Mobile Universal Adapter with Peak SlimLink™
Install this adhesive-backed adapter on the back of a 3rd party phone case to make nearly any phone 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. We call this mounting technology SlimLink™, and it's so fast and secure that it borders on magic. With this adapter on your 3rd party phone case, you can instantly connect to all Peak Design Mobile mounts and accessories. It even works with Apple MagSafe accessories, too.
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.
Our Review
Peak Design Universal Adapter — SlimLink Mounts for Any Phone Case
The gist: A 3M VHB-backed adhesive tile that adds Peak Design’s SlimLink magnetic-mechanical mount system to virtually any rigid phone case — no Peak Design case required.
- Universal fit: Sticks to smooth, non-porous case materials (hard plastic, metal) with 3M VHB tape; works on cases that have no dedicated Peak Design version available.
- Slim (2.5mm): Thin enough that wireless charging still works through the adapter — useful at airport Qi stations or hotel desks without swapping cases.
- SlimLink ecosystem: Once attached, your phone snaps to Peak Design’s bike mounts, tripods, car mounts, and camera straps with the same satisfying click as their full Everyday Case line.
- Weatherproof nylon canvas: 100% recycled fabric withstands outdoor and transit use; the strong magnets tested reliably on metal surfaces from desk to vehicle.
Light and Matter confirmed “the adhesion is strong in all cases” across fridge, metal desk, and tool box surfaces — real-world testing that covers most travel scenarios.
Best for: Travelers who prefer their existing case or have a phone model without a dedicated Peak Design case, but still want the mount ecosystem. Skip it if: Your current case is silicone or leather — the 3M adhesive won’t bond reliably to soft surfaces. Runs around $29.95 — check the current price before buying.
