You can get those coils to work better. It seems that some of the BVC coils have an airflow issue. It is more prevalent on the 1.6 than the 1.8 because of the coil size. To fix them, you need only a partially unfolded paperclip. You should be able to stick the straightened paper clip straight through the middle of the BVC coil. If you start from the open end, you should see the tip of the paperclip down through that tiny side-ways hole on the base of the positive connector piece. -If your paperclip doesn't go all the way through, you have to clear a path so it will. You must be careful. You want to work the paperclip so it pushes the ceramic wick away from the areas that are blocking airflow. Just be gentle and it will work. -You can test the airflow of the coil even before you put it on the Nautilus. Just blow through it like you would a whistle. You will know if the coil needs to be fixed. The whole process only takes a few minutes. You can make almost every coil work well for you this way.
In my opinion, 60 watts is more than enough for most people, especially those who tank vape. I mean, I get that many people feel they need 150 or 200 watts, and I get it. I mean, for a few extra bucks, why the hell not? I don’t need much wattage over 50W and Joyetech is marketing to people who feel the same. I can’t wait to see how the eVic-VT does a few months down the road, especially against other big name and popular devices, though I am concerned that the 60W limit will hold this thing back.
So why not more than 60 watts? I think the answer is simple. Joyetch wanted to allow usb charging and to accomplish this the battery had to remain low amperage. If you want USB charging, well then you can forget about devices that are powerful enough to pull out 100w plus, these require a battery with more voltage than a usb charger can handle.
