I found I don't get the same vapor with the 4-hole as with my original 2-hole (all generic pen style atomizers). I haven't noticed a battery difference, BUT, I been wondering if the extra airflow over the atomizer might be cooling it too much and thus producing less vapor. In a sense, that could look like the battery is not providing the same power. Maybe if I draw slower...???
Just an observation, no data to back it up.
