Andrea Rossi has announced on the Journal of Nuclear Physics an upgrade to the E-Cat SKLed that he plans to introduce in November. The SKLed will not only be able to be powered from a regular AC socket, but will also be able to powered by a 12 V DC power source from a battery.

Dan Galburt (second answer of today):
Our team worked today on your suggestion: all the the Ecat SKLed will be able to be powered either with their plug connected to the grid at 110-240 V, 50-60 Hz, OR with any 12 V battery, and it will be the undisputed lamp with the longest autonomy of the world, at parity of battery Ah.
You gave us a great idea. We got it. The DC connection will poke out from the rear face of the Ecat’s body.
He explained to me that “The 2 cables (red and black) will be terminalized on the back face of the body.”
