Guys I really appreciate the responses to what I hope never happens to any of us. I have spent almost all of my "bitcoin life" for the past ten years on a laptop. In the past year I upgraded to a high end desktop but it doesn't have a battery like my laptops did. I was picturing clicking SEND on a Trezor, after reviewing the transaction, addresses, etc.... are all good to go ---- BUT then at that instant the power goes dark!
I only use HD wallets or T Suite for BTC movements. Mainly Electrum with my Trezors. As I suspected it appears even in that instance that I would eventually be whole, if not instantly upon power return. I don't know what makes me think of such things, but in reality it could happen!! Thanks for the consideration of my question!!
If i understood you correctly, i guess you're talking about hypothetical scenario where electricity outage affect your home/apartment where you use Trezor Model T. In that case, the transaction probably won't be broadcasted since it may take few hundred millseconds or more for Trezor Model T to sign your transaction and other node/server receive your signed transaction.
