I think my adaptor is adjustable.
At the moment I'm using a kr8 battery and a 4081 atomizer.
It seems like my adaptor is adjustable so that I can control the airflow:
a) If I screw on the atomizer on first and completely, then the battery, I don't get as much airflow into the atomizer (
little or no airflow), and the battery side looks like it's not fully screwed on (but it really is electrically, it's only the external appearance that looks like it's not).
b) Otherwise, If I screw on the battery first and completely, then the atomizer, the atomizer will not completely screw on to the adaptor, and this allows
maximum airflow (too much air).
Basically the adaptor seems to be adjustable. The centerpost appears to be able to adapt as the user desires, and this means that
the airflow is adjustable when you buy an adaptor.
Now all I think is needed is for
an instruction sheet in a bag which the adaptor is shipped in. I would like to see suppliers include this important info. with the adaptor. I'm glad I found out, but if I hadn't, I would have thought something was wrong with my battery or atomizer, or something.
