Terribly sorry, I got sidetracked off on a business trip (that I'm still on for a few more weeks...)
I turned off power consumption because I was using the mod in a base previously which didn't have it, and suddenly having thousands of chests requiring it was a bit problematic. Mostly it's just a "I got used to it that way" sort of thing. I guess you could consider the power a balancing factor, but half the setups where I use these chests in I'll have ten thousand times as much power and requiring wiring just makes everything more inconvenient for not much real benefit. The chests are, in their own way, cheaty as hell, so I don't see adding challenge back to it with power as making a ton of sense.
Notably I use it in one of my Pyanodon playthroughs where I want to do things other than "endless logistics" and a lot of machines in there will run off things like gas or fuel instead of electricity, so in that one I have a decent number of outposts scattered throughout the world which are whole kilometers away from the nearest power. I could set up some solar just to run the chests or something, but ultimately the addition of a power requirement just doesn't add anything to the fun for me here.
