A606 Variable volt personal vaporizer
This device uses Pulse Width Modulation which will adjust the voltage dependant to what the load of the cartomizer/atomizer is. It has great vapor production and works really well with our 510 cartomizers. This PV has a multifunction switch that has 5 click on/off feature, to change the voltage click the button 3 times and adjust voltage by turning the switch clockwise or counter clockwise, while in vape mode turn the switch counter clockwise to check current battery voltage and cartomizer/atomizer resistance, turn the switch clockwise to check the working amp level. It will also remember your settings when the battery is changed !
