Factors To Consider While Choosing The Best RTA Vapes

There are different types of rebuildable tank atomizers available in the market today that delivers altogether distinct experience. Therefore, to help you select the best rebuildable atomizer from the different types, here are some of the features you should compare and know about.

1. Airflow

Most atomizers available in the market features a bottom airflow system. But due to the leakage problems, many manufacturers have started making top airflow atomizers. The top airflow system routes the air towards the bottom or side of the coil via different methods. The top airflow RTA models prevent leakages of the e-liquid but the flavor and cloud production is not up to the expectations when compared to the RTAs with bottom airflow system. However, the newer RTA models with top airflow system have been delivering top-notch flavor without sacrificing cloud production.

2. Draw

The draw of the RTA vape tanks is also one of the most essential factors to consider while buying atomizers. It is vital to ascertain what kind of draw you like while vaping – mouth to lung or direct-lung. RTAs with a narrow and small number of airflow inlets or holes will deliver a mouth-to-lung draw. On the contrary, RTAs with multiple or larger air inlets facilitates significant cloud production that is channeled directly towards the lungs.

3. Coil

While searching for atomizers in the market you will come across single or dual-coil models. The vapor production to a great extent depends on the number of coils that your RTA has. Most of the single-coil RTA delivers mouth to lung draw and the cloud production is not that significant. On the contrary, dual-coils RTA delivers direct lung draw that facilitates better cloud production and flavor.

4. Price

If you are relatively new in the world of vaping then it is advisable to start with RTA for beginners. Such RTAs are considerably affordable when compared to the RTAs for professionals. You will take time to get a hang of building and installing the coil, so before you move to advanced RTAs it is advisable to use the RTAs for beginners. This way you will save a significant sum while you developing your vaping skills.

Advantages Of Using An RTA

The advantages of RTA are enormous when you compare it with the different types of vape tanks and atomizers available in the market.

  • Performance: When you perfectly build the coil and install it correctly, the RTAs will perform better than most of the sub-ohm and mouth-to-lung tanks that feature replaceable coil.
  • Freedom: One of the biggest advantages of using an RTA tank is that you can build your coils. Therefore, it allows you to save a significant sum on coil purchases. Also, you don’t have to rely on the manufacturer for the supplies of the coil head. On the other hand, sub-ohm tanks users have to rely on the coil heads sold by the company. Similarly, you can buy organic cotton at an affordable rate when compared to the kit sold by the RTA manufacturer.
  • Affordable: The entire roll of wire that you can purchase from the shop will allow you to make numerous coils at fraction of the cost. On the other hand, when compared to the rate of the entire roll of wire, you will hardly get one or two coils made by the RTA manufacturer. Besides this, you will never run out of the wire when in need as the entire roll of wire will last for months or years.
  • Capacity: It is because the capacity of holding the e-juice is better than the RDAs. While using RDAs you have to continuously pour the e-liquid in the atomizer, it is because they don’t have a large storage capacity. On the contrary, the RTAs have a great storing capacity which, therefore, allows you to enjoy vaping throughout the day. Secondly, most of the RTAs don’t leak. Whereas, the RDA atomizers are subjected to leakages.
  • Size: The size of the RTAs, ease of wicking, generation of massive clouds, etc. are some of the reasons why RTAs have become popular when compared to the RDAs.

Helpful Tips To Use RTAs

Here are some of the helpful tips and tricks that can help you make the most out of your RTA

  • If you have any doubts about your coil building skills and would like to try or practice it before you purchase your new RTA, then it is advisable to purchase the clearomizers that you are most-commonly available with RBA sections. With this, you can not only use the replaceable coils but you can also master the art of coil building and wicking.
  • If you have already purchased a rebuildable tank atomizer, ascertain where your tank has a separate RBA deck. If there’s an RBA deck, then you can replace the coil and use your atomizer.
  • You have to be very careful while building the coils as it should cover the air slots. It is because if your coil is short, the e-juice will drop on the air holds. If you have ever noticed a whistling or gurgling sound from your RTA, then this problem is due to the coil length.
  • To avoid flooding, ensure that the wick tail of the atomizer blocks the juice feed holes. With this, you will be able to enjoy the top-notch flavor.

Frequently Asked Questions

Q1. What Is An Ideal Capacity Of E-Juice Required For Rebuildable Tank Atomizers?

The capacity of an RTA vape tank is one of the biggest factors when it comes to the selection of an RTA tank. How much capacity an RTA vape tank should have is one of the frequently asked questions as every vaper has a different requirement. The frequency of your vaping can also help you ascertain whether you need a larger tank or not. Therefore, you should ascertain the volume of e-liquid which is consumed every day as you will refill the tank as and when it goes dry.

Q2. What Is The Difference Between Side Airflow, Top Airflow, And Bottom Airflow In An RTA?

As the name suggests, the RTAs with slide flow have air inlets on the sides. Whereas, in the case of atomizers with top airflow the air passes from the air holes that are located just above the coil. The bottom airflow atomizers have air inlets located at the bottom. The top airflow atomizers are popular because they prevent leakages of the e-liquid.

But the vapor production and flavor taste are not that great when compared to the side and bottom airflow atomizers. From the feedback and reviews of numerous vapers, they consider using atomizers with bottom airflow as they deliver the best flavor and cloud production. But many bottom flow atomizers are associated with leakage problems.

Q3. What Is The Importance Of Airflow In Vaping?

The airflow can determine the quality of your vaping experience and it plays a bigger role to play when it comes to the flavor and smoke. You can get more vapor, less flavor, and you can also enjoy a smooth vaping experience as the hit on your throat will be very less with increased airflow. On the other hand, you can experience more flavor and less flavor with a decreased airflow.

Besides this, you can get a harsh hit on your throat with a warmer and stronger draw. If the purpose of your vaping is to enjoy strong flavor then it is advisable to opt for a tighter airflow. On the contrary, if the purpose of your vaping is to enjoy the clouds then it is advisable to opt for a lesser airflow.

Q4. How Long Does The Coil Of RTAs Last?

The lifespan of your coil is dependent on numerous factors. Your frequency of vaping, the type of juice your use, at what wattage you vape, and others. One of the best things about the coils is that they can be cleaned and reused. But creating your coil is very easy and also very cheap, therefore many vapers prefer to change the coil frequently. The residue of the e-juice tends to build upon the coil which can transform the taste of the flavor. When you feel the change in flavor it is a signal to change your coil.

Q5. How Does An RTA Work?

It is one of the most frequently asked questions by beginners. All the RTAs have a similar working process. The key to getting the most out of your RTA depends on the coil or coils. Here the user will have to build a coil or more depending on the type of build deck or RTA. If you have a mouth-to-lung RTA then the atomizer will work fine on a single-coil. On the contrary, if you have a direct-lung RTA then you will require dual-coils. Once you have built your coil, install it back on the build deck of your RTA. Once the coil is in place it is time to wick it using cotton which you will have to place on the wicking holes.

The next step is to fill the e-juice or e-liquid in the tank. Allow the wicks to get soaked with the e-juice. While you draw a puff the air enters the tank via the air inlets and is channeled towards the coil which eventually generates clouds.
