The original Apple Watch Magnetic Charging Cable was available in two versions, a white plastic back and a steel back. The Magnetic Charging Cable that shipped with aluminum Apple Watch models had the white plastic back, and Magnetic Charging Cables included with Stainless Steel and Edition models had the steel back. When purchased separately, the Magnetic Charging Cable used the steel back.
This 1-meter version of the Apple Watch Magnetic Charging Cable has a USB-A plug. A version is also available with a USB-C plug, referred to on Apple’s website as an Apple Watch Magnetic Charger to USB-C Cable. These cables were available in three lengths, 0.3 m, 1 m, and 2 m.
Although not an official “MagSafe” product, Apple refers to MageSafe technology in the description:
“We wanted to make charging your Apple Watch utterly effortless. So we arrived at a solution that combines our MagSafe technology with inductive charging. It’s a completely sealed system free of exposed contacts. And it’s very forgiving, requiring no precise alignment. You simply hold the connector near the back of the watch, where magnets cause it to snap into place automatically.”
This Apple Watch Magnetic Charging Cable is shown below along with a 42mm Apple Watch Edition Series 2 (white ceramic case).
