Use an extra adapter for home or work. The Apple 85W MagSafe 2 Power Adapter is made specifically for your MacBook Pro with Retina display. It's held in place magnetically, so if someone should trip over it, the cord disconnects harmlessly and your notebook stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magneticDC 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 maximumcord 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 ifyou choose to operate without a battery.
Compatible with MacBook Pro with Retina display.
