Dripping is a term used for a way vape without using chambers but rather placing drops of e-liquid right on the coils often atomizer. It's popular because of the fact that it gives off a bolder and richer flavor than traditional methods and because it's easier to switch from one flavor of e-juice to another this way. In order to do this properly, bridgeless atomizers are needed. Though e-liquid can be dropped directly onto the bridge, the hit is better when the liquid goes directly onto the coils. And thus, the different methods for getting the bridge out of the way are where RDAs come in to play.
RDAs stands for rebuildable dripping atomizers which are a DIY alternative to buying atomizers that come prefixed and ready to drip. Traditionally, in order to get the effect of dripping, vapers would have to take apart their atomizers and remove the bridge piece in order to expose the coils so e-liquid could be placed directly onto them. When the popularity of dripping rose, atomizers without bridges became available and so did RDAs. RDAs are a popular choice that gives vapers the option to create their own bridgeless atomizers at a lower cost than those that come pre-made that way. RDAs allow users to replace wicks and coils themselves.
Now, there's an art to dripping that involves using the correct amount of e-liquid to achieve maximum drags without losing flavor or having the liquid come dripping out of the atomizer. It's important to consider that when buying a RDA, care needs to be taken to build the coils and wicks correctly or the e-juice could lose flavor. It's important to do research and choose the right rebuildable atomizer or risk wasting e-liquid and money on an apparatus that isn't effective.
When looking for which RDA to buy, it's important to consider several key factors such as the number of posts. The more posts in the RDA, the more coil setups which means more vapor. Next is airflow control. The amount of controlled airflow in the device is directly related to vapor and flavor; more airflow means more vapor, less airflow means better flavor. The decks on RDAs are important factors as well because they determine how much of a wick and how much liquid the device can hold.
