Am looking at using my old Android phone for a second receiver…
Have used OTG’s etc etc in the past, but I’m blowed if I can find an OTG cable that…
a) has a single USB socket, and
b) actually powers the phone as well
(All those I’ve seen on ebay and Amazon say they only power the attached USB devices - not the phone?).
Can someone share a link to a source of known-powered OTG’s like this?
