    With this you can charge your external device (HDD, etc.), but not the tablet:
    Micro USB Male to USB Female Host OTG Power Cable for Samsung Galaxy S4 S3 NOTE2 | eBay

    So at least your HDD would not get juice from the tablet

    I also have the same problem!

    using t100 for music (DJ) I think 8/10 hours of battery life are not sufficient, so I have to connect the power supply + my usb sound card in the same input MICROUSB!

    how to do?

    I am going with this:

    4 Ports Micro USB 2 0 High Speed Hub for PC Laptop Black | eBay

    I did not receive it yet, but I see no reason why it wouldn't work.

    Get a small powerpack that you can velcro to your T100. Anything around 5-7000mAh will give you extra hours - as long as the USB powerpack pushes out 2mA/5V

    That won't allow USB OTG to be used at the same time. There's only one micro b plug on the tablet.

    What's needed is either a USB micro-b Y-cable or a powered hub that can provide enough power to the T100. Something like this: Amazon.com : Micro USB Host OTG Cable with Micro USB Power for Samsung i9100 i9300 i9220 i9250 by AtomicMarket : Computer Usb Cables : Computers & Accessories

    No idea if this specific cable, or any similar ones would work with the T100. It's possible that custom cable might be required.

    These types of cables offer power only to the secondary microusb connected device, like a powered external hard drive. The otg function does not allow power to pass through to the original device without some sort of custom made cable. I've read a lot of threads for different phones looking for this function. Someone actually spliced a cable and created their own. That's the only time I've seen an otg cable charge the original device.

    Okay, that is nifty. Kind of clunky, but still nifty. I've been kind of curious of the same, though I don't really have much of a use case (personally). I don't often need to plug in something to just the tablet portion and battery life isn't much of an issue, so I pretty much don't need to charge it when in use. There might be some edge cases where I need to while in use, but none that I can think of (for me) where I need to charge AND have something plugged in for use in the micro USB port.
