Any smartphone can join the Mobile mounting ecosystem with this Mobile Universal Adapter from Peak Design. This square adapter secures to the back of third-party cases and uncased phones via a built-in ultra-strong adhesive. Once attached, your phone can now utilize the full array of Peak Design Mobile magnetic/SlimLink connector mounts and accessories. To help ensure that the adapter doesn't interfere with the daily use of your phone, Peak Design constructed it with a super-slim low profile that's only 0.1" thin. Please note that this adapter will not work on soft cases, such as silicone or leather.
