Gray Anker 20K power bank with rocket sticker

I lost my gray Anker 20,000mAh power bank yesterday around 3pm. It's a compact, matte gray rectangle about the size of a paperback, with a dent on the top-right corner and a bright orange rocket sticker on the back. I think I last had it in the parking lot behind Riverside Market on Main Street, near the Northern Panhandle Library in Wheeling, before I walked toward the Market Street bus stop. It powers my daily setup and is essential for keeping my medical alert device charged, so it’s really important I get it back. If you found it, please drop me a message—I’d be forever grateful.
