Power 3V EL wire inverter with DC adapter
Actually the answer was easy, I thought I tried it but trying again gave different results.

I just put two of the things in series and it seems to work. It draws 150mA but I don't think it is so much of a problem, the circuits seem to be functioning fine. I am assuming putting a 3V/110mA=27ohm resistor in series would also work, but I don't have one laying around to test this.
