RDA ::: Rebuildable Dripping Atomizer
RDA / RDAs are atomizers where the e-juice is dripped directly onto the coil and wick. The common nicotine strength of e-liquids used in RDA’s is 3 mg and 6 mg. Also, Liquids used in RDA’s tend to have more vegetable glycerin. They typically consist only of an atomizer building deck, commonly with three posts with holes drilled in them, which can accept one or more coils. The user needs to manually keep the atomizer wet by dripping liquid on the bare wick and coil assembly. Kanthal wire is commonly used in RDA’s in addition to nickel or titanium wire for temperature control. RDA’s heating coil can accept much more power than RTA’s, which lead to the difference of their atomization effect on the e-liquid. The RDA usually comes with a sub ohm coil and operates at a high power, which can generate massive amounts of heat instantaneously, and then vaporize a lot of e-liquid. While RTA is somewhat humble in this aspect.
