USB hub question

[Eiolon]

I work at a library and we are going to be checking out MP3 players to patrons. When they come back we will need to charge them. I was thinking about getting a USB hub and connecting it to a computer. Would there be a limit to how many MP3 players (Creative Zen) that could charge from a USB hub?

Also, I am looking for a hub with lots of ports. 7 ports seem common but I found a 13 port one. Any larger ones out there?

should work since its self powered.. you probably wouldnt even have to plug it into a computer to charge any of the mp3 players.. and even so you could connect multiple ones to a system since its self charged.. just use double sided tape to stack them so they dont clutter the counter top..
