I work in a web development company and we have many mobile devices that we need to test our software on.

We charge these devices each with their own adapter plugged into a socket, but that clutters up the place a lot. We'd like to use some sort of extension cord that has multiple USB ports that can charge all of these devices.

We bought a 10 port USB hub with its own adapter to charge all these devices, but it itself needed to be connected to a computer or else it would not power the devices. We don't want to keep a PC powered up just to be able to load the devices.

My question is: does anybody know of a multi USB (10+) power supply that:

  1. Can load multiple devices at once (preferable even multiple power hungry devices like tablets)?
  2. Itself can be connected to one wall socket to get power ?
  3. Does not need a computer to be able to start loading the devices?

if it just needs to be a device, maybe use a raspberry pi, or maybe a USB OTG cable from one of your test devices to get your hub to detect a host device? –  Journeyman Geek Sep 17 '13 at 15:32
    
I tried to connect a usb cable to the usb in port on the hub, but that did not help. Are you saying there exists some other usb device other then a full fledges pc that would do the trick? I'd prefer to not use a pi, but some small usb plug would work for me. Any suggestions? –  koenp Sep 17 '13 at 15:37
    
well the pi comes to mind cause its small and cheap, and well, is a computer where it matters. –  Journeyman Geek Sep 17 '13 at 15:42
    
VTC: 1) We don't do product suggestions, 2) This has nothing to do with a computer as defined in the help center. –  Ƭᴇcʜιᴇ007 Sep 17 '13 at 16:40
