Q: Why use Joules ?

A: Because it is not enough for users to know the output Voltage or Wattage, at a set temperature, it's more important for users to know exactly how much smoke volum did I vape. It's more accurate than knowing how many puffs you vaped. Because someone 1 puff 1 second, somebody 1 puff 2 seconds and other one 1 puff 1.5 second etc.). Joule took time into account, very precise, clear and scientific.This is a innovation of YiHi, everything is from the user's point of view.
