As it is well-known, Apple has scrapped the MagSafe connector. Thanks Apple, was too good to keep :-(
I'm considering the purchase of one of the many magnetic adapters available on the market. But I've tried this from a colleague and it looks like pins could connect the wrong way when you are fiddling to dock the plug the male in place. The magnet is polarised as to oppose the attempt to connect it in the reverse orientation, so that should be avoidable, but I've tried to slide the two pieces from different angles and I'm afraid it could actually establish the bad contacts.
Am I worrying needlessly? Is a problem of just this item, or a general one?
EDIT: clearly, I don't mean dangerous to myself, I'm just referring to the shock signals that might happen in case the pins are connected the wrong way. I'm already aware of possible physical damage to the frame if one leaves the female tip of the adapter plugged when the laptop is on the move.
