How to make one power source power multiple electronics?

[Stormy3D]

Hey, guys. As I said in an earlier post, I know near to nothing about electronics. But I have been learning but I am yet to find out how to make one power source power multiple electronics? (Provided, of course, the power source could provide enough power to those electronics) . The design I am planning is based on this one: http://www.whitearmor.net/forum/topic/39469-howto-super-clean-helmet-electronicsinterior-build/, with some other components such as Ukwarth's setup. The power source (12v) I plan to use is this: https://www.amazon.com/gp/product/B00VE7HBMS . The fans I currently have (12v) are these: https://www.amazon.com/gp/product/B015S5XFJE . Again, I want to know how I could modify the power source to power both of these fans, and possibly, more systems. Thanks!

This is simple if you understand electronic theory, as mentioned in your other thread. Once you understand this the sky is the limit. The key point here is what exactly you plan to run, the voltage input, amps the items draw, how/if the items will interact with each other, etc. If you give us an idea what exactly you're going to run we can better assist you. So far you mentioned fans, anything else? Note, the battery back you've mentioned is quite large and will only fit in your chest plate or elsewhere so you'll have to run a power cord into your helmet.

I plan to just use fans so far, thanks for the info!

My personally recommendation would be this: Unless you NEED 12v power for some reason, ditch those 12v fans (they're cheap so no big loss) and bulky AA battery pack, and get some 5V fans.  Then you can use a cheap 5V USB mobile phone power bank to run your fans.  A very small and inexpensive rechargeable battery bank will run your fans for 8+ hours, easily.

 

Pretty good writeup in this thread:

Smart. I think I'm going to try that!
