USB-C to MagSafe 3 Cable (2 m) – Apple
MagSafe 3 charging cable adopts a separate design and is not integrated with the charger, so it is easy to use and maintain.
The output end is a MagSafe 3 connector, and the input end is a USB-C connector.
The connector does not have an extended protection design. There is a green LED charging indicator on the MagSafe 3 connector.
MagSafe 3 connector has five spring contacts.
The jacket of the cable is made of nylon woven.
The charger is either 67W, 96W, or 140W, depending on the model of Mac. You can use the USB-C power adapter (or one that’s more powerful) that Apple includes in the box.
The 14-inch MacBook Pro comes with either a 67-watt (for the M1 Pro with 8-core CPU model) or 96-watt power adapter (for the other M1 Pro or M1 Max models), while the 16-inch MacBook Pro requires you to use Apple’s brand new 140-watt USB-C power adapter, which happens to be the most powerful adapter that it has ever made.
