I found a black Anker PowerCore 10000 portable charger this morning around 11:15 am on the sidewalk outside Bayside Marketplace at 401 Biscayne Blvd, Miami, South Florida. It has a short micro-USB charging cable attached, and there’s a small dent on the bottom-right corner plus a red sticker with the initials 'KB' on the back. It looks like it was used recently and still shows about 60% charge. If this belongs to you, message me here and we can meet up near the Bayside entrance to get it back to you.
