The 60 W Magsafe 2 Current Adapter has a magnetic CC connector for the cable to turn off and the MacBook Pro does not fall into if someone stumbles on it. It also helps prevent cables wear over time. In addition, the CC magnetic connector helps connect the laptop plug and establish a quick and secure connection. When the connection is safe, the LED situated on the CC connector head lights up. The amber light indicates that the notebook is loading and the green light warns that the battery is charged. The CA cable is supplied with the adapter for a maximum cable length, while the AC power supply (also included) allows you to travel with less weight. Designed to be the perfect travel companion, the transformer has an intelligent design that allows you to curl the CC cable for easier storage. Compatible with MacBook Pro models with 13-inch retina screen released between 2012 and 2015.
