85 Watt MagSafe Power Adapter for MacBook Pro 13 15 and 17 Inch Series Laptops

The 85 Watt MagSafe Power Adapter features a magnetic DC connector that ensures your power cable will disconnect if it experiences undue strain and helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC connector helps guide the plug into the system for a quick and secure connection. When the connection is secure, an LED located at the head of the DC connector will light; an amber light lets you know that your portable device is charging, while a green light tells you that you have a full charge. The AC wall adapter gives users an even easier and more compact way to travel. Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage. This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
