Anker has recalled six power bank models in June alone due to issues from 'a single vendor.'
I have a bunch of Ankers, and of course at least one of them was part of this.
Edit/Clarification: Only certain serial numbers are affected. If your model is listed in this, you'll need to enter its serial number in the recall form to see if that specific unit is affected.

Anker Power Bank (10K, 22.5W) — Model A1257
Anker Power Bank (20,000mAh, 22.5W, Built-In USB-C Cable) — Model A1647
