Can such a small thing really supply 12V?

I have these batt's, these really supply 12V but these don't have much juice !
Have you thought any new ideas ?

Cool.

If I buy a pack of these:

5pcs mini 650nm 5mW 5V Laser Dot Diode Module | eBay

What kind of voltage would be needed? They state 5V as operating current, but I want to power all 5 of them at the same time in one single circuit, what battery/ies would work?

And also, if I buy a battery holder which has a negative and positive wire, would I wire all 5 positive wires of the 5 diodes to the positive wire of the holder? So 5 wires are attached on that one?

Thanks!

You will need 25V to power the modules !
You can use 2x A23 batteries.

you could just not do it then say you have an invisibility cloak
