How to charge 40 devices at once

Hello,



I am new to the site so I'm not sure if this is the correct section to ask my question. However, hopefully someone can help me. I have about 160 small iPhone like devices to charge. I was wondering how I can charge all of them at once. I've looked all over the Internet for usb hubs to charge them all and cannot come up with a practical solution. If anyone has any ideas as to what I can do, please let me know. Also, if I bought 4 of these would it work?

Any advice is appreciated.



Thank you,

Christopher
