45 W Mag2 charger for MacBook Air 2012-2017

This 45 W power adapter uses the magnetic Mag2 T-tip connector to charge 11-inch and 13-inch MacBook Air models released from 2012 through 2017. It accepts a universal AC input of 100-240 V at 50-60 Hz and delivers 14.85 V at 3.05 A for direct compatibility with the original supply.

Thermals, noise and power draw

The unit operates from a standard 1.5 A mains input and provides a regulated 45 W output without active cooling, so it runs silently in normal use. Built-in protection against over-current, over-voltage, overheating and short circuits helps maintain stable temperatures while safeguarding the connected laptop.

Magnetic connector and daily use

The Mag2 T-tip snaps on magnetically, reducing strain on the port and allowing quick attachment in low light. CE certification confirms compliance with European safety standards, and the compact brick is designed for portable use with the listed MacBook Air models. It does not fit newer USB-C MacBooks or older MagSafe 1 systems.

Questions about this item

How do I install the Chopmate 45W Mag2 T-Tip charger and what is the step people often get wrong?

Connect the AC plug to a 100-240V 50-60Hz outlet then attach the magnetic T-Tip to the MacBook Air charging port; the common mistake is forcing the connector instead of letting the magnet align and seat it gently.

What maintenance or replacement will this charger need later?

The detachable AC cord can be swapped if the plug or cable frays; the brick itself has no user-serviceable parts so replace the whole unit if output drops below 14.85V 3.05A or the magnetic tip becomes loose.

What limit appears first during sustained use of this 45W adapter?

Continuous full-load operation at 45W will hit the thermal protection circuit first causing the charger to throttle or shut down until it cools.
