Its purpose, namely the Sony Xperia Z1 charge on the magnetic connector that meets the cable, but it is unfortunately regrettable that the USB connector is equipped with extremely soft sheet as a guide. During transport (possibly even before) a pointed object press on the metal connection seems to have exercised so that it bent and deformed arrived. I have the dent with a screwdriver itself again bent slightly outwards in order to plug the connector in a charger at all can. "Thanks," the dubious quality of the soft sheet which also succeeded, but with all the geometry has changed even further. Nevertheless, the contact with the charger seems to be sufficiently because the mobile phone is charging. Possibly I would, however, prefer to invest a little more, if I again need such a cable. A charger itself is unfortunately not part of the delivery.
