Apple 85W MagSafe 2 Power Adapter (for MacBook Pro with Retina display)

The 85-Watt A1424 MagSafe 2 Power Adapter from Apple offers a clever design to be the easiest commute charging companion by winding around itself for easy storage. The magnetic DC connector helps guide the plug into your device for a quick and safe connection. It also will disconnect if it experiences any strain, preventing the weakening of the cable through the years.
The 85W MagSafe 2 Power Adapter features a magnetic DC connector so if someone must go back and forth over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also helps prevent fraying or weakening of the cables through the years. In addition, the magnetic DC helps guide the plug into the system for a quick and safe connection.
When the connection is safe, an LED located at the head of the DC connector lights up; an amber light means that you can know that your notebook is charging, even as a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, even as the AC wall adapter (also provided) will give you an even easier and more compact way to commute.
Designed to be the easiest 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 even as the system is off, on, or in sleep mode. It also powers the system if you select to operate without a battery.
Compatible with MacBook Pro with Retina display
