Wow, yeah, your gunna need some sort of inverter. Cold cathodes work at roughly 400volts. Its kinda tricky to find the right inverter for ccfls, it might just be easier to buy new ones. Only a couple bucks on newegg. Find an old computer powersupply to run them off of, that 5volt phone charger isnt enough, youll need at least 12 volt. But then you should be set

Well jake it sounds like you think you know what your doing. If you think that a 5 volt (I think about 10 watt) power supply will power 5 cold cathodes then I think you need to do some more looking.
