Using Dropbox with the iPad

Had a question. Since my iPad will not recognize any cable or charger, I can't sync it up with itunes, because my computer will not recognize the iPad (or the iPad won't recognize the computer).

So I'm relegated to using Dropbox to load up books, PDFs and comic books and then importing them into iBooks or Comic Glass.

My only issue with this is that I have to do them one at a time which is a pain in the ass. There HAS to be a way to wirelessly transfer multiple files at a time to the iPad right? Or automatically sync the dropbox files onto the iPad.
