Mechanism Basegrip: the Steam Controller docks to your phone and beyond

Published on May 04, 2026 | Translated from Spanish

Mechanism has introduced Basegrip, an accessory designed to attach Valve's new Steam Controller to mobile phones and other flat surfaces. The idea is to expand the controller's possibilities beyond the PC, allowing its use with Steam Link for gaming on the go. However, initial support on iOS and Android presents limitations that reduce its full functionality.

The Basegrip uses an adjustable clamp system and a base with suction cups to adhere to tables or stands. Its rigid plastic construction aims to provide stability during gaming sessions. However, compatibility with Steam Link on mobile devices is partial; certain advanced controller features, such as analog triggers or touchpads, are not fully implemented in the current versions of the iOS and Android app, which conditions its practical use.

The accessory that holds your controller... and your patience 😅

Because yes, now you can stick your Steam Controller to a phone with a suction cup, exactly what you always asked for to play on the bus. The downside is that Steam Link apps still look at the controller as if it were a strange creature. But hey, you can always use the Basegrip to attach the controller to the fridge while you wait for Valve to remember to update the software. Innovation, they call it.
