I found a post that made sense when it comes to voltage and ohms. He, I don't remember his name nor could I reply in quotes due to being new, said that you can take the Ohm reading and just add two to the number. So, from what i gathered, I am vaping a 1.5 Ohm kanger protank 2 rebuilt head on my Itaste SVD with the volts at 3.5 and watts at 8.0 This sounds like a good rule of thumb to follow. Does anyone else have any other tips for a new guy to vaping?
