The 45W MagSafe 2 power adapter features a magnetic DC connector that will disconnect if the cord accidentally trips you, keeping your MacBook Air safe. It also helps prevent fraying or weakening of the cables over time. Additionally, the magnetic DC guides the plug into the system for a quick and secure connection. When the connection is secure, an LED located on the head of the DC connector lights up; an amber light tells you that the notebook is charging and a green light tells you that you have a full charge. The AC adapter that comes with the adapter provides maximum cord length, while the AC wall adapter (also included) gives you an easier and more compact way to travel. The adapter is intelligently designed to be the perfect travel companion, allowing the DC cable to wrap around itself for easy cable storage. The power adapter recharges the lithium polymer battery whether the system is off, on, or in sleep mode, and it will also power the system if you choose to work without a battery. Only compatible with MacBook Air models equipped with a MagSafe 2 power port. Model MD592ZE/A Quantity (1) (( Contact only on WhatsApp )) ((Contact only on WhatsApp)) Color: White Condition: New
