The 45W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it‎,‎ the cord disconnects harmlessly and your MacBook Air stays put safely‎.‎ It also 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 lights up‎;‎ an amber light lets you know that your notebook 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 you 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.‎
