An atomizer is the device that transforms the e-liquid into vapor. It bridges the gap between the battery power and the e-liquid itself, and is an essential part in transforming liquid into vapor.
When you activate your mod by pushing the button, the atomizer gently heats the liquid in your tank, and converts the e liquid into vapor.
Rebuildable drip atomizers (RDAs) and rebuildable tank atomizers (RTAs), though geared toward the more experienced vapor, are common for generating huge vape clouds and give more flavor to your e liquid making them the best atomizers for vaping. Each atomizer has its advantages depending on your level of vaping so it is important to shop based on your own skill level.
A vape tank contains a tank that holds e-liquid, which slowly depletes after each use and is replenished when empty. These devices contain coils that need to be replaced over time, by simply unscrewing the used coil and replacing it with a new one.
A rebuildable drip atomizer optimizes the vaping experience by allowing lower resistance and more battery power to generate, thus resulting in larger clouds. This system does not have a tank and requires a dripping method, where the e-juice is dripped directly on the atomizer coils and has to be replenished after every few puffs.
