Is it USB 3.0?

I know USB 2.0 standards are 500ma per port but USB 3.0 can go up to all the way up to 5A
Seeing that it is a Mac I bet they make each port at least 2.1 Amp to be able to charge the iPad on it.

Edit: A lot of USB 2.0 ports have high Amps to enable you to charge your phone etc... Often it is 1 dedicated port on your laptop that will have a lightning bolt on top of it.

yeah this is a MBP mid-late 2012 with USB3... that explains a lot about allowing for the ipad to charge

Isn't that a little bit to much for a single USB?

Thought I'd give it a try before putting them on a USB powered hub through an old windows pc.

Got these beautiful babies off amazon.co.uk

separated the individual usb ports with a bit of cardboard, stuck an elastic band around them and voila!
