Keeping multiple mobile devices charged can be difficult. Samsung may have the solution with their Power Sharing Cable, which does pretty much what it says: allow charge to be transferred from one device to another. This would be useful if the device you need to use is about to die & no other charging source is available.
If you are thinking of using this, be aware that neither charge, nor discharge is 100% efficient. So there is a significant loss any time charge is transferred between devices.
Perhaps the most likely use is charging a smart watch from your phone.
