45W MagSafe 2 T-Tip Adapter for MacBook Air

This 45W MagSafe 2 power adapter replaces the original Apple charger for MacBook Air 11-inch and 13-inch models released between 2012 and 2017. It delivers 14.85V at 3.05A through a magnetic T-tip connector that aligns automatically. The unit accepts 100-240V AC input at 1.5A for worldwide use. It suits owners of compatible MacBook Air units needing a direct replacement power supply.

Sustained load behaviour and protection

The adapter provides a continuous 45W output with built-in overload, overcurrent, overcharge, overvoltage and short-circuit protection. The durable tinned copper core cable is rated for approximately 15000 bending cycles to resist fatigue during daily use. An amber LED indicates active charging while a green LED shows a full charge, at which point power is automatically cut off. The brick measures 2.57in by 2.57in by 1.12in and weighs 0.2 kilograms.

Installation notes and common issues

The magnetic T-shape connector snaps into the MacBook Air charging port for tool-free installation; the foldable AC plug reduces packing volume. Ensure the MacBook Air model number matches the supported list including MD223, MD224, MD231, MD232, MD711, MD712, MD760, MD761, MJVM2, MJVP2, MJVE2, MJVG2, MQD32, MQD42, MQD52, MMGF2 and MMGG2. This adapter is not for MacBook Pro models or newer MacBook Air units that use USB-C charging.

Will this 45W T-Tip adapter safely charge an older MacBook Air that originally shipped with a 45W MagSafe 2 unit?
