With the Apple Watch Magnetic Charger to USB Type-A Cable you can quickly and easily recharge your Series 1-5 Apple Watch from almost any computer's USB Type-A port or (optional) wall charger. The magnetic pad for the Apple Watch combines Apple's MagSafe technology with inductive charging. Unlike other wireless charging methods, this charging pad is forgiving in that it does not require precise alignment. Just let it magnetically snap to the back of your Apple Watch and you're done.
