When the connection is secure an LED located at the head of the DC connector will light; an amber light lets you know that your portable is charging while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length while the AC wall adapter (also provided) gives users 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 if you choose to operate without a battery.
Compatible with MacBook and 13-inch MacBook Pro.
