R-Kiss Kit by Smok
KISS, which means Keep It Simple and Stupid, you can feel this from every detail of the kit. Simple two-color combination endows this mod modern style; 200W max output power can help to offer strong vapor effect; and the newly designed user interface is also a simpler one, from which you can get detailed vaping information.
The included TFV-Mini V2 tank has three wider airflow slots, two new coils -- Mini V2 A1 and Mini V2 A2, all of which are perfect choices for max vapor.
When it comes to two - battery powered box mod, especially 18650 battery, you may remind of those big and heavy ones, while R-Kiss is different, it is smaller and lighter, which could satisfy your needs for both strong power and portable size, with 77mm height, 44mm width, it is the smallest two--18650 battery box mod worldwide.
