This compact stainless-steel electronic cigarette allows both the voltage (VV mode) and the wattage (VW mode) to be adjusted. A display signals the charge status of the battery. The core of the eCom is the atomiser C2 head, which guarantees high vapour output. Users can adjust air flow with a designated small tool, controlling the vapour quality individually. A viewing panel in the tank helps to keep an eye on the liquid level so as to facilitate prompt refilling.
