Google Voopoo Drag X RTA.
The 510 connector on the bottom of this unit is magnetic and the top part will pull right off and fit onto your Drag Max. Then you can take the tank part off your Drag Max, put it on the 510 base, and use it on another device that will take a 510.
I eventually will stop using the factory coils, but I like them enough that I did buy 3 boxes.
Yes, I can see this will be hours of researching and eventually experimenting. There should be an RBA Tank to build and just pop on~!
