My guess is it’s similar to the electric motors they put in cars vs industrial motors… they can both put out X amount of power but the industrial ones (or in this case the laptop power) can do it continuously without overheating while the other can only output “up to” that power rating for a short time without burning up.
In this case though, the laptop power probably also outputs a higher voltage as well.
They probably won’t get rid of elections… they’ll just have sham elections like Russia has to give the impression of “legitimacy” but I guarantee they’ll be heavily rigged in their favor.
