... These cables seem good quality (rigid enough so tanks can imagine, gold pins, ...) but actually NO! Used to connect with an external battery on the anker 2A port, my SGS4 faster discharge load it when GPS is active. If I connect with a cable that was lying noname home, the phone manages to reload without concern despite heavy use. The concern is about the same in data mode: the transfer of the latest ROM took several hours with this cable, so it took a few minutes with another cable! Really disappointed obliged to use for the charger "nightstand" when the charging time less bother me.
