·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 Pro 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.
·Compatible only with MacBook Air featuring MagSafe 2 power port
