Hello fellow vapers! I am a newb to vaping and I bought a volcano e-cig to give it a try. So far it is working ok, but I would like to get more vapor. I have done some research online and I have heard that batteries can have a huge impact on the amount of vapor an e-cig can produce. Does anyone know if there are other batteries that are compatible that I can use? Or if there is another way to produce more vapor out of this particular e-cig?
