45W T-Tip charger replaces MacBook Air 11 and 13.3 inch adapters from 2012 to 2017
This 45W T-Tip AC adapter replaces the original charger for MacBook Air 11 inch and 13.3 inch models released between 2012 and 2017. It delivers 14.85V at 3.05A and accepts a universal 100-240V 50-60Hz input. The unit is built for owners of compatible MacBook Air laptops who need a direct power replacement.
The adapter integrates over-current, over-voltage, overload and short-circuit safeguards with auto-recovery behaviour. It carries CE, FCC and RoHS certifications confirming compliance with safety and environmental standards. A fixed T-Tip connector mates with the MacBook Air charging port without requiring an additional cable.
This charger only fits MacBook Air units that use the 45W T-Tip interface, specifically the 11 inch and 13.3 inch models from 2012 through 2017. It will not work with later USB-C MacBook Air models or any device requiring a different connector or wattage. Buyers must verify their exact model number before purchasing.

The adapter delivers 14.85V at 3.05A, giving a total of 45W for compatible MacBook Air models.
It fits 11 and 13.3 inch MacBook Air units from 2012 to 2017, including model codes MD223, MD224, MD231, MD232, MD711, MD712, MD760, MD761, MJVM2, MJVP2, MJVE2, MJVG2, MQD32, MQD42 and MQD52.
Plug the T-Tip connector firmly into the MacBook Air charging port until it clicks, and connect the AC cord to a 100-240V 50-60Hz outlet; the mistake is forcing the tip in upside down, which can damage the port.
