the charging circuitry is in the phone and battery cells, not the wire that plugs into your computer or the wall.
I can't tell you what to do, but I use random usb cables and plug the one up into random things.
Example, there are VOIP phones at the job that have USB ports. I plug the phone in there.
there are vector scopes (google it) at the job with usb ports on them. I plug the phone there.
i have a usb plug in my CAR! i plug it there..
so as far as my experience goes, I use many different cables, but prefer the ones from monoprice.
so do what you do...
