hey all, pretty new to all of this, a friend of mine gave me two of his vape, a tesla stealth 40 and a phantus mini. I also received a tank a baby smok x. Can anyone point me to resources to better understand how to use a mechanical mod like the phantus? It didn't come with a tank as he never ended up using as he said it's complicated. I like to form factor tho so I kind of want to make it work. I have been reading on basics about ohms law but it still very complicated. The tesla is fun tho and easy to use!
