A vape tank is a component of a vaping device that holds e-liquid, which is vaporized to create inhalable vapor. It typically consists of a reservoir for the liquid, a coil that heats the liquid, and a mouthpiece for inhalation. Vape tanks come in various sizes and designs, allowing users to choose based on their preferences for capacity and style. Most vape tanks use a system called sub-ohm or mouth-to-lung to deliver different vaping experiences. They can be made from materials like glass or stainless steel and often feature adjustable airflow to control the amount of vapor produced. Regular maintenance, such as cleaning and replacing coils, is essential for optimal performance.
