.... So almost everything is already said. I have read some reviews have criticized a lack of USB or HDMI connection. I then deliberately chose this part because the connections to the unit are delicate and I can not imagine the eternal purity out into the charging station would be good for them. The PlayBook via three pins is loaded but just get the easy contact with the socket. The Playbook is fully charged at a residual battery level prior to 15% in about 2 hours. The Playbook is sure is in the charging station.
