I still say this multi voltage Tekkeon Mod is the one to get and sure you can run Cartomizers and any Atty off of it, the nice thing is also besides it feeding the juice you can adjust the voltage to wherever you want say from 3.7v-8v and dial in your cartomizer or Atty to its sweet spot everytime, and every vape will be the same and right on with no power loss, you can also vape it while its charging on a usb cord. It has more pluses than many things I have seen on the market today
