The acronym "RBA" stands for "ReBuildable Atomizers", an important category of vaping atomizer systems.
RTA's and RDA's are both types of RBA. The RTA (Rebuildable Tank Atomizer) is a tank system and the RDA (Rebuildable Drip Atomizer) is a dripper system. With rebuildables, you "build" your own coil. In other words, you physically wrap a coil, attach it to the system and add a wick. There are many different builds, each one depending on the RBA type and the desired vape the user wishes to achieve.
