Learn how to set up and attach the EDGE® Pro Spare Kit to your phone or tablet for secure magnetic mounting. Step-by-step guide with common mistakes.

Quick answer

Use the EDGE® Pro Spare Kit to add MagSafe compatibility to a phone or tablet by attaching the included metal ring, disc, or plate. Choose the right adapter shape for your device, clean the surface, and press firmly for a secure hold.

Which adapter shape should you use?

The EDGE® Pro Spare Kit includes metal plates, rings, and discs. Plates are best for flat cases or tablet backs, rings work with most phone cases that have a raised camera bump, and discs fit smaller devices or spots where you want a low-profile attachment. The nano suction layers let you reposition the adapter if needed, but they work best on smooth, non-textured surfaces.

How to attach the EDGE® Pro Spare Kit to your phone or tablet

Clean the surface: Wipe the back of your phone case or tablet with a lint-free cloth to remove dust and oil. A clean surface ensures the nano suction layer sticks evenly. Do not use alcohol or wet wipes that leave residue; dry microfiber works best.
Choose and peel the adapter: Select the metal ring, disc, or plate based on your device size. Peel the protective film from the nano suction layer on the chosen adapter. Avoid touching the adhesive side with your fingers — oils can reduce stickiness.
Align and press firmly: Center the adapter on the back of your device or case. Press down from the center outward for 10–15 seconds to remove air bubbles and secure the bond. If you misalign, lift the adapter using the included plate remover within the first minute and reposition. After that, the bond becomes permanent.
Test the magnetic hold: Attach a MagSafe charger or mount to the adapter. If the device wobbles or slides, the adapter may not be centered or the surface may be uneven. Reapply a fresh nano suction layer if needed. A weak hold usually means the adapter is not fully seated — re-press firmly before assuming the product is defective.
