85W T-Tip AC Adapter for MacBook Pro/Air 13/15″

This 85W T-Tip AC adapter replaces the original charger for MacBook Pro and MacBook Air models with 13-inch or 15-inch Retina displays released between 2012 and 2017. It accepts AC input from 100-240V at 50-60Hz and delivers DC output at 18.5V and 4.6A. The unit is a second-generation power adapter designed as a direct replacement for part numbers such as A1424.

LED charging status indicator

An integrated LED provides immediate visual feedback on the battery state. An amber light indicates the notebook is actively charging, while a green light confirms a full charge. This feature allows users to verify the connection and charging progress at a glance without opening the laptop lid or checking the on-screen menu.

T-Tip connector compatibility

The T-Tip magnetic connector fits the specific port used on MacBook Pro 15-inch (A1398) models from 2012-2015 and MacBook Pro 13-inch (A1425, A1502) and MacBook Air 13-inch models after 2012. It is not compatible with earlier L-Tip or later USB-C charging ports found on different model years.

Questions about this item

Does the 85 W T-tip adapter have any user-replaceable parts that wear out?

The adapter is a sealed unit with no user-replaceable parts. If the cable frays or the connector pins bend, the whole unit must be replaced.

What limits continuous output when the adapter powers a 15-inch MacBook Pro at 85 W for hours?

The 18.5 V / 4.6 A output rating is the hard limit; sustained loads at that level will cause the internal protection to throttle or shut down if thermal headroom is exceeded.

How much heat and noise does the brick produce when left plugged in all day?

The brick runs silently with no fan. Under full 85 W load it becomes warm to the touch, and the amber or green LED indicates charging status.
