I have bought countless OTG adapters and they either seem to read a USB drive or allow for charging. But not both. And I don't mean at the same time obviously.
All I want to do is plug in an OTG adapter (rather than a cable which dangles around) into my tablet and plug in my USB flash drive to read files. When the battery is low, I want to unplug my USB drive and just put in a standard USB type A cable to charge the device. But every OTG adapter I have got (including one from Integral) does not allow a charging current through to the device.
Its really frustrating because I have to keep disconnecting the OTG adapter to charge the device using a USB cable directly. And this will potentially ruin the USB port on the tablet.
How can I solve this?
