Previously, the MagSafe Battery Pack only released 5W, and following users have automatically updated the firmware via OTA when the MagSafe Battery Pack is attached to an iPhone with MagSafe, it’s possible. It will be able to charge the iPhone at 7.5W, instead of being limited to 5W.
Users can check the version by going to Settings > General > About > MagSafe Battery Pack. If it’s version 2.7.b.0, it can be charged at 7.5W.
