Unfortunately electronics isn't my thing, so I had a look on google but frankly I got more confused than before, and read that i need to make sure I use the right voltage otherwise I screw the phone battery: so, my question is, which output should I use with my OPO phone, and, more generally, which output is used for which device? Is there a rule of thumb of some kind?
