Black Anker PowerCore 10000 charger

Yesterday around 3pm I realized my black Anker PowerCore 10000 portable charger was missing near the Mount Baker Theatre area on Cornwall Ave, outside the entrance by the bus stop. It's a compact black rectangle, palm-sized, with the silver Anker logo on the front and a small dent on the bottom-right corner. I also stuck a tiny blue whale sticker on the back so I could tell it from others. It has sentimental value—my sister gave it to me for solo trips—and I’d really appreciate getting it back so I can stay powered up when I’m out and about.
