Hey everyone! I recently bought an eleaf Ijust 21700. I did my research on it to see of it was up my alley before I did. I love it! I know it is a regulated device, and has a max of 80 watts. But I'm curious as to how it works. Specifically, how it reads coil resistances and adjusts the power output accodingly. If anyone can enlighten me on this particular query I would greatly appreciate it. Thank you!
