This manual provides instructions for the ESR MagSafe Sticker 360 Universal Magnetic Ring. This product is designed to add MagSafe compatibility to your existing phone case, enabling the use of MagSafe accessories and enhancing wireless charging capabilities.

2. Setup and Installation
Follow these steps for proper installation of the ESR MagSafe Sticker 360 Universal Magnetic Ring:
- Prepare the Surface: Ensure the back of your phone case is clean, smooth, and flat. The ring is only compatible with PC or TPU cases without a non-slip coating.
- Use the Alignment Guide: The included alignment guide is crucial for precise placement. Insert the installation tool into your phone's charging port.
- Position the Ring: Place the alignment guide over the phone case. Select the appropriate template for your phone model (iPhone or Samsung Galaxy) to ensure correct positioning of the ring over the wireless charging coil.
- Apply the Ring: Peel off the adhesive backing from the magnetic ring. Carefully place the ring onto the designated area on the outside of your phone case, using the alignment guide.
- Secure the Ring: Press the ring firmly onto the case and hold for a few seconds to ensure strong adhesion. Wait at least 2 hours before using the phone with MagSafe accessories to allow the adhesive to fully set.
Important Note:
- The ring must be stuck on the outside of the phone case. Sticking it inside the case will affect magnetism.
- The ring is not suitable for leather phone cases, liquid silicone cases, or cases with uneven surfaces.
- Once installed, the ring can be removed but cannot be repositioned effectively.

5. Troubleshooting
If you encounter issues with your ESR MagSafe Sticker 360, consider the following:
- Weak Magnetic Connection:
- Ensure the ring is applied to the outside of a smooth PC or TPU case.
- Verify that your phone case is not made of leather, liquid silicone, or has an uneven surface, as these materials are incompatible.
- Confirm the ring was installed using the alignment guide to ensure it is centered over your phone's wireless charging coil.
- Overheating During Wireless Charging:
- Ensure your phone is properly aligned with the standard wireless charger. Misalignment can lead to inefficient charging and heat generation.
- Ring Detachment:
- Ensure the case surface was clean and dry before application.
- Allow the adhesive to cure for at least 2 hours before applying stress or attaching accessories.
