My girlfriend has just got one of these that came with the isub g tank, and this is her first sub ohm mod. She's currently using it in variable wattage mode, but the mod also has a variable voltage mode. So my question is, what is the difference between the two, in terms of usage? I did a quick search online and found something that said they recommend keeping it in wattage mode for that particular tank, but it didnt really say why. I dont really know myself because my mod is just vt and vw.
Thanks!
Thanks!
