SMOK TFV8 Baby V2 tank has a bulb-shaped juice reservoir that can store 5ml of E-Liquid. Refills of the atomizer is performed by engaging a lock button on the top cap which rotates to access an e-liquid slot. The gasket on the fill port is located on the bottom to ensure that refills are leak proof. An upgraded airflow system at the bottom is built with a total of three air inlets. Airflow works in combination with a 16mm Delrin drip tip to resist heat and improve flavor and vapor. The tank has many coil head options, two of them are included in the kit. One is the 0.17ohm Baby V2 A1 that works from 90-140W but is recommended at 110-130W. The other is a 0.2ohm Baby V2 A2. It is said to produce huge vapor and works in the range of 85-105W.
