Beto: JetAir CJA-001S Tubeless Air Tank Inflator- -

I agree with some other comments , just read the instructions to benefit from a very well made item .

The item looked great in the advert and exactly what I needed but.........to charge the tube up you need to be able to attach a track pump valve which you cant do if you have a dual adapter fitting, meaning the item cant be used without purchasing some kind of valve adapter. this should be highlighted in the advert. disappointing and i wouldnt recommend

I bought this product as I carry out a lot of tubeless MTB tyre conversions, and I thought it was about time I bought either a new Track pump with a compressor release chamber or an air tank which was about 40% of the cost of buying a new pump. The tank works ok, but to get optimal inflation for a tubeless setup you need to add a volume of 80psi to get the tyre to inflate to the required 40psi in order to pop the bead. This unit works don’t get me wrong, but my friend has a Topeak pump which does the inflation a bit better. But for now it’s suffice for my needs.

Simple to use and quick to operate. We'll built.

Didn't buy it from Amazon so the review has no bearing on them, but the product itself is poor: the one I received does not hold pressure in the chamber (while the lever is shut) and leaks at a rate of about 20 psi every 30 seconds. This basically means it's nigh impossible to get to the required pressure needed to actually seat a tubless tyre.Thought it might be a lose connection on the unit but found that the hex screws are plastic and instantly threaded.Looking elsewhere on the internet it seems I am not alone in receipt of a leaky model, so I'd advise to go for something else!

Its too expensive
