    I have a 2011 mini and was wondering if the USB charges at full speed?

    The iPad will not charge over a USB cable connected to any computer. You must use the wall plug it comes with or another charging device. When you plug it into a computer, it says "Not charging" at the top.

    Doesn't say it on mine. What you are talking about only occurs on standard old USB ports with only .5 amps or 500mA. I believe that on current macs and probably most pc's the USB can supply up to 2.1A or 2000mA but I am not sure if this is true hence the post.

    Charge ? Yes
    Full speed ? No

    My iPad2 takes at least 2 more hours to fully charge on my mid 2010 iMac comparing to the wall charger ...

    Regards

    Don't overlook Google. You can use System Information to see how much power your USB port is providing with your iPad connected.

    I think you may be confusing Macs with Windows PCs.

    My iPad 3 charges quite happily when plugged in to my 2011 iMac.

    The USB ports are not natively enabled to supply enough power for an iPad on a Windows PC, but you can download a small program (Asus AI Charger) that runs in the taskbar and will charge the iPad.

    You can USB charge but it's NOWHERE near as fast as when wall-mounted.

    My iPad 3 actually loses charge while USB charging if I'm using it.

    No one was saying it was.

    When connected to what?

    You misunderstood.

    I was saying that no one had said that charging on a computer was faster than charging via a wall plug.


    Is the MB also plugged in to the mains when the iPad is plugged in, being used and losing charge?

    Either way, if you're using it and brightness is up etc, it's quite possible it will lose charge if it's taking more than its being given.

    Oh okay, of course I wasn't under the impression that it was (nor do I expect it to be).

    ----------

    Yeah it is.

    I think overall it's pretty useless to try and charge the iPad 3 using a MacBook. It's takes too long when you're not using the iPad and it's practically impossible when you are. The iPad's battery is (thankfully) too big :)

    I agree.

    My iPAd 3 charges just fine hooked up to my 2011 iMac, whether I'm using it or not!

    I did not know this! Thanks for the info. I'm happy charging the iPad in its dock.
