CPU Fan Wiring

I have 4 computer fans I am trying to wire into an extension cord to plug into the wall. Do I need a voltage convertor inbetween the fans and the wall plug. Here is a link for the fans:Newegg.com - ARCTIC COOLING ARCTIC FAN 3 80mm Case Fan - Case Fans

Use a cellphone charger with matching specifications. Easiest way to do it.

would one cell phone charger be enough to wire 4 computer fans into one charger?

If it is the right matching specifications.. I would thank so but not sure on that
would have to test it out .

One charger wouldnt be enough for 4 fans.

if its anything over a 12 volt output its should work for atleast 3 i have a 2 12 v fans and they are running strong off a old 12v output Nintendo cord

How strong? I doubt its close to full capacity

So strong they are to loud

woah, be careful with those monsters
