I'm sorry for giggling but I saw your questions..................once you have so many posts, not threads.....you can explore other parts of the forum.
For a specific e-hookah and not an e-cigarette, I am not sure if there is a specific forum for that. I did a quick search and didn't come up with anything specific. "Ask the Veterans" perhaps or "General E-Cigarette"
If it is just an electronic cigarette, an eGo battery starter kit, perhaps an EVOD kit is a good start
