If there is a thread about this just point me in the right direction, but I would like to hear from the 800 guys. I found myself in a bad place over the weekend and learned a few things that I must always carry with my kit, one of which is a portable air compressor. I want the best for the motorcycle application and one that would easily plug into the BMW auxiliary ports. Please provide suggestions, and if you used your equipment only once or used it a lot please state that too. Longevity is a must!
