Okay, so I just inherited an eGo C Twist and I'm really liking it. I remembered seeing a voltage chart so I decided to pull it up and noticed that I have the voltage pretty high compared to what the chart says (I have it at 4.2-4.4), but I'm liking the results; no burnt taste, the vapor is a little warm but I kinda like that. My question is, I have a bunch of dual coil iClear 16's which I think are 1.8ohms. My question is, is that per coil or for the tank in general? I say I think it's 1.8 because my single coil one says it, but I don't see any reading on the dual coil ones. No multimeter handy so I can't actually check. Thanks for any input.
