price convenient top filling
been waiting for such a modification for a long time.

the length added to your subtank is actually not that much, here's some figures for you. subtank base with mod tank is 50.25mm, top to bottom excluding 510 and driptip. original subtank mini overall length is 48.50mm. only adds 1.75mm to your subtank, fantastic init??

if you are using the aerotank coils with this mod tank, guess what. you can fill up to 5.6ml of juice into the tank. 1.1ml more than conventional filling method.

chimney tube id is wide enough to take aerotank coils (SKU 2438803) without modification. you'll need to change the bottom o-ring of the coil to SKU 2156302 or SKU 2071201. positive pin of the coil head has to be pulled out by about an mm to make contact with subtank base's 510 pin.

NOTE: subtank nano's chimney tube has a much narrower id, aerotank coils will not work without modification to the stem.
