Second purchase, this time about "handynow". It was the same Adpater delivered, even with identical serial number, for it now but in schluderigen plastic bags and be boisterous surface. Does not work, also returned.
Third purchase directly from "Amazon". Packaging back in (total of 3) plastic bags, but reasonably tidy, no scratches on the housing we previously. And the best part: This adapter works and invites my 10.1N. The adapter looks just like the previous two, but has a different serial number. The label is printed, but the other way around (with the non-functioning adapters shows the 12V peak to the right, if you read the label, in the functioning it shows to the left).
