That's what happens to all my Anker cables one after another. I've opened one failed cable's connectors and it looked like a design problem: The micro USB connector's metal jacket is really short and not properly anchored inside the connector (it is attached to 2 plastic hooks inside). Once it's bent too much, those hooks loosen and the two steel springs lose their tension and retract.
