If I remember I will.

I personally don't think the rating in the description is anything as good as they say, but it is much better capacity than the little thing I use to pump up my car tyres at the moment, and the PM works well with that one.

If I do make a walker using PM there will be at least 12 of them working in groups of 3 with this unit I might not need much storage capacity. Remember I am thinking of using the system at a maximum of 50psi.
