This cable is functioning properly as far as far as the charge itself.
The only complaint would be that the built-magnet is not so really strong. Care should be taken so that you do not inadvertently abuts the cable. In the case of the male jumps out very quickly. Even in low light, it is difficult to place the magnetic plug properly. Since hardly snaps something palpable and only the vibration signals on the smartphone when the cable is seated properly. That should work better for the price.
