This adhesive-backed adapter installs on the back of a 3rd party phone case to make nearly any device compatible with Peak Design Mobile mounts and accessories. At just 2.5mm thick and wrapped in a beautiful weatherproof nylon canvas, the Universal Adapter is low-profile, aesthetically clean, and adheres with 3M VHB for an ultra-strong, ultra-durable connection. Like the Peak Design Everyday Case, the Universal Adapter has a brilliant magnetic/mechanical lock built right into it. This mounting technology is called SlimLink, and it's so fast and secure that it borders on magic. With this adapter on your 3rd party phone case, you can seamlessly attach your device to your motorcycle and trust that you'll have your cell for the duration of your adventure. Adheres to smooth, non-textured, non-porous case materials like hard plastic and metal. Not recommended for soft or rubbery surfaces like silicone or leather. Installing directly on your phone is not recommended. Wireless charging may not be possible or optimal with adapter installed. This adapter contains magnets that may interfere with stylus accessories like the Samsung S-Pen. Not designed for tablets or folding/flip phones.
