Overview
Anyone whose phone lacks built-in magnets can stick one of these thin metal rings to the back and gains a surface for magnetic chargers and mounts. The listing calls it an upgrade to MagSafe.
The reason to buy is a simple way to turn an older phone into one that grabs magnetic accessories, with a spare ring in the pack. The limit is the unclear compatibility, since the title names newer iPhones, Galaxy and Pixel models while the spec table lists older iPhone generations. Case thickness is not addressed.
Who it's for
People with a phone that lacks magnetic charging but who use a stand or wireless charger daily are the use. It is not for buyers who need confirmed support for one specific newer model.
Pros and cons
- Thin profile on the phone back
- Two rings in the pack
- Adhesive mount, no tools
- Light at a few grams each
- Compatibility listed two ways
- Case thickness not addressed
- Placement guide not described
Performance notes
The ring gives a ferromagnetic surface that magnets can grip, so holding strength depends on the accessory's magnet and on how flat and centered the sticker is. Adhesive grip depends on a clean, dry surface. A thick case between the ring and the accessory weakens the connection.
