Apple MacBook Pro MagSafe Power Adapter 85W (MC556Z/B)

Suitable for MacBook Pro 15 inches and 17 inches (2009 to mid 2012) You can use the Apple Portable MagSafe adapter of 85 watts with your MacBook Pro 15 inches or 17 inches. The adapter is fitted with a useful MagSafe connector. A magnetic DC connector ensures the power cord will disconnect if there's too much tension on it. This also helps prevent the power cable from unraveling or eroding over time. The magnetic DC plug also allows you to plug the connector in correctly, so you'll quickly have a good connection. Once it's securely connected, the LED light on the head of the DC connector turns on. The orange light indicates that the portable device is being charged, and a green light indicates it's fully charged. A power adapter cable is included with the adapter for a maximum cable length. This is an original Apple accessory.
