The Apple 85W MagSafe Power Adapter for MacBook Air is designed with several features that are both convenient and functional. 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. The AC power cord that attaches to the MagSafe Power Adapter increases your mobility while the laptop is connected to the charger, and Apple’s clever cable storage design makes it an ideal travel partner.
