Use an extra adapter for home or work. Apple's new, innovative AC adapter is made specifically for your new MacBook Pro.

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 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 is charging, while a green
light tells you that you have a full charge. An AC cord is provided with the
adapter for maximum cord length, while the AC wall adapter (also provided) 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.
Compatible with MacBook Pro.
