Unfortunately match the shape and dimensions of the power plug is not the VDE regulations. So the plug contacts are a little short, and at the connector width missing even a few millimeters. Now you could just reply, what do I care? The main thing that works part! But that's what it does not always do: The different dimensions have in fact means that the device often does not get stuck in the socket, but falls by itself out or sliding out.
In addition, the device without documentation or instructions supplied. Because of the identified shortcomings and the lack of documentation, the power supply in my opinion in the EU would not be allowed to be marketed.
