Lost black Anker portable phone charger left at a coffee shop near downtown Iowa City.

I accidentally left my portable phone charger at a coffee shop near downtown Iowa City. I remember using it to charge my phone while sitting at a table by the window, but when I got up to leave, I must have forgotten it. It's a black Anker brand charger, small and rectangular, and has a couple of scratches on it. If anyone has seen it, I would really appreciate getting it back!
