I just bought an A2511 Qi charger. It’s fine, whatever, I won’t return it BUT, the cord is so loose!
I can’t move the charger without the micro USB cord unplugging itself from the unit. Looking closely at it, it looks like the USB receptacle ends behind the plastic cover of the charger, and the plugs micro USB end on the cord is too short to fully seat. The tiniest wiggle of the cord makes it come loose and fall out. Certainly these units have been tested, right?
I think if I cut back the plastic sheath on the cord I might be able to seat the plug a little deeper so it makes a positive connection.
