Questions about this item

How hot does the 85W Mag 2 T-Tip adapter get when it runs all day?

The adapter draws up to 1.5A from a 100-240V supply and delivers 20V at 4.25A, with built-in overcurrent, overvoltage and short-circuit protection that limits heat during continuous use.

What must I already own for the 85W Mag 2 T-Tip charger to work?

A MacBook Pro 13-inch or 15-inch Retina from mid-2012 through 2017, or a MacBook Air 11-inch or 13-inch from the same period, equipped with the MagSafe 2 T-Tip charging port.

Will the 85W Mag 2 T-Tip adapter charge my older MacBook Pro that uses the original MagSafe connector?

No — the adapter uses the MagSafe 2 T-Tip interface, which fits only Mac models from mid-2012 onward such as A1398, A1425 and A1502; earlier MagSafe 1 machines are not compatible.
