MagSafe 2 Compatibility Guide

 45W MagSafe 2 Charger:

• MacBook Air (11-inch, Mid 2012 – 2017)

• MacBook Air (13-inch, Mid 2012 – 2017)

 60W MagSafe 2 Charger:

• MacBook Pro Retina (13-inch, 2012 – 2015)

 85W MagSafe 2 Charger:

• MacBook Pro Retina (15-inch, 2012 – 2015)

Important: Make sure to check your specific MacBook model for compatibility with the correct wattage. For example, a 60W charger works well with the 13-inch MacBook Pro Retina, but using an 85W charger on a 13-inch model won’t damage it, though the 85W model is overkill. However, using a lower-wattage charger (e.g., 45W) on a 15-inch MacBook Pro Retina could result in slow charging or insufficient power.
