The cable does what it should, it invites the S3 easily on. Furthermore, the cable is too short, so you do not need great pull apart and there is no voltage, which could damage the microUSB.
So maybe that's the cable that it was too short a bit car dependent, I do not know!
Anyway, that's mumbi charging cable with the mumbi universal mount an unbeatable combination, and not too expensive!
Clear Kaufemphelung!
