My 30w Infinite zero clone isn't hitting as hard as it used to. I'd say it's performance was cut in half. Using the same build as I was, 28g 2.0 coil, 9 wraps. It blew clouds like an old coal train, now it's weak. I've tried rebuilding, different batteries, nothing works. I put my atomizer on someone else's mod at the same watts and it performed well like it used to. Not sure what's wrong!
