The 85W MagSafe 2 Power Adapter features a magnetic connector. So, if someone trips over it, the cable connection simply detaches without your MacBook Pro falling. This also prevents wear and tear or damage to the cable over time. Furthermore, 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 for maximum cable length. The compact wall adapter, also included, is perfect for travel.
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.
This power adapter charges the lithium-polymer battery when the system is switched on, off, or in sleep mode. It also powers the device when you are not using it on battery power.
Compatible with the MacBook Pro with Retina display.
