Got the same problem here - burnt tps61088, same board, same manufacturing date.
Bought on Amazon, explained the issue and I was offered a refund by Anker.
I see that Anker is now selling Soundcore PRO+ models, which look exactly the same.
Now my question is, did Anker address this issue in the PRO+ model and what are the actual differences between the PRO and the PRO+? I don't seem to find any specs.
