The ASUS ROG Tessen is a wired mobile gamepad designed specifically for Android devices, connecting via a USB Type-C port to ensure a responsive experience with a 500 Hz polling rate. Its physical build features a telescopic aluminum bridge and a foldable hinge, allowing it to securely hold phones up to 7 inches wide and between 7 and 14.5 mm thick. To keep your device powered during long sessions, it supports 18W fast pass-through charging, so you can plug your charger directly into the controller. Control is handled through a combination of metal dome mechanical switches for the D-pad and face buttons, providing a tactile feel, alongside two analog sticks with a 22° movement range and a taller 18 mm right stick for precision. For more advanced play, you can use the two programmable aluminum rear paddles or customize your layout via the Armoury Crate app. The black chassis is accented by Aura RGB lighting with seven preset effects, and the package includes rubber support pads of different thicknesses to ensure a snug fit for various phone models.
