Universal MagSafe Conversion Kit

This two-pack adds MagSafe compatibility to standard PC or TPU phone cases, letting owners of recent iPhone and Samsung Galaxy models use magnetic accessories. The adhesive-backed rings work with iPhone 12 through 17 series, Galaxy S25 models with a magnetic case, and Google Pixel 10 devices. Installation is permanent once applied, so the case must be free of non-slip coatings.

Ultra-Thin Fiberglass Build

Each ring measures 2.24 inches in diameter and only 0.04 inches thick, adding 3 grams per piece without bulk. The fiberglass-and-magnet construction triples magnetic holding force compared with a basic sticker, keeping the phone locked to chargers, stands and mounts during daily handling. The slim profile sits flush inside the case, preserving wireless charging on standard Qi pads when the phone is centred correctly.

Guided Installation Tools Included

An alignment clip removes guesswork during fitting, with labelled cutouts for iPhone 17, 17 Pro, 17 Pro Max and iPhone Air models. Once the ring is pressed into place it cannot be repositioned, so the guide ensures a single accurate application. The kit upgrades any compatible case to MagSafe without cables, batteries or extra hardware.

Questions about this item

Does the MagSafe ring support 25 W wireless charging speeds?

The ring itself does not set a power limit; it only adds magnetic alignment. Actual charging speed depends on the wireless charger and phone, which may reach 25 W when properly aligned.

What case thickness and material will the 2.24 in adhesive ring bond to?

The adhesive works on PC or TPU cases without a non-slip coating. It will not stick to silicone, leather, glass or textured surfaces.

How do I use the included alignment clip so the ring sits centred on an iPhone 15 Pro?

Place the clip over the phone's camera cutout, press the ring into the clip's centre window, then remove the clip. The ring cannot be repositioned once applied.
