I like the idea but I don’t like that they make it for Xbox, and also I don’t find useful the parent mode. Parents should be with the kids and teach them what is good and what bad, not limit them with a switch. Anyway, it is up to the parents.
Welcome to Xbox One super battery.
By the way, they don’t say it, but it is obvious that they use a super capacitor instead of a battery. I would say that it is not the kind of thing you will give to very young kids, it is dangerous if you open it and play with it.
