Apple MagSafe Battery Pack (white), snaps on iPhone 12 and up

Apple MagSafe Battery Pack, white, the original one that clips to the back of iPhone 12 and newer. I used it for about a year for long days in class and it still gives my iPhone 13 roughly one full charge before it runs down. Magnets are still strong and there is slight discolouration on the white plastic from being in a bag. I have two of them. Pickup at El-Kanemi Hall, and I can bring it to Faculty of Arts if that is closer to you.
