A hidden wire at 10 KV would need to carry only 50 mA. That's "small".
A battery would need to supply (say, conservatively) 500 W for 116 hours, or 200 MJ. Lithium batteries are about 2 MJ/Kg, so that's 100 Kg of battery. I agree that's unlikely but don;t have enough information to make the call.

A power meter looking at wall power is blind to any internal power source in the box that directly supplies the device with additional power. What sort of internal power source? A generator? That would noisy and obvious. A battery? That would run out before 5 days elapse. Or, if Rossi has developed such a battery, it is an important discovery in its own right. A hidden wire? It would have to be a fairly large wire, to carry 500 to 800 W. They would see it. Do you have anything else in mind? - Jed
