How "self-powered" are the LED Cinema's USB ports?

    Apple lists on their website that the USB ports on the LED Cinema Display are self-powered. Does this mean that i can plug my iPod into it and have it charge even if my laptop isn't attached to the monitor?

    I know that with my 23" Aluminum Cinema Display, there was only power to the ports if the monitor was plugged into the computer (which seems stupid, as the monitor *does* have its own power supply...)

    Can anyone with a LED Cinema verify this?

    I don't think so, but don't take my word for it. Ask a Genius at an Apple Store. You might be able to have them try it out if they haven't already.

    I just tried it and it does NOT work for me. I disconnected all plugs from my MB, plugged my iPhone cable directly in the back of the monitor, and nothing. Same with a standard powered hub. So, I wouldn't count on this being your solution... (unless, of course, I've screwed something up -- it's been known to happen)

    I have set up both a LG monitor and a powered hub, neither supply charging power without a computer. Not that Apple is the same way, just speaking from past experience, your chances are low. If you do have a USB AC adapter, you may be able to plug the USB cable from the monitor into that and possibly be able to charge your devices.
