85W MagSafe Power Adapter for 15- and 17-inch MacBook Pro

The 85 Watt MagSafe Power Adapter includes a magnetic DC connector that ensures your power cable will detach if it experiences excessive strain and helps prevent fraying or weakening of the cables over time. Furthermore, the magnetic DC connector helps guide the plug into the system for a fast and secure connection. When the connection is secure, an LED located at the head of the DC connector will illuminate; an amber light indicates that your portable device is charging, while a green light indicates a full charge. An AC cord is provided with the adapter for maximum cord length, and the included AC wall adapter offers a compact travel solution.

Designed for travel, the adapter features an intelligent design that allows the DC cable to be neatly wound around itself for simple storage. This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It can also power the system when operating without a battery. It is compatible with 15- or 17-inch MacBook Pro
