Would there be a big difference dropping down to 15mg on a nautilus mini with 50/50 juice compared to 18mg on an evod tank/kanger mow tank with 50/50 juice?
Tried 12mg on the evod/kanger mow and it wasn't strong enough.
I wouldn't recommend it if you a a new vaper. I started out with 12 mg. nicotine and I was constantly, almost desperately puffing, and I still smoked a few analogs each day. That was on a couple of starter e cigs I had. The owner of the vape shop I frequented, told me I wasn't getting enough nicotine, that's why I was constantly puffing and not feeling satisfied. I went up to 16 mg. and that helped a lot, but it wasn't quite enough, so I went up to 18 mg. and I haven't smoked an analog since. My nic craving is satisfied without constantly puffing. I still use one of my starter kits some, but I bought a 20 wat and two 30 wat mods that are all topped with Nautilus Minis. I don't notice feel like I need a different nicotine level in either my starter kit e cig or my other ones. Everyone is different, but I can't imagine you'd need a different nic level unless you are blowing big clouds or sub ohming or something else I have no understanding of.
Adding on to say I have always stuck to juices that are pretty close to 50/50 pg/vg, so I can't answer you about what a difference that might make to you.
Good luck with your vape and enjoy!
