It can even charge the phone if necessary and the power adapter is powerful enough to charge both phone and the TwinView while playing.
The second screen does not only let gamers play on both screens (if the game supports split screens), but it is also very useful for monitoring live streams, chats, or a tutorial while playing. Users can run any two apps/games simultaneously giving the endless possibilities.
Another great benefit of this is that it also enables the ability to connect the Kunai controllers for a full out console gaming experience.
