I have a couple of these great graphene batteries that work just as advertised.
5 amp hour, 60 watts, that fully recharges from empty in 17 - 18 minutes.

That is very cool. I’ll probably look into it next time I need a power bank. I have several right now. One is 30k mAh. Once that one finally gives up the ghost, it will be time for another.
