A cheap way to bring MagSafe compatibility to a case that lacks it, provided the case is hard-shelled and smooth, since textured cases like Otterbox's rubber layer weaken the magnetic hold.

Overview
This ESR kit is a pair of adhesive metal rings that add MagSafe-style magnetic attachment to a phone case that doesn't already have it, not a wearable ring. They stick to the outside of a smooth PC or TPU case so MagSafe chargers, mounts and wallets grip normally.
Despite sitting in a wearable-rings category, this is a phone case accessory, a thin metal disc rather than a magnet itself, that lets a MagSafe accessory's magnet grab your case. It only works on hard PC or TPU cases with a smooth back; ESR is explicit that leather, liquid silicone, and bare phones without a case are not supported, and the ring can't be repositioned once it's stuck down.
- 2-pack of metal MagSafe rings for cases without native MagSafe
- Alignment tool and printed templates included for placement
- Dedicated cutouts for iPhone 17, 17 Pro, 17 Pro Max and iPhone Air
- Must be applied to a smooth PC or TPU case exterior, not leather or silicone
Who it's for
Owners of non-MagSafe phones or cases, including many Android phones like Pixel and Galaxy models, who want to use MagSafe mounts, wallets or chargers. Not for leather or silicone cases, bare phones, or anyone who expects to reposition the ring after applying it.
Pros and cons
- Adds MagSafe attachment to non-MagSafe phones and cases
- Strong hold on smooth hard cases, enough for power banks and tripods
- Works with standard wireless chargers too when aligned
- Weak or no hold through textured cases like Otterbox
- Adhesive is hard to remove or reposition once applied
- No official alignment template yet for some newer phones like Pixel 9 or S24/S25 Ultra
Performance notes
The ring is a metal disc, not a magnet, so it's the MagSafe accessory's own magnet doing the pulling; ESR's job is to place that metal exactly where the phone's charging coil sits, using printed alignment templates and a plastic guide tool.

Frequently asked questions
Can I move the ring after I've stuck it on?
No, ESR says the ring can be removed but not repositioned once installed, so placement needs to be right the first time.
