RDA is a type of atomizer used in vaping devices letting the users build their coils and wicks. It stands for "Rebuildable Dripping Atomizer." Unlike tanks that store eLiquids, they require users to drip e-liquid directly onto the coil and wick manually. RDAs are popular among vapers who enjoy experimenting with different setups to achieve the desired vapor production and flavor.
So, such technology ensures more customization of the vaping experience. In particular, the users can adjust the amount of eLiquid, the type of coil, and the wick material to their liking. However, using it safely requires specific knowledge and skill. Improper building or use can result in overheating or short-circuiting. Enjoy your vape RDA knowledgeably.
