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.‎
