Simply put, a charging station in the room of the apparatus (that loses the power to charge items once the apparatus is pulled).
I can also imagine with each charge, there's the possibility ( a configurable %) that the Apparatus goes unstable and shuts down the power to the Dungeon as if it was pulled (which can also integrate with other wonderful mods like "FacilityMeltdown" (Mod by loaforc) and "LethalRadiation" (Mod by gamehog44). The apparatus would of course also still be able to be pulled, carried and sold as usual.
Practical.. Dangerous.. Risk and Reward~
