UniTank Mini – Kanger Unitank Mini bottom coil tank is glue-free and fully disassemble-able! However the Uni Mini is eGo-style threaded and may need an adapter for some devices. There are two chambers in the tank, when the top cap is removed, the spring pops up and airflow and liquid is blocked from the bottom chamber (where the atomizer head is) to prevent leaks during a refill. The first Kanger Tank to be refillable from the top just like a Nova Tank. Watch the video below for more information and demonstration or click the link below to purchase the Unitank Mini now.
