Blue Anker PowerCore 20k power bank with case

I lost my blue Anker PowerCore 20,000mAh power bank yesterday around 3pm. It's in a gray silicone case, with a tiny dent on the bottom corner and a sticker with my initials 'PP' on the back. I last had it in the parking garage behind Brickell City Centre on South Miami Avenue, near the valet drop-off. This little device is practical for work trips and it has sentimental value because it’s traveled with me through many late shifts. If someone found it, I’d really appreciate getting it back.
