Apple Caricabatterie MagSafe 2 85W power adapter MD506Z/A

The 85W MagSafe 2 power adapter has a magnetic DC connector that detaches without damage if someone trips over the cable, so your MacBook Pro doesn't take flight.
It also prevents cables from deteriorating over time, makes it easier to plug into the computer, and the connection is safer.
Once connected, the LED on the connector lights up: an amber light indicates that the notebook is charging; a green light indicates that the charge is complete. An AC cord is also provided for easier work, while with the AC plug (always supplied) the power supply becomes more convenient and compact for when you are on the go.
Designed to be the perfect travel companion, the power supply has a clever design to neatly wrap the DC cable for easy storage.
This power supply charges the lithium polymer battery while the computer is off or asleep, or powers it if you decide to use it without a battery.
