After receipt and use (for 2 days), it turns out that a face of lightning connector makes connection whims (charge indications and untimely disconnection) while the other side not. It is important to say that my iPhone is in a very thin shell of silicon (1mm) but I connector overlaps, but once out of the shell there is no any malfunction on either side of the connector.
In so see over time if I'd hit the same disconnection problem further comment noted 1 or 2 stars.
EDIT:
After careful observation of the tip, it appears to be slightly twisted sideways. Exchange asked, waiting for a new cable.
