As fine as I have been with going out more often to jump the transformers, I actually agree there should be an option to disable power depletion or having some module upgrades that steadily improve transformer duration.
It isn't so bad when playing on easier difficulties in the first half of the demo. However, as soon as the warning drone drops, I find myself having to save, quit, and return at the 8AM mark to get "those things" to actually despawn, and it's pretty annoying.
