I have safecig batteries. I attempted to get an adapter so that I could use my 510 cartos with it, since I have now switched to 510 models (I have a high voltage kgo that I use low resistance cartos with, and a random 510 battery that I use 4.0 ohm cartos with). Be aware that this may not work. I tried to use my non-low resistance cartos with the adapter. When I puff on it, the tip lights up as normal, but no vapor comes through. Not sure if it's a faulty adapter or if the battery isn't strong enough to draw the vapor through.
