Apple magnetic Charger. The  Magnetic Chargerfeatures a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your Apple stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection. When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your Apple 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 you an even easier and more compact way to travel. 

Designed to be the perfect traveling companion, the Charger has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage. Compatible with all Apple watch models

Apple does not provide a power adapter with the charger, requiring users to make use of the USB compatible option. ‌MagSafe‌ charger at this time.
