I am a chain vapor i like to have 5-10 min sometimes upwards of 30mins sessions maybe twice a day will i be able to do that with a rba ?
You can chain vape anything that will wick fast enough to keep up and not get too hot. IMO any rebuildable can be made to wick fast enough, so that leaves heat.
I use a Kayfun at around 0.9 ohms, a AGA-T at 0.7, a Aqua dual coil Kayfun at 0.5, a Reo RM2 and Chalice bottom fed attys at around 0.5 ohms and a Trident dual coil dripper at around 0.5 ohms. None of these can be chain vaped for 20 minutes without me having to stop to let them cool down.
As you can see I'm vaping between 20-25 watts. I think even if I cut that back a ways I couldn't make any of these attys last that long without getting too hot. Maybe 5 - 10 minutes, but that depends on how many drags you're taking per minute and the watts.
I suggest you get a couple or three setups and alternate between them in a vape session. IMO the bigger attys like the Trident rda with fairly big air holes for the power would do best for this application.
As a side note, I used to use carto tanks a lot for a while before I got into rebuildables. Not as good performance as rebuildables, but IMO the next best thing. They don't heat up as fast as rebuildables but I don't know if one of these would get you 30 minutes either.
