Hey ECF! I recently purchased a Kanger Subbox Mini starter kit that came with a TopTank. I absolutely LOVE this thing. It came with a coil already inside the tank that says is .15 ohms but reads 0.29 on the display. I don't know much about how any of that works but I do know I'm vaping at around 30.5 watts and it's the perfect spot for me. What is different about the other coils? What does a higher ohm mean? There seems to be a few different styles of coil. Which of them would be good for vaping at 35 watts and under like I am now?
