I don't think it's the nic, but more to do with wire gauge and airflow. I started vaping 24mg and 6 years later I still vape 24mg... when increasing power, you need a tank that can handle that power and a coil . Both need to be dialed in to use that power correctly. I vape 24mg at an average of 25 watts in rebuildable single coil rta's like the gem, erlkonigin, aqua and kayfun mini 3 and they all do a great job. I really don't vape pre made coils , (although i have tried them) . Now my wife vapes a nautilus mini which uses a pre made coil and with that, upping the power would definitely make it taste bad or burnt because those coils and the devices airflow just cannot handle it. Rebuildables are another thing all together, they just perform on another level imo compared to pre mades and you can just dial everything in. I think the main thing with trying to reduce nic is keeping that throat hit, if your able to retain that TH while reducing nic, it's alot easier. Rebuildables like the km3, have great warmth to them and along with you being able to build yourself, you can dial things in better. Also increasing pg will help with Th
