I have a eleaf istick 30w. It was working great but tank not getting connection. Where can I buy a tank top for this
Hi Danorb, welcome to VU.
It's possible that the center pin, where the tank connects to the iStick, has been pushed down a bit. They sometimes do get stuck, but you can gently lift that with a small flathead screwdriver, or even a small set of tweezers. It should make contact after that and, hopefully, you wouldn't have to replace your tank.
If this doesn't take care of it, you can use any tank that has a 510 connection, most do.
