Pair the Apple USB-C To MagSafe 3 Cable with the separately sold USB-C Power Adapter to power your compatible MacBook. The magnetic connection is strong enough to resist most unintended disconnects but will disconnect if someone trips over the cable, preventing your MacBook from potentially falling off a desk and hitting the floor. An LED indicator turns amber when the battery is charging and turns green when it's fully charged. The cable is 6.6' long and is made with a woven design for added durability.
