RBA is an acronym for Re-Build-able Atomizer, most likely spelled out “R-B-A”.
An RBA might refer simply to a rebuildable section offered with an otherwise normal tank (normally requiring replaceable coils) as an option for users who might like to try rebuilding. Dedicated RBA types include:
- RDAs or Drippers
- RTAs or Rebuildable Tank Atomizers
- RDTAs or Rebuildable Dripping Tank Atomizers
- Kayfun styled tanks
- Genesis tanks
