15W charging requires a Qi2 or MagSafe compatible phone: Only Qi2 and MagSafe-compatible iPhones (iPhone 12 and later) will charge at up to 15W on the Qi2 disc. Standard Qi phones will charge at lower speeds. Non-MagSafe phones require a Qi2/MagSafe compatible case or magnetic attachment (not included) to use the magnetic alignment feature.

Apple Watch fast charging (5W) is only supported on Series 7 and later: Fast charging is supported on Apple Watch Series 7, 8, 9, and 10. Apple Watch Ultra and Ultra 2 charge at standard 5W. Earlier Apple Watch models charge at standard speed.

LED will blink if a foreign object is detected: If the LED blinks (Foreign Object Detection), remove any metallic or non-compatible objects from the Qi2 or AirPods charging surfaces and replace with a compatible device.

Keep away from water and other liquids.
