The design of it is an increased surface area of the coil for great flavor and vapor production. The tank can withstand a power output of 55-65W. To get the full benefit of the ARC Coil, the Revvo Mini has a fully adjustable top airflow with 3 airflow slots. It also fills in the center of the tank, accessible directly through the mouthpiece, sits a spring-loaded filling tube.
