Yes you are right about buying an expensive atty for it.
I was thinking about drippers but i will have to carry liquid always with myself, this is something which is kinda hard for me.
I will try for kayfun or taifun mini
Also for future perspective if i want to update my battery what you would suggest will work
Istick 20 or 30 or kbox or something else
I haven't understand about sub ohms and i don't think i will be vaping on sub ohm in near future also.
But yes i will be needing something to chain vape type thing, not just 3-4 drags and leave the batttery to cool down as i have to do sometimes for my ego
