MagSafe Battery Pack

The MagSafe Battery Pack was designed by Apple to provide more portable power to iPhone 12 or later models that support wireless MagSafe charging.

History
The MagSafe Battery Pack was released for sale on July 13, 2021. It is the first Apple product to support reverse-charging, where it can charge or be charged by a supported iPhone.

Usage
The MagSafe Battery Pack attaches in place with magnets. However, it cannot be used simultaneously with a MagSafe Charger. When an supported iPhone is at least 80% charged through the Lightning port, it will begin charging the MagSafe Battery Pack. It requires iOS 14.7 or later and appears in Today View and the Home Screen as a separate device being charged.
