I work in a webdevelopment company and we have many mobile devices that we need to test our software on. iPad, samsung S2, S3, S4, iPhone 3, 3S, 4, 4S, 5, nexus 7, Blackberries, etc etc.
We charge these devices each with their own adapter plugged into a socket, but that kinda sucks and clutters up the place. 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...
- can load multiple devices at once (preferable even multiple power hungry devices like tablets)
- itself can be connected to one wall socket to get power
- does not need a computer to be able to start loading the devices.
