I'm beginning to think that the NC2 really isn't the device for you, and I mean that in the nicest way possible.
I was going to post a description of how the regulated mode on the NC2 works but, I'm afraid I'll just confuse you further.
If I'm wrong let me know and I'll have another crack and at describing all three of the NC2 modes for you.
Mechs and VV devices are for vaping nerds and ludites who like a bit of recreational maths and making things awkward for themselves. If you just want to blow clouds and you find this stuff hard to understand, then a variable wattage device where you can just plug in a coil and dial in a power level is a better option for you. Again, I'm not trying to be condescending or patronising I'm just genuinely interested in you getting a good vape.
I think doing something for the first time is always quite confusing. Thats why I join here to learn and understand more about vaping and ohms law. I don't want to be that guy who vape but doesn't understand the law.
I'm offended from what you've said. I just want futher information to fully understand about vaping.
Thank you ☺
