A redesigned Subtank with top fill capability and fantastic new coil options, Kanger Toptank Mini is a highly engineered, beautifully styled tank, whether it’s part of the new Kanger Topbox kit or on any high-performance mod. With increased airflow and juice capacity over the Subtank Mini, the new Toptank is a true upgrade, not just a Subtank with a new roof. The 22mm Kanger Toptank holds an impressive 4mL of your favorite liquid, and it now accepts Claption and Stainless Steel coils that can really breathe under improved airflow. The first generation Subtank coils also fit the Toptank and work better than ever. Best of all, the Toptank’s entire topcap unscrews from threading inside the chimney unit, leaving ample room for filling from even wide-bore drippers, and the cap screws back on securely and leak-free.
