I have an older version of the 9500 Powerplant and love it! It will air up my 35's from 10psi to 32psi in exactly 2 minutes which I think is great. I tried my Superflow MV-50 and it took well over 5 minutes to air up the same tire and I love that little portable compressor but it can't compare as far as air flow goes.
It is all up to what you want in a winch and a compressor, me I like the fact its all one unit but to each their own.
BTW every battery powered compressor works a little better with the engine running, just my 0.02.
