So I have been vaping for 2 weeks now and Istarted off using a generic e cig set up branded Xhale. Not sure if I'm using the right names but it had an ego style battery and a clearomizer. I started off using 24mg nicotine and it was working great. I just got a vamo v3 with a protank and now the nicoti e is kicking my ....! I'm not sure on the voltage on the Xhale but I'm using the vamo at 7.5 watts with a 2.2 ohm head (reads 2.4 on the vamo). Anyone know why this is happening?
