I have to admit that I'm a tad surprised you'd specifically address me, Michelle, with this question.
The three recent threads I most remember interacting with you in recently were:
Burning cartomizer battings, juice consumption, and pre-vaporization/incomplete vaporization ("rocks")
So now you want to take a cartomizer designed for ~3 watts and cram substantially in excess [fresh charge] of 8 watts through them? More power to you [pun intended] - but next thread, I get to point and laugh...
My advice: Pin the manufacturer of your device down on specifically what cartomizer at what resistance and with what "
vaping style" they're designed for. Then adhere solely to that. When experiencing problems, stick to their forum area and give them hell about
their device, leaving the cartomizer choice/vendor
entirely out of it.
[Note to the casual observer: don't ask for my opinion unless you want it...
