I am very happy with this (not very expensive and received 6 days). Asus born not intended dalimenter OTG in the Memo Pad HD7 does-if only for a USB stick. This cable is the solution for connecting (and eating) a storage device OTG on my Asus Memo Pad HD7. I especially appreciate the micro USB connector into food, it's great! No need for a standard USB cable or additional supply: - You plug the power supply of the tablet standard microUSB cable (himself of course the adapter plugged into the tablet sector) to the female connector of the adapter, - You plug the microUSB cable into the tablet, - You plug USB stick or external drive his (the adapter comes with the tablet area provides enough power for my drive). My tablet is rootée (essential) and I use the app "USBOTG Helper" free version. Of course, one has strings attached and is dependent on an electrical outlet, but it suits my occasional use and if necessary I copy the files (photos, video, docs, ...) I need since my external storage device to the microSD.
