No, there is no potentiometer, these are boosted fixed voltage, so you choose the voltage somewhere between 4 and 4.5(maybe higher) and he will set it to what you choose and then it stays like that. It is not variable voltage it is just boosted to give you a specific higher voltage than 3.7. The button is a touch switch and I have not seen any other choices. The 75 dollar one is just a regular 18350 touch switch mod and the 100 dollar one is the boosted version. They are aluminum not stainless steel.Well sort of, lol. So is there a potentiometer on these or not? I guess I am still confused....
Also are they stainless steel? Do u have to request polish? Can u chose the button? And are they $75 or $100?
Sorry again for the questions, thanks!!![]()
