The cable makes no siginificant. The embedded magnet is sufficiently strong, but he's just used within the rubber plug and thereby loose. He then slips out or pushes the rubber plug from the charging contacts, whereby the charging operation is stopped. I do not understand why you have because not a drop of glue used. So the customer has to repair itself and stick to the magnet that then.
The seller is recommended however. The first cable did not even work. After brief contact me replacement was sent.
For Bastelfreunde can recommend this cable, for all others rather not.
