What is the difference between a Tank, RDA, RDTA and RTA?


A tank is essentially an atomizer that is placed inside of a tank filled with e-liquid that pushes the liquid through to a wick that feeds the juice up through your e-cigarette and turns it into vapor. Once upon a time, this process could be painful for some vapers, especially those who vape a lot, since wicks didn’t always move e-juice quickly enough. Tanks have evolved, though, and are now able to keep e-juice moving more efficiently.


RTA's and RDA's are both types of RBA (ReBuildable Atomizer) The RTA (Rebuildable Tank Atomizer) is a tank system and the RDA (Rebuildable Drip Atomizer) is a dripper system. With rebuildables, you "build" your own coil. In other words, you physically wrap a coil, attach it to the system and add a wick. There are many different builds, each one depending on the RBA type and the desired vape the user wishes to achieve. RDTA is the best of both worlds, it has the convenience of a tank (juice capacity) and the flavour of a RDA, this makes it the most versatile atomizer on the market.
