i use my passthrough with a single ohm 3.0 cart. it consistently stutters, ill start to inhale, works for a second, stops for 2, works for 1, stops for 5, works for 2, you get the point. is this normal? i am using the adapter from vapor4life. not sure if my car puts out enough power through outlet for this but i have a 2011 sonata so i would think it should. i tried exchanging the adapter but that didnt help. any ideas?
