85W MagSafe 2 T-Tip Adapter

This new 85W AC adapter delivers 20V at 4.25A through a MagSafe 2 T-tip connector. It is built for MacBook Pro 13, 15 and 17 inch models from 2012 to 2015 and MacBook Air 13 and 15 inch models from the same period. The unit accepts AC input from 100 to 240V at 50 to 60Hz.

Sustained 85W Output Stability

The adapter maintains its rated 85W output continuously while the laptop charges and runs demanding tasks. An amber LED indicates active charging and a green LED shows a full battery. The magnetic T-tip releases safely if the cord is pulled, preventing stress on the port.

Verify MagSafe 2 Port Before Ordering

This charger only fits devices equipped with the second-generation MagSafe 2 T-tip port used between 2012 and 2017. It will not connect to the original L-shaped MagSafe 1 port found on earlier MacBooks or to USB-C power ports on later models. Confirm your model number matches the listed compatibilities such as A1398, A1424, A1465 or A1466.

Questions about this item

How much heat or noise does the 85W adapter produce when powering a MacBook Pro 15-inch all day?

The adapter runs silently with no fan; it may become warm during continuous 20V 4.25A output, which is normal for a compact 85W supply.

Which AC cable must I already own for this adapter to work with UK mains?

You need a standard IEC C7 figure-8 mains lead; the brick accepts 100-240V 50-60Hz input so any compatible C7 cord fits.

Will the T-tip connector fit my Mid-2012 MacBook Pro 13-inch (A1425) alongside the original 60W unit?

Yes — the MagSafe 2 T-tip matches the A1425 port exactly; the 85W brick simply provides more headroom than the 60W original.
