Atomizer- A coil that when engaged produces enough heat for ionization to occur with some materials.
Clearomizer- Atomizer inside of a tank.
Cartomizer- Atomizer inside of polyfill wick, inside of a tube.
RBA- Rebuildable Atomizer.
RDA- Rebuildable Dripping Atomizer.
I'm just offering those for terminology. I'd advise you to find other mediums first, and get familiar with
vaping and basic concepts of electricity before pursuing RBA's.
There are also cartomizer tanks, which I primarily use. I've found cartomizers to offer ME more flavor and a denser cloud of vapor. They can also withstand higher voltages from the amount of liquid that stays around the coil with a well functioning cartomizer. Clearomizers give me a milkier, looser cloud, and they can't withstand near the same amount of Power as a cartomizer can.
Whatever delivery method you start out with, I highly suggest getting a drip atomizer. I love them. Not only do they produce great vapor and flavor, but they are the best way to try new liquids, or if you just feel in the mood for a wide variety of flavors or liquid ratios.
