85W MagSafe 2 T-Tip Adapter

The E-buy 85W MagSafe 2 AC adapter replaces the original Apple A1424 charger for 15-inch MacBook Pro Retina models from 2012 to 2014. It delivers 18.5 volts at 4.6 amps through the magnetic T-tip connector. The package includes the power brick and a detachable duck-head plug for immediate use.

Input Range and Connector Limits

The unit accepts 100 to 240 volts at 50 to 60 hertz, making it compatible with mains supplies worldwide when paired with the correct duck head. The MagSafe 2 interface fits only MacBook Pro Retina models that lack an optical drive; it will not connect to the earlier MagSafe 1 port used on machines that have a CD-ROM drive.

85W Output for 15-Inch Retina

Rated at 85 watts, the adapter comfortably powers the 15-inch Retina MacBook Pro while charging its battery under normal workloads. It is not designed for larger or higher-draw systems and will not supply sufficient power for devices that require a greater wattage rating.

Questions about this item

Should I pick the 85W or the 80W rating on this A1424 adapter?

The unit is specified as 85W at 18.5V and 4.6A; the 80W figure is a secondary label, so use the 85W rating for compatibility.

What does 85W at 18.5V mean when the charger is plugged into my MacBook Pro?

It delivers up to 4.6 amps at 18.5 volts, enough to run a 15-inch Retina MacBook Pro and charge its battery simultaneously.

How does the MagSafe 2 T-tip interface limit what this adapter can power?

The T-shaped MagSafe 2 connector fits only 2012–2014 15-inch Retina MacBook Pro models, so it will not attach to older MagSafe or newer USB-C Macs.
