Best RTAs Introduction
RTA’s or rebuildable tank atomizers are like ‘sub-ohm’ tanks but without the pre-built coils. Instead, they come with an RBA deck so you can fine-tune your vaping experience and build the coils to your preference. There are countless options in build-deck styles, coil configurations, and e-liquid capacities – which means the best RTA for your needs is out there somewhere.
Rebuildable tank atomizers are now delivering comparable performances to RDAs, with just as many options in build decks and setups. Whether you are looking for a single coil RTA, dual coil RTA or even a mesh coil RTA, we’ve got you covered.
Our Best RTA vapes list will help vapers looking to start with their first RTA and those already looking for their next one.

Introduction to RTAs
There are three main styles of rebuildable atomizers: RTAs (Rebuildable Tank Atomizers), RDAs (Rebuildable Dripping Atomizers), and RDTAs (Rebuildable Dripping Tank Atomizers). All three types require the use of a coil or coils, which are made by the user. A small rod has the wire wrapped around it, usually 24 mm in diameter. The user must then create a wick to help transport the e-liquid to the coil(s).
You can use a variety of wire types. The most common is Kanthal A1, which should only be for variable wattage (VW) mode. It has a very stable resistance when heated. Other types of wire include Titanium and ni200, which can be in temperature control (TC) mode due to their varying resistance when heated. Stainless steel has become very popular as it can be used in both VW and TC modes, as it has a slight variation in resistance when heated.
Many different types of wicking materials can be used for vaping in rebuildable atomizers. Cotton or rayon is the most common.
What is an RTA?
Why is an RTA different from other types of an atomizer? RTAs have a building deck where the coils are placed at the bottom, while the tank for e-liquid will sit above the deck. RTA’s do vary in size but can hold anything from 2ml to 10ml of e-liquid.
They then have a chimney section surrounding the deck, which allows air to flow up from beneath the deck, hit the coils, and flow up the chimney to the mouthpiece or drip tip. Some newer RTAs also have top airflow, which can come down the outside of the chimney stem to hit the coils and then back up inside the chimney to the drip tip. RTAs will contain slots or holes in the deck to allow e-liquid to feed on from the tank through to the coils’ cotton wicks.
An RDA will have significantly less liquid capacity than an RTA, as it doesn’t have a tank to hold the e-liquid. It only has a small well in the bottom.
The atomizer has the coils at the bottom, and the wick will dip into the well of liquid to feed the coils. Since the juice is below the coils’ level, they do not require a chimney section, which also means the coils. Therefore vapor is closer to the user’s mouth, generally providing better flavor and more vapor production.
They also have a top cap that sits on top of the building deck. Air will enter from the top, bottom, or sides and then rises from the top cap to the drip tip.
RDTAs are like a combination of both an RDA and an RTA. Like an RTA, it features a tank, but it sits beneath the atomizer and the build deck like an RDA. Making it is similar to having a very big RDA well. RDTAs like RDAs also have a top cap, so the air flows from that directly up to the drip tip.
Different Types of RTA Vapes:
RTA is a broad term that refers to any type of rebuildable tank atomizer (RBA). There are several types of RTA, although they all fulfill the basic definition given above.
- Standard RTA: Most RTAs are similar to sub-ohm tanks, but they have a deck at the bottom of the tank that contains two or more posts for connecting your own coils and wicking channels to absorb liquid from the surrounding tank.
- Genesis-Style RTA: These RTAs are very similar to standard RTAs. The only difference is that the deck is in the middle or above the tank sections with the wicks hanging down through the bottom and into the tank.
- RDTA: Rebuildable dripping tank atomizers are very similar genesis-style RTAs with the deck above the tank section. The deck acts just like an RDA, but the wicks will cover holes sitting above the tank and will saturate when the tank is tilted. You can also fill the tank up separately.
- Sub Ohm Tanks with RBA Heads: These are pretty much as described. There are several Sub Ohm tanks on the market that also feature an RBA coil head (rebuildable atomizer), which enables you to turn your favorite sub ohm tank into an RTA.
