Steam Controller mounts for smartphones: Mechanism’s Basegrip

Mechanism’s Basegrip lets you attach Valve’s Steam Controller to smartphone mounts, but iOS and Android support remains limited for now.
Valve’s Steam Controller isn’t just about playing on a screen anymore, thanks to a new accessory route from Misryoum.
Mechanism. already known for add-ons like grips for handheld gaming setups. has prepared its first Steam Controller-specific accessory: the Basegrip for Steam Controller.. It’s designed to secure over the back of the controller while still leaving space for the magnetic charging puck to connect. which matters if you plan to swap between handheld and powered use without removing everything.
The idea is straightforward but appealing: with the Basegrip attached. the Steam Controller can work with a range of Mechanism mounts. including the company’s existing smartphone mount system.. In practice. that means you could pair your phone and the controller into a compact “handheld-like” setup. particularly when using the Steam Link app for streaming.
What’s the catch?. Misryoum notes that the Steam Controller’s functionality isn’t universal across mobile operating systems. and support for iOS and Android is described as incomplete.. Valve’s approach keeps the controller oriented around Steam and Steam Link. so smartphone use right now may feel more like an experiment than a fully polished experience. with improvements dependent on future updates.
Even so. the Basegrip points to a broader trend: hardware ecosystems are increasingly modular. letting gamers combine controllers. mounts. and devices in ways that weren’t originally envisioned.. For anyone already invested in Mechanism’s accessory lineup. it also reduces friction. since the company is building the mounting platform to “snap together” across products.
Pricing and timing are also simple.. Misryoum reports the Basegrip for Steam Controller is scheduled to go on sale on May 4. with a standard price and bundle options depending on what else you buy.. Separately. Mechanism’s planned Steam Controller Dock is set to ship in June. offering a charging and display-focused accessory for when the controller isn’t in use.
In the end. this is less about replacing dedicated mobile controllers and more about expanding how and where you can bring Valve’s Steam Controller.. If you already stream via Steam Link. the Basegrip offers a quick way to turn a phone into part of your gaming setup. even if the full mobile experience is still catching up.
