What's the difference between RDA and RTA?
RTA's and RDA's are both types of RBA. The RTA (Rebuild-able Tank Atomizer) is a tank system and the RDA (Rebuild-able Drip Atomizer) is a dripper system. With re-build-ables, you "build" your own coil. In other words, you physically wrap a coil, attach it to the system and add a wick.
