Haven't looked at power draw yet, to determine if 18awg is enough to supply power to both. I know the power cords supplied with them are 18awg, but that's 18awg for each one. Odd though, that it says that it's got a power draw of 120v 10Amp, but that would require 16awg wire I thought... I'll have to get my kill-a-watt out and give it a look I think...
