Energy, power, current, they all are part of the fuse vs no fuse discussion. You cannot separate them. As I said already, I am the only one present here who has experience with both the fancy fuse and no fuse cases. When you use low power components as I do, just in case no one picked up on it, battery-powered CD player, there is no need for a fuse, any fuse, there isn’t even a place to put a fuse if you wanted to. That’s the no fuse case. As opposed to the fuse bypass case which is yet another case.
A big shout out to the guys who got the Nobel Prize for Chemistry for inventing the Lithium battery last week. 🤡
