So I've been looking through different posts and I'm still confused about the difference between watts and volts. I'm looking at buying a vv4 and I figured it would be a good idea to understand what exactly I'm buying before spending the money on it. While I was looking through the forums, I saw words like sub-ohms and ohms being thrown around so IF someone wants to explain that I would be eternally grateful otherwise that's the next lesson I'm planning to learn.
