Best RTA’s 2021: Top Rebuildable Tank Atomizers for Flavor & Clouds

RTA’S (Rebuildable Tank Atomizers) have become very popular in the last few years, and we all know why they have become popular, though.

RTA’s bring together the flavor and customizability of an RDA with its convenient and straightforward usage of the refillable tank. However, like many other traditionalist sub-ohm tanks, it’s harder to shop for pre-built and ready-to-use coils.

Instead, you have to build your coils yourself, wick, and mount them on the deck of the RTA.

But it can be not very easy for you if you are a complete beginner.

Therefore, we have listed out the five best dual coil RTA’s of 2021 due to their easy usage, build quality, flavor, and cloud.

1. Dovpo Blotto Mini

Dovpo Blotto Mini

The Blotto Mini is a dual coil RTA produced by Dovpo and designed by the famous vape YouTuber Vaping Bogan. This tank has a 4ml capacity, 23mm base diameter and large fill ports, which can fit any ejuice bottle.

It can also be used for single or dual coil builds.

The exceptional feature of the Blotto Mini is its wall that enhances and clasps your coils, and it forces the air to hit your locks from 242 degrees to deliver your absolute giant flavor and clouds with the help of the build deck on the sides of the Blotto Mini.

In addition, its build deck is passed by its two exceptionally more comprehensive slots that are placed at the base of the tank, and each space is made of 26 holes in the honeycomb pattern.

Since its airflow is entirely open, you can access the restricted direct lung draw that is smooth and off the record.


  • Good design
  • No leakage
  • 242 airflows with the smooth functioning
  • Small size


  • Not ideal for sizeable dual coil builds
  • Similar to the Blotto RTA

2. Wotofo Profile Unity RTA

Wotofo Profile Unity RTA

The Profile Unity RTA collaborates with Mr just right 1 (The maker of the Profile 1.5 RDA), and TVC (in charge of Drop RDA) has accompanied Wotofo to make one of the best RTA’s in the current times.

There is a 25mm diameter that holds on to the similarly convenient build deck since its RDA counterpart: a dual clamp and a mesh coil compatible deck, with a roller-bearing central support podium.

The podium puts pressure on your cotton to keep it connected with your mesh for effective flavor and performance.

The body of the Profile Unity has two notches that line up with the base of the tank for settling the top cap and ensuring that the airflow is always directed to your coil.

Additionally, there is a 3.5ml capacity of the Profile Unity that can be speeded up to 5ml with the existing glass tank.

Threading the Profile Unity can be a little more challenging in the initial days; however, once you are used to it, you will not invest in any other RTA.


  • Amazing flavor
  • Simple design
  • Significantly restricted lung hits
  • Top – Bottom wicking


  • Uses a lot of e-juice

3. Dead Rabbit V2 RTA

Dead Rabbit V2 RTA

After the success of the Dead Rabbit Series, the Dead Rabbit V2 RTA put forward the convenience of the tank with the same build deck with its four posts being shaped like rabbit ears to permit you to drop over in your coil and to after that trim your leads. Therefore, which means that for pre-measuring your tips.

Moreover, it has two wide airflow slots at the top of the device that tubes downward of the tank, indicating that the Dead Rabbit V2 RTA is leakproof, whilst many RTA’s don’t have this feature.

The Dead Rabbit V2 RTA tank can hold up to 4.5ml of e-juice with the bubble glass without amplifying the vaping and having to refill it.

You can quickly fill up the tank without any difficulty as the top of the Dead Rabbit V2 RTA is push-to-fill style and purely pushes back to reveal a single large fill port.


  • Amazing flavor
  • No leakage
  • Easy to develop on
  • Smooth airflow


  • Wicking can be difficult
  • Loud airflow

4. Wotofo Troll X RTA

Wotofo Troll X RTA

It is a remake of the classic Troll RTA of 2017; just like the original, the Troll X has a 24mm diameter and is specifically designed to produce excellent flavor.

Similarly, to other best RTA’s, the Troll X comes with two airflow slots that you can swap onto the build deck. They are:

  1. Honeycomb slot
  2. Another one with two wide slots

These two slots permit you to promote or stop the airflow from matching with your preferred coil setup.

The best part of these slots is that you can easily swap them without uninstalling your coils.

Also, the Troll X has a bottom airflow control ring with three sets of five horizontal slots that you can adjust as per your preference, and since they are paired with the side airflow, you can get rich, flavorful, and concentrated vapor.

Stuffing the Troll X is easy and can be done by sliding the open-top cap.


  • Outstanding flavor
  • Good airflow slots
  • Nice aesthetics
  • 4ml capacity
  • Solid build quality


  • Stern wicking
  • Difficult to fill with large bottles

5. Vaperz Cloud Trilogy

Vaperz Cloud Trilogy

The Vaperz Cloud Trilogy is a great RTA because its 30mm base diameter and its build deck is similar to the most popular Asgard RDA but in an RTA format. Its build deck is a single large intake shaft that passes the air straight from the 44 airflow holes under and through your coils.

This airflow design has a smooth draw and big clouds from a dual coil without the leakage problem.

In addition, the build deck is straightforward and clean; thus, it’s easy to use. Drop a pair of coils in the post less build deck and protect the leads with the flathead screws on its side.

Although some RTA’s can be difficult to wick, Vaperz Cloud Trilogy isn’t: it wicks with glamour until the cotton covers the wicking holes. Also, there are three sections in the Trilogy, that are:

  1. One straight glass
  2. One short bubble glass
  3. One extended bubble glass

These three sections allow you to increase and decide the height of the tank and how you want it to look. And with the extended bubble glass, the Trilogy can hold 9ml of the e-juice.


  • Maximum capacity of 9ml
  • Excellent build quality
  • Attractive design
  • First-class airflow
  • Outstanding flavor


  • A huge tip of the drip (you can swap it with an 810-drip tip)


RTA stands for Rebuildable Tank Atomizer, a type of tank used for vaping, and it is best known as a mix of a refillable tank and a rebuildable tank to make your coils and wicks.

In general, they look very similar to a sub-ohm tank and offer the same e-juice and airflow control that you used to get from a refillable.

Although there are various reasons for using the RTA’s, the best two reasons are curating your coils with customization and getting the fantastic flavor without dripping it like an RDA.
