After being late to the party of becoming aware that ledger pooped in everyone's cornflakes, I've decided to go with Trezor Safe 5.  I was watching setup videos on youtube and I am concerned about having to connect to a computer BEFORE it releases the seed phrase.

Is this the case?  Can it not give out seed phrase with just a power source?

One of the videos appeared to be someone from the Trezor company, so I would think if it were possible to retrieve seed phrase without computer, that would have been mentioned, but wanted to be sure.

If it is possible, you would think it woukd have been stated because to me it defeats the whole purpose of an air gap.
