The iPower 80W is a full sized mod, not a mini. If you want something small, this isn't it, although it's not huge, it is easily twice as big as the first two you named.
As for RBA or RTA (rebuildable tank atomizer), any of them with a 510 connection will work with all three mods you named above. An RDA stands for Rebuildable Dripping Atomizer -- these don't have tanks.
