The 60W MagSafe  2 Power Adapter (power supply unit) holds magnetically. So if someone stumbles over it, the cable connection simply loosens without your MacBook  Pro falls down. This also prevents the cable from wearing out or damaging over time. In addition, the magnetic connector ensures a quick and secure connection to the system.
 An LED indicator on the top of the connector lights up when the connection is established. Orange means the device is charging. Green means it is fully charged. A power cord is included with the power supply unit for maximum cable length. The compact wall plug, which is also included, is perfect when traveling.
 With its intelligent design, the power supply is practical for on the go, because you can simply wind up the cable and store it easily.
 Compatible with the 13 "MacBook  Pro with retina display.
