What do the abbreviations RDA, RBA, RDTA and RTA mean?

What do the abbreviations RTA, RBA, RDA and RTA stand for? These are shortcuts from the vaping scene, from the world of e-cigarettes. Let me tell you what these abbreviations mean if you don't already know.


Sub Ohm Tanks

RTA = Rebuildable Tank Atomizer.

Great, how does it look in practice? The RTA is a tank whose coil head you can wind up yourself.
Reservoir means that the reservoir has a fluid reservoir. It's not necessarily given.
An RTA is a perfectly normal atomizer, whether it's sub-ohm, high-ohm, or any other ohm that doesn't have pre-made heads. The technical feature of this vaporizer is a closed system that works with small negative pressures that are created during vaporization (Kayfun principle).

Another technical principle is pressureless and based on capillary action (Typhoon clearomizer, stainless steel screen clearomizer). The capillary action is also part of the RDTA vaporizer.

Beware of incorrect information in the Vape Shop: Sometimes vaporizers that only come with ready-made heads are incorrectly referred to as RTAs.

A dripper is a dripper, a slightly more detailed drip clearomizer. Unlike the tank clearomizer, the drip atomizer does not have a tank.

Unlike a tank clearomizer, a dripper is an open system. Liquid is dripped through the DripTip onto the cotton wool every few puffs. Some drip vaporizers have a small liquid tray. Thus, 2ml to 3ml can be placed in a drip tank with cotton as a buffer.

RDA = Rebuildable Dripping Atomizer

But we can now also form RDTA. That would mean according to the previous explanations

  • Rebuildable
  • Dripping
  • tank
  • Atomizer

So what is that?

Didn't we learn that dripping and tank are two different systems? One is an open system, the other has a closed tank? Indeed, RDTA tanks combine both, at least from a marketing perspective.

An RDTA tank usually has a winding on top that draws the liquid from the tank below by capillary action. Basically this is an RTA with a special design. But the D is currently selling very well. RDTA is more of a confusing term, especially for the beginner

The market for RDA tanks is huge. The most commonly used winding deck is the Velocity deck, which is generously built and easy to wind. RDA vaporizers are made to produce huge amounts of vapor. Vaping takes place on the lungs (DTL - direkt to lung).

Currently very popular representatives of RTDA vaporizers are vaporizers from iJoy

This is not a tank type, but rather a component to turn a ready-made coil evaporator into an RTA (Rebuildable Tank Atomizer). This component is screwed in instead of the finished coils. The RBA is a self-developing unit.

The best example is the Subtank Mini *, more suitable for back steamer, which I myself only use with the RBA.

Or the popular TFV8, the steam beast that is more for lung steamers.

The shop then says something like: Tanks with RBA as accessories, the possibility to wrap yourself and the same.

These tanks with RBA unit are ideal for beginners who might like to try winding themselves, are not sure and can simply screw in ready-made heads in case of doubt.


Whenever you come across a name that starts with R and ends with A, it is a self-winding atomizer or accessory. The letters in between tell what exactly it is about.

RTA - Rebuildable Tank Atomizer / Self-winding atomizer

RDA - Rebuildable Dripping Atomizer / Tröpfelevaporfer to wrap yourself

RDTA - Rebuildable Dripping Tank Atomizer / Tank drip vaporizer to wrap yourself

RBA - Rebuildable Base (for) Atomizer / component, accessories for pre-fab atomizer
