And for me, I usually have 4 machines set up at a time ( big liner, small liner, Etc.....). So that cord gets used. And my power supply is the new eikon es400. It's perfect. The soldering lugs on the micro jack are so damn small and can't handle the daily use of tattooing from set up, use, cleaning and so forth. I started making my own and they have lasted a little longer but still Takes a shit on you in no time..
