Can anyone explain to me how to hook up my 3 computer fans to a regular outlet(a cellphone charger i hear works?)

each fan has 3 wires and plan to wire all to one outlet cord. any help would be great thank you

yes you need the cell charger because it puts out 12 volts thats what the black box does on it, converts 120vac to 12vdc. the yellow wire is for 5 volts so you wont use that one the red wire is power for 12 volt and the black is ground.

You should use a 12 volt AC to DC transformer (aka cell charger) if you use one that is less than that the fan will run much slower and in turn be less efficient and move alot less air.

I have used pretty much all wall adapters for pc fan power supplies. Even if the volts are slightly under the fan will turn well enough with the proper amps.

most cell chargers are 5.5 volts get a 12 v charger or they like someone else said will turn slower

Anyone have a specific model of phone they know uses a 12v dc converter? Current so it's easy to find one. Thanks.

Yes. That is a 5.3 v charger. If you have a Fry's electronics in your town they sell a 12 volt 1.0 amp ac to dc converter for about $8. They sell them at radio shak too, but they are like $25.

how many fans are you trying to run? you can run more than one off the same charger.

You can look at your fans, or the box they came in and it will say how much power they use, usually written in milliamps (mA). Your charger puts out 200 mA, so You can use however many fans it takes to reach that number without affecting their power.
