In order to get 7.5W charging on the go, update your MagSafe Battery Pack to the latest firmware. The firmware update begins automatically after you attach your battery pack to your iPhone. The firmware update can take about one week.
While taking a week to update is quite long, there is a faster way to update.
To update the firmware using a Mac or iPad, plug one end of a Lightning to USB cable into the Lightning connector on your battery pack, and the other end into your Mac or iPad. The firmware update will take about 5 minutes.
The MagSafe Battery Pack is compatible with the iPhone 12 and 13 lineups. Released in July of 2021, it hasn’t been one of Apple’s most well-liked accessories.
