo ormai da alcuni anni batterie da 5 che mi offrono una buona autonomia e che condivido con diversi prodotti Ryobi. Per le mie necessità ritengo sia un ottimo prodotto.

Article reçu très rapidement. Très compact, il se transporte dans difficulté sur chantier où à la maison. Selon l'utilisation il faut prévoir une batterie de rechange afin de jongler avec les deux et pouvoir utiliser le compresseur facilement. Je recommande ce produit dans hésiter 👍.
