I am totally new to vaping. I just ordered my first setup last night which includes a Kanger Mini Protank and an EVOD EGo clearomizer, along with a Vision Spinner 1300 vv and an eGo C Twist VV 900. I was wondering what the ohms are on these items? I googled it even but did not seem to get much of answer. In a different forum topic I was told to get a "variety of different coils for your toppers." This may be a complete n00b question.....but the items do the items I ordered already have coils built into them? I imagine he was just referencing the fact that I can take about the topper and change the coils myself, but I want to make sure lol. I would hate for my setup to get here, only to find out I didn't order everything I need. I bought what I posted above, plus juices of course. I should be good to start?
