RBA, RDA, RTA, RDA .. What does all this really mean?
RBA is short for for ReBuildable Atomizer, and is a generic name for RDTA, RDA and RTA. The RBA can in short be described as an atomizer where you do not use the pre made coils, your wrap them yourself. All RBA also use interchangeable drip tips. There are also sub-ohm clearomizers that can use a separate RBA deck (sometimes included, sometimes bought seperately) so it can use both pre made coils and coils you wrap yourself.
RDA, Rebuildable Dripping Atomizer:
When using an RDA you need to build the coil yourself, it has no tank so e-juice is dripped directly onto the wick / coil. You take a few puffs, when the cotton is dry you drip a few drops of e-juice. An RDA is used most for people who love them big cloudz since they often have a huge build deck to accommodate big coil builds, the airflow is often also huge. Is called a dripper.

RTA, Rebuildable Tank Atomizer:
An RTA is called by many an RBA, which is incorrect since RTA is a kind of RBA. However, an RTA has a tank like a clearomizer but the coil is built. The RTA has a smaller build deck than the RDA, less air flow and is used by those who want to focus on the flavors. In the recent future we’ve seen lots of RTA coming out with bigger build decks though.
RDTA, Rebuildable Dripping Tank Atomizer
Despite its name, this is no dripper (RDA), its more of an RTA with a bigger bild deck. That means you get the best of both worlds: You can build awesome advanced coils, while you still get a tank to hold the e-juice.
