Apple announced its MagSafe Battery Pack for the iPhone 12 series yesterday. While the accessory charges your iPhone 12 wirelessly at 5W, there is a secret feature that you might not know of. We have been hearing for a long time that the iPhone 12 will feature reverse wireless charging capabilities and it looks like the new accessory just unlocked it. You read that correctly, the iPhone 12 and iPhone 12 Pro models can reverse wirelessly charge the new MagSafe Battery Pack.

This is the very first instance where an iPhone can charge another device wirelessly. It works quite seamlessly with the MagSafe Battery Pack attached to the iPhone 12 series. Charging your iPhone 12 with a Lightning cable will wirelessly charge Battery Pack as well. The power will travel through the iPhone and charge the new Battery Pack through MagSafe.
