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.

Peak Design Universal Adapter — Add Magnetic Desk Mounts to Any Phone Case
The gist: A slim adhesive tile that brings Peak Design’s SlimLink mounting system to your existing phone case, turning any rigid case into a one-click dock for desk and car mounts.
- Case-agnostic: Bonds to smooth, rigid cases (hard plastic, metal back) via 3M VHB tape — so you keep your existing case and still get magnetic mounting without replacing it.
- Wireless charging friendly: At 2.5mm thin, the adapter doesn’t block Qi or MagSafe pads — your phone still charges on a desk Qi charger with the adapter attached.
- Full SlimLink access: Connects to Peak Design’s desktop arm mounts, tripods, and wall mounts — the same ecosystem used by their Everyday Case line, now available for any phone.
- Reliable adhesion: 3M VHB tape anchors the adapter to hard case backs; Light and Matter confirmed “the adhesion is strong in all cases” across diverse surfaces.
Light and Matter reviewed the full Peak Design Mobile line and found the Universal Adapter’s adhesion “strong in all cases” — a useful data point before you commit to permanent attachment.
Best for: Remote workers who want SlimLink desk mounts but use an older phone model or prefer a non-Peak-Design case. Skip it if: Your case is silicone or leather — 3M VHB doesn’t bond reliably to soft or porous surfaces. Runs around $29.95 — check the current price before buying.
