What is an RDA, RTA, RBA?

In this post, we will talk about the different types of “clearomizers“. They are generally referred to as “repairable” but practically it has got to do more with the user and the user induced resistance also known as Atomizer. Entering the subject of the terms we are learning, I will comment on them below.


” Rebuildable Dripping Atomizer” in Spanish drip repairable atomizer or dry vaping atomizer. This type of atomizer does not have a tank; simply the liquid is placed with the dripper and when it dries we re-impregnate it. It is noteworthy that this type of atomizer is used to taste liquids and obviously for what they call “Cloud chasing” or “vaporadas” in Spanish. 


” Rebuildable Tank Atomizer” This repairable atomizer, unlike the RDA has a tank containing the liquid that we vape and its capacity varies according to the manufacturer. Normally the capacity ranges from 3 ml or less to 7 ml. 


” R e buildable Atomizer”. These atomizers are basically the same as an RTA but unlike them, they have the capacity to use both repairable resistors and commercial resistors. 

Resistance “Coil”: In the case of atomizers that use commercial resistances nowadays, the differences are in the way in which these are elaborated. These resistances are manufactured with a resistive thread that can be of different material; one very common is the Kanthal thread, then we have nickel thread, titanium, and stainless steel. These threads are in different thicknesses which, when we elaborate the resistance gives a measurement that is expressed in ominous “ohm”.

As we see in the image, it is an RDA with a resistance meter and the wire we see or thread is in the form of turns in the silica braid, the most common is the use of Japanese Cotton

The development of the resistances is relatively simple, in the market we found several articles to elaborate them called Coil jig which has a drill bit or several of different measures, although some more experienced vapeadores use a screwdriver of approximately 2 to 3 mm. 

Depending on the type of resistance that we want to elaborate, the number of turns and the thickness of thread is decided but normally 6 to 8 turns depending on the thread are employed. There are many new styles of coiling that have been introduced in the market such as the “parallel coil”  or the more popular “Clapton Coil”. 

It should be noted that we will also find the term “sub-ohm” many times, that is to say, that its values ​​in resistances are below 1 ohm. 

The resistance once made is placed on the “wick” which again is made out of different materials- the most common being organic cotton or Japanese cotton. Silica and stainless steel mesh are also used, the latter being used by some atos not everyone.
