Make charging your Apple Watch utterly effortless. And now, it charges up to 33% faster when paired with Apple Watch Series 7, so you can reach 80% charge in about 45 minutes.¹ 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. Other models will have regular charging times. ¹Testing conducted by Apple in August 2021 using preproduction Apple Watch Series 7 (GPS) and Apple Watch Series 7 (GPS + Cellular) with Apple Watch Magnetic Fast Charging USB-C Cable (Model A2515) and Apple 20W USB-C Power Adapter (Model A2305), as well as Apple Watch Series 6 (GPS) and Apple Watch Series 6 (GPS + Cellular) with Apple Watch Magnetic Charging Cable (Models A2255 and A2256) and Apple 5W USB Power 44 Apple Accessories Copy and Legal Disclaimers, September 2021 Adapter (Model A1385); each Apple Watch paired with an iPhone, all devices tested with prerelease software.
