Nice to see you over here, Jeremy!
Yeah the guys above really nailed it. You'll find that when/if you start building your own coils, then you can experiment with higher wattages....the 'premade' coils in the clearomizers you mentioned are simply not designed for higher wattage power....
For instance, I just built a dual coil setup in one of my dripping atomizers, and the resistance came out to 0.5 Ohms. At, say, 4.0 volts in my mechanical mod, I am pushing 32 watts.....Larger diameter wire can handle more power (I used 26ga. Kanthal wire - the wire in your Nautilus is probably much smaller in gauge), hence the higher wattage....and when you combine that with more airflow, you can run setups with higher watts...
