RDA stands for Rebuildable Dripping Atomizer. The atomizer itself is rebuildable so you can tailor the coil build to suit your vape style or desired output. You need to regularly top up (Drip) with E-liquid.
These are chosen for their precise control and enhanced ability to produce rich flavoursome clouds. Compatible with almost all mods with a 510 connection, best paired with higher wattage devices.
