Make charging your Apple Watch utterly effortless. Fast-charge your Apple Watch Series 9 and Apple Watch Ultra 2.* Simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically. It’s a completely sealed system free of exposed contacts. And it’s very forgiving, requiring no precise alignment.
 
Fast charging is only compatible with Apple Watch Series 7 and newer models. Other models will have regular charge times.
