It's easier to deal if it's in carry on bag. This is why batteries are forbidden in checked luggage. Once it all burns the airplane has got to land asap and it's an emergency.
My checked luggage did not pass xray multiple times because they detected powerbanks. I had to come back and take it out. However it also did pass xray a couple times with powerbanks so it's not a reliable system.
Alternatively, I checked 3-4 20k mAh powerbanks in my luggage on my flight to Utah and it never got flagged or detected.
like yes I pointed out it doesn't always work. sometimes I don't even know if anybody is watching the screen
