Cheyenne Tattoo Hawk Adapter 3.5mm to RCA Plug.

This 3.5mm female audio jack (the same one used by Cheyenne machines and power supply) converts to RCA male which can be used to plug into power supply units that use RCA or for other RCA connection purposes.  NOTE that the 3.5mm female audio jack base is too wide for some cheyenne machines and so the way you would connect it would be via the end of the cable that plugs into the device you are plugging into.
