    I will receive my Mini this coming Friday but am wondering has anyone tried seeing if their iPad will charge from a USB port on the new Mini...

    I have been fortunate in that my 3 yr old MBP has enough "oomph" in one of it's ports so I can sync & charge at the same time but - What about the Mini ??

    Searched but could not find an answer....

    Thanks in advance :eek:

    'Standard' USB ports send out 5W.

    Every Mac since the first aluminium iMac can output more than that. It's used for charging the iPad (which needs 10W), and it was originally used to provide more power to the USB ports on the Apple wired keyboards.

    So 'yes', to answer your question.

    USB 1.x and USB 2.0 limit the maximum current on the protocol level, AFAIK.

    The USB 2.0 specification on page 201 in usb_20.pdf:

    You mean 10 Watts, not 10 Volts.

    The USB 2.0 specification does not allow 10 Volts.

    Anybody ?

    Thanks - fully aware that USB supplies only 5 volts - was just wondering if it is supplying the necessary 2.0a ( or 10 watts ) that the iPad needs to charge...

    So does anybody know - perhaps the simplest way if just for someone to plug an iPad into their Mini and let us know ?

    Searched specs and literature high and low and can't find an answer...

    Cheers,

    yes the ipad charges when directly plugged in to the 2011 mini usb.

    however, when plugged into a powered kensington usb hub, it only does the slow trickle charge (says "Not Charging" in the status bar).

    Yes, confirmed. iPad does charge via mini USB ports.
