The variable voltage ecig is a kind of advanced personal vaporizer which can adjust the output voltage on demand for those experienced vapers.
This “Safe Vaping Power Chart” below will give you a quick reference to choose the best voltage to work with the resistance of atomizers. Of course, alot depends on personal taste.
The resistances in this chart from “1.0ohm – 4.0ohm”, and the voltage from “3.0V – 6.0V”, this will meet most of the vaping devices in the market. The numbers in the color cells are “Powers (W)”
