A few hours ago I switched the PtoTank I was using from my Vamo to one of my Vision Spinners (1300 mAh) and the Spinner was way better on taste, th and vapor production. The tank is 2.4 - 2.6 resistance. The Vamo is set for RMS and the watts are set at 6.0. The Spinner is set at 4.2 volts. The Vamo is not moving from 4.1v no matter what I set the watts to. Moving the watts to 7,8,9 etc just burns the juice. Why is the Spinner outperforming the Vamo? Thanks for any info.
