The Apple 45W MagSafe 2 Power Adapter for MacBook Air from Apple with its "T Style" form factor provides for easy convenient charging. It features a magnetic DC connector, which easily unplugs when excessive strain is applied to the cable. This feature also helps guide the cable quickly into its port and limits the wear and stress that other adapters face. An LED indicator on top of the adapter cable illuminates orange when the battery is charging and turns green when the charge is complete.
