iOttie's MagSafe ring adapter allows you to bring the power of MagSafe to any smartphone. Simply attach the magnetic ring to the back of any smartphone or case, and you'll be able to take advantage of the magnetic power of MagSafe no matter which phone you have. The ring uses a super strong 3M adhesive, while an included alignment guide helps to ensure it's positioned in the optimal location for wireless charging. The magnetic ring is made of powerful N54 magnets, which provide a secure connection to any MagSafe-compatible charging stand, wallet, phone grip, or MagSafe car mount. Unlike metallic rings which conduct heat during wireless charging, iOttie's Magnetic Ring Adapter stays cool for an optimal charging experience. The Magnetic Ring Adapter has a smooth finish with rounded edges. Not designed for use with metallic, glass, or textured phone cases. Once attached, the ring can be removed, but not repositioned. Do not attach the ring to the front of your phone, or inside your phone case. Each package contains two (2) magnetic ring adapters, along with two (2) sets of cleaning wipes, and an alignment guide.
