It's not just about the heat output, although that does make a difference (cooking edit: thin* steak on a weak electric stove is hell). There is no amount of heat that will penetrate the inner part of the chicken while not burning the outside cooking only 3-4 minutes per side (unless you reduce the thickness of the chicken via butterflying, as another commenter pointed out, but you don't want to always to do that).
