They seem fine to take in checked luggage.
There have been other devices banned for similar reasons, like the Samsung Galaxy Note7: https://www.transportation.gov/briefing-room/dot-bans-all-sa...
If they detect something like that in your luggage, they will kindly ask you to take it in the cabin.
They never cared about CR2032 cells.
I got stopped at security and was shown my luggage. After removing the power bank it was all good, luggage was put onto plane and I was allowed to board.
There are stricter rules however for spare batteries, including power banks. https://www.tsa.gov/travel/security-screening/whatcanibring/...
