RDA vs RBA - What Is The Difference?


"What's the difference between RDA and RBA? I'm still confused because in forums and other places, I see pictures of stuff people call RDA or RBA but they all look the same to me. Coils with wick or cotton or whatever it is in there."

You have probably came accross exactly the same question dozens of times when trying to find what the whole fuss about RDAs and RBAs is. We have already explained what a Rebuildable Dripping Atomizer (RDA) is in our previous blog post, but we will briefly cover the subject again to demonstrate the difference between Rebuildable Atomizer (RBA). 

RTA stands for rebuildable tank atomizer and both the RDA and RBA fall into this category.

RDA is a rebuildable dripping atomizer typically having a short 510 base with one or more coils with a small juice well to drip juice into. It allows for small amounts of juice to be consumed per application as the user simply saturates the wick and vapes the amount of liquid on the wick. It’s great for those wanting to carry and vape a lot of different flavours and gives great throat hit, flavour and clouds. You can replace wick or coil easily and tune ohm output. However, the wick or coil can not hold a lot of e liquid and you need to refill liquid frequently.

RBA is a rebuildable atomizer which comes in many forms and has a RBA deck with an RBA coil and is enclosed in a tank. It is used mainly by those who are not “vape fanatics” and has its pros and cons. One con is that one must use up all the juice in the tank before being able to change flavours. The big pro for the RBA is that you can just pick it up and head out without needing to constantly add more juice each time you use it. But it is not easier to change wick or coil as RDA. Most of the time, these tanks will be made out of some transparent material like plasic or glass although all-metal ones do exist. Some examples would be the RSST, Russian 91, Ithaca, Kayfun, etc.

Nowadays more and more e-cig users tend to choose RDA and RBA for higher vapour production and better taste. Some of e smokers may wonder a rebuildable dripping atomizer with no tank really works? Since you can drip e juice straightly on the wick, RDA is an easy electronic cigarette setup. With a tank to hold extra e juice, RBA allows you to vape in longer time before refill it.

Rebuildable atomizer safety
Although vaping experience can be customized by using rebuildable atomizer, you have to create coils and do an electronic circuit. Sometimes battery overload and e cigarette explosions will occur because of dealing with wattage, voltage and resistant improperly. So safety is the most important thing for all e-cig users and you should learn as much as you can before DIY.

The basic knowledge about rebuildable atomizer:

Generally the batteries to power RDA and RBA are 18XXX series of batteries. The number of 18 means battery width and the length is the second two numbers. It’s very important to know your battery’s capacity and whether the limits are huge.

The heating coil is made of Kanthal A-1 resistance wire, which allows electrical conductivity at hot temperature. Wire thickness determine its resistance, which means the larger gauge number of round wire, the wire is thinner and the more resistance, while the larger gauge number of flat wire, the wire is thicker and the less resistance.

Ohm reader:
Screw rebuildable atomizer onto a box with digital display known as ohm reader before do anything things to your wicks and coils. If nothing displays, you have to check the atomizer.
