MagSafe 3 Charging Cable

Apple's MagSafe 3 charging cable connects a USB-C power adapter to the magnetic port on MacBook Pro and Air models from 2021 onward. The magnetic coupling releases under a sudden tug, sparing the laptop if the cord is caught, while USB Power Delivery 3.1 negotiation supplies up to 140 watts for fast charging. USB-C sits at the adapter end and the proprietary MagSafe 3 connector at the laptop, making the cable a charge-only link rather than a data path. A 2-meter length matches Apple's retail cord. It is used specifically for charging recent MacBook hardware. Genuine and equivalent cables generally cost $40 to $60.
