The MagSafe 45W Charger for Apple Mobiles features a magnetic DC connector which ensures that the power supply cable is disconnected in the event of undue strain, and helps prevent cables from getting frayed or weakened over time. In addition, magnetic direct current helps guide the plug in the system for a fast and secure connection.
In the case of a secure connection, the LED light at the end of the DC connection lights up, the amber light indicates that the mobile is charging, and the green light indicates that the charging is complete. An AC cord comes with the charger for maximum cord length, while an AC wall charger (also available) offers a smaller size for increased portability for users.
Designed to be the perfect travel companion, the adapter features a clever design that allows the DC cable to loop tightly around itself for easy cable storage.
This power charger recharges the Lithium Polymer battery while the system is turned off, on, or in sleep mode. It can also power the system if you choose to run without battery.
