Hi I am new at this what is a cartomizer and how does it work.
Until you have to refill it with fluid. I just don't like the idea of modding to refill a cart.I would think that having the cart and atomizer all in one would be easier.
For what device?In the review you did which battery had good time before charging
I meant how was the battery life in the one I mentioned in comparison to other long life battery types the 7 volt ones
