I've fiddled with my DNAs a bunch and one of the major perks of the new one is the 20w output. Not because I want to vape at 20w but because it also comes with better amp tolerance which means more coil options at different wattage levels without restricting the board. It also looks like it's going to run cooler (not that the original ran "hot") but lower temp means more mAh going into my face instead of the environment
