Justdaveman....How did you get the Greencig or KR808d1 cartomizers to work with the Adaptever?.....please give details.

I am assuming that you have also used the adaptever at six volts. How do the cartomizers perform at 6volts...is the taste still good? How long do they last at six volts.....longer or shorter than when using them at 3.7v?
