Black Anker power bank with red sticker

I lost my black Anker 10,000mAh portable charger yesterday around 3pm near the entrance of the Butte-Silver Bow Public Library on Main Street. It's about the size of a deck of cards, has a slightly worn black finish, and the top edge sports a small red sticker I slapped on for easy finding. It lives in a blue silicone sleeve and there's a tiny dent on the bottom-right corner from a drop last week. This charger means a lot to me—it powers my work phone and keeps my day running, and I really need it back if anyone found it.
