I have one of these, to charge my tablet from my phone charger:- http://www.amazon.co.uk/gp/product/B009ZQKMDA/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 and one of these to upload from an SD card reader to my phone:- http://www.amazon.co.uk/MOFRED®-Mic...UTF8&qid=1413990323&sr=1-1&keywords=otg+cable Both do their seperate jobs well. Is there an adapter that will replace the PortaPow to allow data coms from the phone OTG cable; saving me having a tablet OTG as well?
