RTA stands for Rebuild-able Tank Atomizer, is also a popular type of tank. It’s a tank atomizer with clear tank (can be named as clearomizer or cartomizer) or metal tank (can be named as cartomizer). Deck, tank, and chimney are three common parts of an RTA. Some hot RTAs are Gemini RTA, IJOY EXO RTA, and Geekvape Zeus RTA.

RTA 101
What is an RTA?

The acronym RTA stands for rebuildable tank atomizer, which is a tank system with a rebuildable coil. Unlike an RDA where you have to add e-liquid continuously to keep the wicks from getting dry. RTAs bring a whole other level of convenience to vapers. When using an RTA, you only need to fill it up and vape until the e-juice is finished and then fill it up again. Typically, an RTA comes with a building deck, a chimney that connects the build deck to the top cap of the atomizer, a glass tank, and a drip tip.

How to use an RTA?
When it comes to using an RTA, it's quite simple. First of all, you need to build a coil and install the coil on the build deck. After that, the coil will have to be wicked with cotton. Then you need to put the tails of the cotton into the wicking holes, fill the tank with the e-juice you prefer and wait a few minutes to let the wicks get saturated. After all the above has been done, you can now enjoy vaping. When you're vaping, air will come in the RTA via the airflow holes under or over the tank section and is channeled into the inside of the build deck. Before the air reaches the drip tip, it will hit the coil on its way to the chimney.

Types of RTA
Bottom Airflow RTA vs. Top Airflow RTA 

Most of the RTAs you find on the market today adopt a bottom airflow system. However, the bottom airflow system is prone to having leaking problems, so some vape companies have also designed RTAs with a top-airflow system. While the design has the advantage of being leak-proof, it may end up sacrificing the flavor.

Mouth-to-lung RTA vs. Direct-to-lung RTA
Mouth-to-lung and direct-to-lung are terms used to describe your vaping style. Mouth-to-lung vaping means you draw vapor into your mouth slowly and then inhale it to your lungs. Direct-to-lung vaping means you inhale the vapor straight into your lungs. In most of cases, RTAs with a small number of narrow airflow holes are a mouth-to-lung RTAs, while RTAs with larger airflow slots or multiple holes are direct-to-lung RTAs.

Single-coil RTA vs. Dual-coil RTA
Based on the number of coils, RTAs can be divided into single-coil RTAs and dual-coil RTAs. Compared with dual-coil RTAs, single-coil RTAs tend to consume less battery power and e-juice and requires less expertise to rebuild, due to its simpler design. While dual-coil RTAs typically produce a higher amount of vapor production than single-coil RTAs. Most single-coil RTAs range from a mouth-to-lung to a restricted-direct-to-lung draw, while dual-coil RTAs allow for more airflow.

Advantages of RTAs
RTAs are still popular among vapers around the world as they have a large number of advantages compared to other vape devices.
Compared with sub-ohm tanks with replaceable coils, RTAs generally have a better performance if they are built right. Besides, RTAs offer a lot more options for customizing your vaping experience as you can build your own coils. On top of that, you can also save a lot of money on coil purchases.

Compared to RDAs, RTA users don't have to drip e-juice continuously because they have a tank with a large capacity which allows you to enjoy vaping all day long after being filled. The second advantage of RTAs over RDAs is that most RTAs do not leak if not kept upright.

Compared with RDTAs, RTAs are more compact in size and easy to wick.

Some Tips You Should Keep in Mind When Building on an RTA! 
1. Keep your cotton fluffy 
One important thing you should bear in mind is that compared with densely-packed cotton, the fluffy cotton wick can absorb e-juice more effectively.  
2. Think about the PG/VG ratio of your e-juice 
How much cotton for your wick depends on the PG/VG ratio of your e-juice. For higher-VG e-juice, less cotton would be better. If you have a higher-PG e-liquid, then you use a little bit more cotton.
3. Make sure the coils span across the air slots
Make sure that the coils span across the air slots, especially with a bottom airflow RTA. If the length of the coil is too short, it will allow the wicks to drip e-juice into the air holes, which can cause gurgling and even flooding.
4. Not to overfill your RTA
Leaving an air bubble allows e-liquid to adequately flow to the wicks and exchange air for vaporized liquid.
