Black Anker PowerCore 20k power bank with blue strap

I lost my black Anker PowerCore 20,000 mAh external battery yesterday around 3pm near the Moscow Food Co-op on Main Street in Moscow, ID. It's a matte black rectangle, about the size of a paperback, with a blue silicone strap still looped through the corner. There's a white sticker on the back with the initials 'AP' and a tiny dent on the bottom edge from a drop last week. It powers my phone during long days on campus, and with finals coming up I really need it back. If anyone found it, email me at [email protected] and we can figure out how to swap it back.
