Compatibility Fan: 4Pin 12V Fan less than 8W (This is a 4-pin connector, but you can see only two wires are connected. The other two pins are empty because USB power only requires two lines). Easy to Use: Simply plug the USB into an adapter or computer, connect the 4-pin end to the fan, then turn on the switch and adjust the speed with the dial.
