From the looks and capacity of your Smok GBC clearomizer below, if you're using it on an eGo type pen set-up...it must be a good-sized battery that you're using...not a regular eGo type 14mm diameter one.
Smoktech GBC Clearomizer
If your battery(s) are still working for you and you can hold off on ordering a new tank or whole set-up for a little while...to try a tank that's a similar large capacity, takes easy to replace, readily available, and inexpensive coils...I'll send you 1 to try for free. It's a glass tank, so it's heavier than your GBC clearos are, but it provides really good vapor and flavor. Another ECF member sent some of them to me...to pass along to a member I was helping, who was in a similar situation as you are. However...she's elderly and has no longer been responding to emails. Not sure if she's still even "with us".
In any event, if you'll PM me your mailing info...I'll send you 1 of the tanks and several coils, to see if it will work for you. If it does, I'll then send at least another 1 or 2 to you.
