With the ASUS ROG Tessen, you can play all your favorite games from an Android smartphone with a controller. You can easily click your Android smartphone in the controller without removing your case. On the back of the controller, there are 2 extra aluminum paddles. You can program these via the Armoury Crate app, so you can respond even faster in-game. Thanks to the 18W power of the controller, you can also charge your smartphone while you game. That's useful if you're going on a trip, for example. Done gaming? Easily fold ROG Tessen and store it.
