The A9 Rebuildable Dripping Atomizer (RDA for short) from Kumiho is recommended for advanced users only.
Two distinct features make it different from other RDAs.
1. Adjustable Airflow System, there is one fixed-size hole on the lower stainless tube and two holes in different sizes on the upper stainless tube. Adjusting the location of the two holes on upper tube is used to control the airflow.
2. Dual coil. The A9 RDA comes fully assembled with a 2.4ohm dual coil so it can produce more vapor and forward ejuice more easily to the heating coil than regular RDAs.
Besides this, the A9 RDA shares the same features as other RDAs.
It has a removable and changeable coil which resistance is easily changed by adjusting the length of coil.
