It just works until the plastic housing on the receptacle cracks, and you can no longer get a good electrical connection.  The big problem is that the jack acts as a lever that can transmit enough force into the receptacle to destroy either one or the other rather than breaking the connection.<p>And the more ring conductors you want to add, the longer the lever can become.<p>I have been really happy with all my devices that have standardized on USB for charging.  In contrast, Apple&#x27;s proprietary 30-pin and Lightning (and MagSafe, while I&#x27;m at it) just make me think they&#x27;re being colossal dicks, doing whatever TF they want, rather than meaningfully contributing to a standards consortium and licensing their patents to it.
