Got a few of these for around the house. Need desperately to throw them out. Fits flimsily into any equipment I've tried, making charging unreliable at best, if not non-existent. At first I thought fault was due to my phone jack, but have tested with tablet & PS4 controllers, all can't be charged unless I'm holding them or have been stacked ‘just right’. (Those devices charged fine with quality cables btw). These cables just don't seem to fit firmly into the battery jacks.
