Although almost all e-cig batteries are rated at 3.7 volts, you’ll find that your vaping experience changes when you use different e-liquids, atomizers, tanks and cartomizers.

Some combinations may produce rich flavour and full-bodied throat hit, while others may leave you wishing you could “crank it up a bit” either in the vapour production, taste or throat hit.

Variable-voltage electronic cigarettes allow you to do exactly that, making it possible to change the voltage of your device to achieve the vapour production, flavour and throat hit you want.
