The Devia EL255 Magnetic Adapter Ring enhances your device's compatibility with MagSafe accessories. By attaching this ring to the back of your phone or phone case using its strong adhesive, you can securely connect to MagSafe chargers, mounts, and other accessories. This adapter is particularly useful for devices or cases that lack built-in MagSafe compatibility, allowing for seamless integration with MagSafe technology. It is important to note that the adhesive is designed to work on most cell phone cases; however, it may not be compatible with silicone, textured, or anti-fingerprint coated cases.
