Welcome to ECF Shayker...
There's really only one RTA that has the air flow of a genny or RDA. No, not the Flash E-Vapor, not the Fogger V4... and certainly not the Taifun, Kayfun, Aqua or sQuape.
The
GUS Estia is, for now, about as close as you'll get. They are run with 3 coils - designed for 3 coils and deep sub-ohm resistance - and capable of, more than adequately, supplying juice to all three coils.
Read a well photographed, and although a bit "gushy" and subjective, well written
review of the Estia by 'Qorax', here.
I can forgive his gushyness... they are a brilliant atty, and IMO, no conventional tank atty, to date, comes close.
If you're not a dedicated and fairly advanced builder, with pockets deep enough to drop $160 (at least until the Chinese clone them)... the Estia isn't the atty for you.
Although they don't have the air flow of a good genny or RDA (or Estia)... the Flash E-Vapor, and Fogger V4 perform (modestly) better than the Taifun, Kayfun or sQuape.
Note... SvoeMesto is working on an entirely new design.
