That is very interesting. I actually use a Slime pump and an adapter made from an old cycle tube but it takes forever and it's a little LOUD for me. I have something similar to this that I need to try again - I wasn't impressed first time I used it. Someone on here did start a thread on a battery powered pump that is very small and seems promising but I can't find the thread now - I might give that a go.
Pumping the pad up aside, it's a really great pad that is very very comfortable.
