The acronym "RBA" stands for "ReBuildable Atomizers". It is an essential category of vaping atomizer systems. The RTA vape (Rebuildable Tank Atomizer) is a tank system and the RDA (Rebuildable Drip Atomizer) or RDTA (Rebuildable Dripping Tank Atomizer) is a dripper system. If you have rebuildables, then you easily "build" your coil.
