Maybe I am too paranoid from people “just asking questions” all the time but actually pushing something they are too afraid to say out loud, but to me it seemed like exactly that behaviour. If he was actually interested in providing information on that “debate” he could have talked about it with the actual experts in his video but he just leaves it as an open question. To my understanding this openness is a strong misrepresentation of the scientific consensus because this exact motor has been used by creationist for a while and their arguments have been debunked by scientist for years.
I guess they might be referring to this.
TLDR: The RPi5 draws up to 5A at 5V which is USB-C PD conform, but it is quite an uncommon combination, so it’s hard to find third party power supplies.