Rebuildable Atomizers for Beginners: What are the Best RTAs for New Vapers?
If you’re a beginner, the world of rebuildable tank atomizers may seem intimidating. It means changing from an easy push-in/pull-out pre-built coil head to a more technical process of wrapping your own coils and understanding resistances.
For this reason, rebuildable tank atomizers are more complicated than standard vape tanks and are generally only recommended for more experienced vapers.
However, there are some key factors to help find the best rebuildable atomizers for beginners.
- How many posts? The majority of rebuildable tank atomizers today use a two-post design. This is the approach that most tanks in our best RTA list above use. However, it’s also becoming common to see postless decks. You may find some older RTAs have screws to trap your wire under, but newer RTAs will have open holes in the posts where you screw down to capture the coil legs. If you are new to RTAs we’d recommend going with an RTA tank with a two-post or postless deck.
- How much space does the deck have? The amount of space you have in the deck to place your build (coils) in is also an important factor. Larger decks are easier to build on, so the best RTAs for beginners will tend to be those with larger build decks.
- How do you wick it? Wicking an RTA can be one of the most challenging aspects. It may be easy to over wick (causing dry hits) or under wick (causing flooding or leaking). Therefore go with an RTA that is known for being forgiving with its wicking. Generally, the best RTAs for wicking are those with larger wicking channels.
In our list of Best RTAs above, we have indicated what we feel is currently the best RTA for beginners. However, if you want more options check through our detailed reviews here.
Advantages of RTAs over other atomizers
Ok, so what are the benefits or advantages of having an RTA over a Sub-ohm tank?
The primary advantage over Sub-ohm tanks is the freedom of not having to buy factory coil heads. Because you are wrapping your coils, there are considerable savings to be made. Regardless of the material type, an entire roll of wire is approximately the cost of two factory coil heads. A roll of wire can also make several coils and potentially last you months or even years. Likewise, a pack of organic cotton or rayon for wicking is also very cheap and could last months and years
Users also can keep the coil in place and replace the wick, given that the built coils have a longer lifespan. Furthermore, users of sub-ohm tanks have to rely on manufacturers to provide the bespoke coil heads for their tank, which can sometimes make them tricky to find with new advances in coils.
What are the advantages of an RTA over an RDA?
The first advantage is the e-liquid capacity. If you are using an RDA, you have to drip more e-liquid onto the atomizer to keep vaping continually.
Therefore vapers of RDAs have to carry a bottle of e-liquid with them. In contrast, an RTA (especially one with a large capacity) may provide vaping enjoyment all day before refilling is required.
The second benefit of an RTA over an RDA is that most tanks do not leak e-liquid when they are tilted sideways or inverted. However, due to the nature of the design of RDAs, as they don’t use a chimney section, they can leak if placed sideways or inverted.
Tips & tricks for the best RTA experience
Here are a few helpful tips if you are using an RTA. The first piece of advice is to ensure the coils span to cover the air slots, especially on bottom airflow atomizers. If the coil length is too short, it may allow e-liquid into the air holes, leading to flooding and gurgling. Another tip to prevent flooding is to make sure the wicks do not allow e-liquid to flow past them and onto the deck. The tails of the wick must adequately block the juice feeding holes and slots.
However, if an RTA begins to give you dry hits, then it might be that you have used too much wick, which is then blocking or hindering the flow of e-liquid. At first, it can be tricky finding the right balance, but it is key to having a top-performing RTA, and practice makes perfect. Some RTAs, especially new ones, are more forgiving and easier to build on, and you will also find most allow you to access the build deck even when the tank is full.
This access means you can re-wick it at any point if you have problems, and these types of RTAs are definitely a better choice for beginners. Finally, be careful when filling your RTA vape tank. Make sure you don’t overfill it. Leaving an air bubble allows the e-liquid to flow better to the wicks.
