Replacement 85W T-Tip charger for 2012-2017 MacBooks

This 85W replacement charger is built for MacBook Pro 13, 15 and 17 inch models alongside MacBook Air 13 and 15 inch units sold between 2012 and 2017. It uses the second-generation magnetic T-Tip connector that seats quickly and releases safely under strain. The unit accepts AC 100-240V at 50-60Hz and delivers DC 20V at 4.25A.

Second-generation magnetic T-Tip connector

The defining specification is the T-Tip magnetic interface used on Mac notebooks from 2012 through 2017. It is not compatible with earlier L-shape MagSafe 1 ports or later USB-C and MagSafe 3 connections. Buyers must confirm their machine uses the T-Tip style before ordering.

85W output covers Pro

The 85W rating comfortably powers every listed Pro 13, 15 and 17 inch model and Air 13 and 15 inch model released between 2012 and 2017. It will not suit machines outside that window or devices that require higher wattage or a different connector type.

Questions about this item

What does the 85 W output actually deliver when the charger is plugged into a MacBook?

It supplies 20 V at 4.25 A, matching the power draw of 13, 15 and 17 inch MacBook Pro models and 13 and 15 inch MacBook Air models from 2012 to 2017.

How does the T-Tip magnetic connector affect the charging connection?

The second-generation T-Tip snaps on magnetically, guides the plug into the port, and releases safely if the cable is pulled, preventing strain on the laptop.

What physical space does the adapter need on a desk or in a bag?

The brick is a compact T-sized unit with a standard AC cord for 100–240 V input, so it fits easily alongside other accessories.
