best RTA

An RTA refers to a rebuildable tank atomizer that consists of a tank section eliminating the manual feeding of the e-liquid. RTAs allow users to regulate the airflow with the use of a ring. Most include additional features that distinguish how the airflow is regulated and how air hits the coils providing a wide variety for vapers.

Best Rebuildable Tank Atomizers

How does it function

An RTA is built to function by creating a coil, which is then installed in the build deck atomizer. The ring is then wicked with cotton lacing the cottontails in the wicking holes of the build decks. One then fills the tank with e-liquid and gives it time for the cotton to saturate with the wicking channels’ juice. Thus, when inhaled air enters through airflow holes and channeled to the inside of the build deck, it hits the coil on its way to the chimney and finally to the drip tip.

Types of RTAs

i. Bottom vs. top airflow

Bottom airflow RTAs focus on flavor delivery but is faulted for the leaking problems that make it wasteful and expensive. Top airflow uses side and top mechanisms to deliver the liquid to the device but has been widely criticized for its flavor quality. The latest top airflow designs are slowly correcting this, but the two choices offer a variety to choose their favorite.


The draw of an atomizer is primarily characterized by the number of airflows and their sizes. Atomizers with narrow and fewer air holes produce a mouth to lung draw, while multiple large holes allow for more vapor production leading to direct lung inhalation.

iii. Single vs. dual coil

The number of RTA coils directly influences the amount of vapor produced. Thus, single-coil RTAs supported MTL and restricted DL draws while dual coils allowed for more vapor production, making them DL draws. Some dual coils come with airflow rings that allow for proper regulation giving them MTL capabilities.

Advantages of RTAs

  • High performance when properly built
  • Saves money on coil purchases as the wrapping of coils makes them last longer.
  • Uses tiny organic cotton that may last up to a year
  • It has a large capacity to hold the e-juice, allowing one to go for long before requiring a refill.
  • Most do not leak if left lying on the side or upside down, making them ideal for movement and preventing unnecessary leakage, as this only occurs when they are upright and not correctly screwed.
  • Easy to wick and more compact, offering an enormous capacity to their users.

Tips and tricks for RTA

  • Keep the cotton fluffy as a densely packed cotton will not soak the e-juice entirely compared to a loosely packed one. Fluffy cotton allows the wicked space to make it function correctly.
  • Use enough cotton to ensure the wick can function effectively.
  • Avoid blocking the juice channels with the cotton; ensure it sits properly on the juice channel to absorb the liquid.
  • Keep the cotton away from the airflow to prevent leaking of the juice.
  • Prime the wicks before refilling and vaping to maximize the juice and prevent dry hits.
