Needed this adapter to connect a tablet with mini HDMI connector to a wall mounted monitor with standard HDMI cables. It can be easily carried in my “tool kit” bag. It is a little bulky but it’s the result of the mechanical sizes of the connector involved, so it cannot be left plugged when not in use.
