Product Description :
The 45-Watt MagSafe Power Adapter for MacBook Air 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.
Redesigned specifically for MacBook Air,
the adapter is the perfect traveling companion.
It 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 only with MacBook Air with MagSafe Power Port.
