I bought three of these cables. They are the worst I have owned. I have tried with multiple devices and multiple sockets. In nearly all instances, it is not guaranteed that the charging will actually begin. Often times I need to slightly unplug the device, or slightly unplug the socket, in order to get the charging to start. Even then, when I put the device down, the charging also stops. I will order a different brand and then send these to the trash. Terrible!
