For the four-wire fan, all you need is the Black wire and the Red Wire. The other two are probably just for sensing and speed control.

• Connect the Red wire to the positive terminal of the cell charger
• Connect the Black wire to the negative terminal of the cell charger

On the unlabeled three-wire fan, i would look closely to see if there are any identifying marks that you didn't see. Once again, you only need two wires.

When I hooked my LED fan up with reverse polarity (on accident), my LED would give a flash of light but not stay on. When I reversed the leads, the light stayed on and the fan began to spin.

I am twisting the wires together and getting nothing is that enough or does it need to be soldered ? And on the 3 wire like I said light comes on but won't turn

I have no clue, but does the charger allow enough amps to start the fan? If you have a spare wall adapter (9 or 12 volt), cut that and use it to see if it powers your fans. One wire from the wall adapter will have white dashes or lines, this one is the positive lead. Attach that one to the red wire and the other to the black.

Could you post a picture - how exactly you did it?

Maybe troubleshoot your fans with a fresh 9V battery.
