Works as described, it allows to connect an external hard drive to a tablet (ASUS MC400 in this case), providing an external power source to the drive, as the tablet it self does not supply enough power. What's more, and contrary to the product description, the tablet is being charged at the same time. I suppose this depends on several factors, such the tablet model and how each tablet reacts to having a device connected to the data connections of the USB port while at the same time an external power source is also connected and/or the power supply user. In my case it works both ways (external drive connected and functioning AND tablet being recharged).
I was getting desperate since I upgraded my old external disk drive, which had a dedicated power supply, to a new Western Digital Passport, which feeds directly (and exclusively) from the USB port, and could not put it to work with the ASUS tablet. Theoretically the power supplied by the tablet would be enough to feed the disk drive, but either the tablet provides lower than nomincal current, or the disk consumes more, either way it didn't work with two different disk drives (Toshiba and Western Digital) I tried. With this cable and the external power supply, it works.
