About the Watts

The main advantage of variable-voltage / wattage electronic cigarettes is, that they produce more vapor than the small E-cigs most people buy when they first start vaping (E.G. the cigarette look a like).

To understand the difference, let us take a look at the specifications of a standard electronic cigarette;
most devices use 3.7 volt batteries and 2.4Ω atomisers / tanks, and so producing a little under 5.5 watts of power.
To get a little bit more out of their E-cig, some vapers (Electronic Cigarette users) buy larger batteries and combine them with low resistance atomizers / tanks.(1.8Ω)

When you use a 3.7 volt battery with for instance a 1.5 Ω clearomiser / tank, the vapour production of the E-cig increases to over 9 watts.

This still doesn’t equal the performance a variable voltage / wattage e-cig can achieve (up to 12 watts at 6 volts with a 3.0Ω clearomiser / tank).

How do these E-Cigs work?

Most variable-voltage / wattage E-cigs use 3.7 volt batteries, just like standard E-cigs.
The difference is that a variable voltage / wattage E-cig has a circuit that stores and regulates power from the battery, delivering it to the atomiser / tank at the voltage / wattage you choose.

Many variable voltage / wattage E-cigs also have micro processors for safety (of the battery) and control over vapor production.

These advanced internal electronics often make variable voltage / wattage E-cigs more expensive than standard E-cigs.
