RBAs are simply rebuildable atomizers. They may or may not have a tank or some other type of storage for liquid. The liquid is dripped onto the coils manually or held in a storage tank and vaped through the user-built coils.
RDAs are the easiest to use and also have the best airflow and vapor production of all types of rebuildable atomizers, making them the usual first choice when moving from a cig-alike. There are a few other choices with small but significant differences.
There is not usually an e-liquid storage. It takes only a few seconds in which the e-liquid bottle again to drop a few more drops on the rebuildable deck. If you want to get more information about RDA tanks, then you can pop over this website.
Some people prefer to use a Squonk atomizer with a special mod, usually called a squonk mod or squonk box. It is the same design as an RDA but there is a hollow pin in the center where the E-liquid is dispersed from a soft bottle below it to moisten the cotton.
RTAs are rebuildable tank atomizers. They have a tank to hold the e-liquid, but the user builds their coils. Vapers who just can’t stand the inconvenience of taking out their e-liquid bottle every four puffs love RTAs.
The build deck is most often smaller than an RDA, which is a major drawback for those who like to build. Airflow is inferior to RDAs as well because the coils are submerged in the tank.
RDTAs are Rebuildable dripping tank atomizers. Although it used for dripping as an RDA is, the rebuild deck is similar as is the performance.
