OTG cables that supports charging at the same time
Hi guys can any one suggest an OTG cable that can support charging of the android device at the same time? I looked through Amazon and seems like there are hit and misses, not a perfect one as to what I'm looking for.
Example, I see cables that has 3 ports, 2.0 otg cable to attach to the device, female micro usb 2.0, female 2.0 usb (for attachment of the external device). Sometimes I see the female micro usb is for charging the EXTERNAL device and not the android device (external power for hdd) itself. Sometimes, I see that it only works for usb flash drives and not hard drives. The female micro usb 2.0 never supports a charging of the android device itself.
Anyone uses an exact cable that I am referring to? Like connecting a full 2TB hard drive to an android phone/tablet to watch movies and charge at the same time?
Thanks for all the help guys appreciate it.
