it's clear in his videos with detailed recording charge of the mod's output. You are a bit of an arrogant know it all, where I was just trying to be helpful (with whatever little knowledge I have), to the OP. I am not going to go get youtube links for you. ANY mod he has ever reviewed shows all the limitations of mods not being able to fire at certain wattages purely due to a voltage spec limitation at a certain atomiser resistance. His username is pbusardo. You can find the videos yourself. No one does more thorough technical reviews on youtube. See ya.
