Palm-sized Anker power bank

I lost my Anker power bank, palm-sized and charcoal gray with a bright orange silicone case, yesterday around 3pm near the Walmart on Buffalo Gap Road in Abilene. It's about the size of a standard smartphone and has a small dent on the bottom-right corner, plus a tiny blue sticker with my initials 'A.J.' on the back. The case started peeling a bit where the charging port is, so you can see the silver metal underneath. It’s important to me because it was a gift from my sister and I really need it back before a trip this weekend.
