Hello everyone. I have a question that may sound silly. But here goes. What determines the intensity of the throat hits, vapors and the flavor? From reading around the forums, all of the power seems to center around the battery. I got some new carts today for my RN4081 and there seems to be a noticeable, yet satisfying difference in the new carts' intensity. Seems that the carts and the e-liquid caused the difference. I am wondering if this is just my imagination or if this is really true. I am still very new to vaping, so I hope I was able to explain properly. Knowing this, would help me make my next decision regarding an e-cig upgrade.
