The MagSafe Ring itself does not contain magnets. It's used for automatically aligning your phone with your MagSafe wireless charger and mounts for easy place-and-go.

The magnetic strength of the Ring is over 1,800 g, ensuring your phone stays securely attached to all MagSafe accessories.

 Please check:

• When using other third-party chargers, ensure the wireless charger has a strong magnetic attachment.
• The ring must be installed on the back of the case, not the inside.
