Apple 85-Watt MagSafe Power Adapter (for 15- and 17-inch MacBook Pro)
Official Apple product, sold new in blister pack and original box.
The 85-watt MagSafe Power Adapter incorporates a magnetically-coupled DC connector that automatically disconnects the connector if excess voltage is on the cord, thereby extending cable life. In addition, this magnetic connector makes it easy to insert the plug into the system for a quick and stable connection.
When the plug is fully seated, an LED at the top of the DC connector will light up. The orange light indicates that the laptop is charging and the green light indicates that the battery is charged. A power cord is supplied with the adapter to give you maximum cord length. A wall power adapter (also included) gives users an easier to use and more compact tool when on the go.
Designed to be the perfect travel companion, this adapter features an ingenious design that neatly coils the cable for easier storage.
This AC adapter charges the lithium polymer battery whether the system is on, off, or in standby state. It can also power the system if you choose not to use the battery.
Compatible with 15 inch or 17 inch MacBook Pro.
