That wouldn't work too well with the ProVari.....(being that it has the 510 connection only). I don't really like using the adapters on it. Good thing that your iStick kits are coming with the adapters with them. I got an iStick for a buddy of mine @ work (w/o the adapter and charging cable), and had to give him a couple of adapters. He was using those old style Aspire Ego ETS tanks on it. He had nothing but problems with it working, and now I have to send his iStick back. I can only hope that the new one works as well as the other (4) that I have purchased for myself, and others.
