About this item 

• The 85W MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the lead 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 lead is provided with the adapter for maximum lead length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel. 
• Designed to be the perfect travelling 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. 
• Compatibility: MacBook Pro (Retina, 15-inch, Mid 2012–2015)
