OK, we've ruled out bicycle pumps... but you've piqued my curiousity about other types of pumps that I have around the house (and not my daughter's stilettos). What about pumps for: 1) balloons, 2) exercise balls, or 3) basketballs?

The object of the original exercise was to determine if a bicycle pump could be adapted to pump air into a BA air mattress. Yes, it can. I've done it. But 20 breaths or air is certainly easier for me and more expedient... and I'm not worried about "bugs" growing in my insulated air core.

However, if I were to have to carry something extra -- and today's "orange" air quality alert, high temperature/high humidity, and my asthma is making that 20 easy breaths feel like 20 breaths at the top of Mt. Everest -- I'd probably want something I could shove down the side of my pannier, or maybe slip into the tent bag, and I'd want it to work FAST, operate easy and be cheap (or free if I had something that I could use already) and able to work with the gear I already like using.
