Getting ready to head back to US tomorrow from Madrid, and we have a camera whose batteries are dead, and we forgot to bring the charger with us (so not able to charge batteries)

News is showing that TSA is preventing anyone from BOARDING who has an electronics device that won't turn on, but nothing on TSA website that I have seen.

Question: Has anyone flown back from an EU country to the USA in the past few days, and noticed any unusual security screening?

I assume this is only for carry on luggage, but you never know, I guess it's possible they could do a pre-check in screening like they do in some airports?

Would be nice if TSA showed something on their site giving some additional details on this.
