I've never had any issues with brand name, not dollar store power banks and I've been using them for more than a decade. I'd totally expect a $5 pink power bank from a alphabet amazon seller to be an issue, but anything modern and reasonable like Anker are very unlikely to cause you any issues. Balancing, protection are very much solved issues at this point for the cell chemistries we use.
If LiPo was the issue, using LiFePo4 or LTO cells for planes would be a totally reasonable alternative too. LTO cells are so safe the manufacturer of them has videos on youtube of them hammering nails into the cells, cutting them with a saw, and crushing them with a press and they don't really care.
Not really, even Anker recalled a huge number of power banks last year: https://www.cpsc.gov/Recalls/2025/Anker-Power-Banks-Recalled...
That's a bit surprising to me, wonder what the root cause of that was. It seems to be shared across multiple products at once so maybe they had a bad batch of cells?

You bring dollar store power banks onto airplanes?
