Yup, and at a much lower current than EL.

EL runs at a low voltage, and higher current.

The reason why EL inverters are larger than CCFL, is the frequency. EL frequencies are anywhere from 400hz to 800hz or so. while CCFL runs well above 18khz. maybe even 20 to 30khz. 

Easiest EL inverter is taking an old wall transformer, you know, the old 120v to 12v or 9v, and use it in reverse with a 555 timer and switching transistor.
