However, "No Case Interference" so not quite true. In the photos here on the product side is not clear, so I was not sure if my silicone case that indeed surrounds the connector, would not stand in the way yet.
The adapter is very much on the case of the Xperia Z1 Compact (especially in the longitudinal direction, minimal even up and down), because I can not push in between the corner of a paper sheet as well.
Fortunately, however, can at least my shell (which is of Moodie) longitudinally a fairly wide strip from the housing free, and each about 1 mm are also up and down freely.
This place is almost fully utilized by the adapter, which I try on my two clients to show images.
The magnet is strong, you can also use the Z1c during charging. And even if it is held vertically, carefully in his left hand, characterized by slight pressure on the adapter. In his right hand, or if the device has been rotated horizontally or otherwise, no pressure on the adapter or the cable is there.
The unit will load quickly, but I have not measured it exactly, is probably just as fast as with the other loading facility.
The LED on the adapter lights up red until the battery is 100% full, only the notification LED on Z1c switches already at 90% to green.
Conclusion: Everything fits in this situation, we have made a good catch.
