Portable power for cold cathode?

[Mega Gigan]

I'm planning on using some cold cathode tubs for a costume I'm developing. My issue is that I'm not sure how to make it portable.

Most of these run on a Molex connector for computers, which I think is about 12 volts. There are specific cold cathode units I wish to use. Would anyone be able to suggest something (lightweight perhaps?)

this is the cold cathode I'm looking to use...

You could try battery packs for cordless tools, those are fairly powerful, and easy to swap out and charge.

Saw a good suggestion in an instructable for this:

if I had it to do over again, I'd have got to the store and bought one of those little 12 volt batteries they use in wireless doorbells, or just used a stack of button cells. Sure, it wouldn't last as long, but it would be much lighter and smaller.

Hope that helps.

When I need portable 12VDC I use a 9V battery wired in series to a battery pack for 2 AA batteries. I used it to power an EL cord I had attached to my clothing a couple times. The pack is pretty light weight and fits into most pockets.

Airsoft or R/C car packs are good if you want a bit more lifespan from them
