    5. Can't charge iPad over a USB port
    First I tried it on my USB hub, then on the powered USB port on my MacBook Pro, but nope...no juice—not even when the iPad's syncing with iTunes. Looks like the only way to charge the iPad, apparently, is using the included AC wall adapter. Good thing the iPad's battery is rated for 10-plus hours.


    Is this true? I just read it over on Yahoo!

    Depends on your computer. My early 2009 iMac can charge it fine (in the sense there is no 'not charging' message and the charge meter increased)

    Doesn't charge with a 2009 or so Mac mini. Disappointing, but I guess it just means I won't be syncing that often.

    Try leaving it for a while with the screen off. I don't think a lot of USB ports can both charge the device and power the screen.

    I think you just need a over voltage USB port. My iPad charges when connected to my MacBook Air because it has more voltage for the external SuperDrive. Also charges when plugged in to the back of the LED Cinema Display which also can power the external SuperDrive. However if I plug it into my Hub it will not charge.

    Charging via power point is 2x faster, regardless if it works via USB. I'd stick to the power point.

    DEPENDS ON COMPUTER

    Reports are that it works only with recent Macs at this time.

    If it doesn't work with your computer, use the included USB charger.

    I read a blog that it wouldn't charge on his 2006 Mac Pro but would charge on his 2009 MacBook Pro 13" Haha. I love that if someone pays 20k for a pimped out 06 Mac Pro back then and then recently i pay 1.5K on a 13" Pro computer mine is more capable than his lol:D

    It charges on any port as long as it is asleep.

    Supposedly it takes twice as long to charge even from a high powered USB port when compared to the wall charger.

    Apparently false.

    Some hubs, computers won't charge the device while in use, but if you put it to sleep or let it go to sleep it will very slowly charge the device.

    More powerful usb sources will be able to charge it while being used, and for best performance use the included adapter and wall outlet.
