Blue Anker PowerCore 10000 power bank

Yesterday around 3pm I realized my blue Anker PowerCore 10000 USB-C power bank was missing after a quick coffee run and a detour through the Tesco Express on Hills Road in Cambridge, East Anglia. It's a compact, matte blue rectangle about the size of a small paperback, with a white Anker logo on the front. There’s a tiny red sticker with the initials 'KJ' on the side and a small dent on the bottom edge from a fall last week. I rely on it every day to keep my phone charged during long train commutes, and it has sentimental value because it was a gift from my sister. If someone found it, I’d be really grateful to have it back.
