Apple MagSafe Battery Pack (MJWY3ZM/A)

You can easily attach the External MagSafe Battery. Compact and intuitive, it makes charging on the go easy. And it has perfectly aligned magnets that attach it to iPhone 12 or iPhone 12 Pro for safe and reliable wireless charging. The MagSafe External Battery charges even faster when you pair it with a 27W charger or faster—like the one on the MacBook. And when you need a wireless charger, just connect it with a Lightning cable for up to 15W wireless charging.
