RDA is short for Rebuildable Dripping Atomizer. These devices are used to burn vape juice into vapor. They play a key role in the vaping industry and are the most popular type of atomizer among vapers. RDAs are called dripping atomizers because e-liquid is dripped directly over the coils as opposed to other atomizers that have glass tanks as a reservoir. All rebuildable atomizers are manually set up with wire coils and are recommended for experienced users only. Because these devices require a manual set up, users have more flexibility when creating builds. Some vapers may prioritize high vapor production while others opt for more flavor.
