Each type of Best RTA can provide a completely unique experience. Here are the main features to look at when choosing the perfect one for you.
Bottom airflow vs top airflow
Most RTAs will implement a bottom airflow system. Due to potential leaking, companies have also been designing top-airflow systems that channel the air to the side or bottom of the coils through different mechanisms. While these designs are more leak resistant, they sometimes end up sacrificing flavor, although newer top-airflow atomizers have been performing much better in the flavor department.
MTL vs DL
The draw of the atomizer is also an important categorization for RTAs. Atomizers that come with a small number of narrow airflow holes will produce a mouth-to-lung draw, while larger airflow slots or multiple holes will allow more vapor production and are geared towards direct-lung inhales.
Tips and tricks for RTAs
Here are a few helpful tips to be aware of when using an RTA:
If you are unsure of your building skills and would like to see how you fare before you purchase a new atomizer, search for clearomizers that come with an RBA section. This way you will be able to use replaceable coils while practicing your building and wicking game. If you already own a tank that takes replaceable coils, check to see if there is an RBA deck available for it. In some cases, the RBA section is not included in the retail version, but can be purchased separately.
When building on an RTA (or an RBA) make sure the coils span across the air slots, especially on a bottom airflow atomizer. If the coil length is too short, it allows the wicks to drip e-liquid into the air holes, which can lead to gurgling and even flooding.
Another trick to prevent flooding is to be sure the wicks do not allow e-liquid to flow past them onto the deck. The wick tails must adequately block the juice feeding slots or holes. However, if the RTA begins to dry hit, then the user has too much wick blocking or hindering juice flow. Finding the perfect balance is key to achieving top performance.
Most modern RTAs allow the user to access the build deck at any time for re-wicking and are highly recommended for beginners and reluctant builders. Finally, be sure not to overfill the RTA. Leaving an air bubble allows juice to adequately flow to the wicks and exchange air for vaporized liquid.
