The Macbook 85W Replacement MagSafe 1 L-Shaped TIP 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.Compatible only with MacBook Air
featuring MagSafe 1 power port
