I don't understand your comment about a dictionary. I referred to the standard definition of power - see (e.g.) http://science.howstuffworks.c... if your recollection is rusty.
As I was posting on Slashdot, I didn't think it was necessary to explain why the extract I quoted is confusing (and confused).
"...can boost 300 to 400 millivolts power to 3 to 5 volts".
Calling millivolts "power" is sloppy at best, but the real strangeness is the idea of boosting "300 to 400 millivolts power to 3 to 5 volts". Given that you can increase the voltage by a factor of 10 or so, one would normally expect that to be accompanied by a corresponding drop in current to keep the power constant. After all, you can't just pluck increased power out of nowhere by changing voltage.
And, of course, you can have a potential difference of millions of volts with no power flowing at all.
