That would explain why I'm getting a burnt taste on my new clearomizers. What a disappointment. They were sold as compatible with my KR808d-1 battery, but they burn the crap out of my juice. I bought the lowest ohm clearomizers I could find, which was 2.6-2.8... and my battery is a 3.7/4.2 volt model. That puts my wattage at somewhere between 4.89w and 6.8w. it tastes awful, so I have to be on the high end of that scale... Thanks for the v^2/o forumla.
