Rebuildable Atomizers IconRebuildable atomizers are also referred to as RBAs and they include the type of devices that work with user made coils. The term ‘rebuildable’ comes from the fact that once the resistance gets burnt or produces a nasty taste, the user can easily make a new one and replace it with the help of a screwdriver. These devices fall into two distinct categories – rebuildable tank atomizers or RTAs and rebuildable dripping atomizers or RDAs.
