Black Anker PowerCore Slim 10000 with KF sticker

I lost my black Anker PowerCore Slim 10000 portable charger yesterday around 3pm near Riverfront Park along Riverfront Drive, just past the Fort Smith Public Library's south entrance. It's a slim, about 5 inches long by 2 inches wide, black plastic with a slightly worn bottom-left corner. On the back there's a bright orange sticker with the initials KF, plus a tiny dent on the top edge from a drop last week. It really means a lot to me—it's sentimental because it was a gift from my sister, and I rely on it on my Fort Smith outings. If you found it, I’d really appreciate getting it back.
