The VOOPOO UFORCE Sub-Ohm Tank presents a sensational performance tank with a superior quality chassis design featuring 3.5mL maximum capacity, quick vent channel, triple bottom airflow control, and the UFORCE OCC Coil System. The flagship creation from the manufacturers behind the popular DRAG and VOOPOO TOO series, the UFORCE Tank measures 24.6mm in diameter with elegant lines and grooves for a striking impression. The maximum juice capacity is 3.5mL, accessed via a sliding top-fill mechanism for convenient refills. The quick vent channel is implemented with a shorter chimney section than the standard Sub-Ohm Tank, allowing for rapid discharge of heat while maximizing flavor production. The new UFORCE OCC Coil is made for dynamic performances, featuring a 0.23ohm U4 Quadruple Coil with a wattage range of 50 to 120W and a 0.4ohm U2 Dual Coil with a range of 40 to 80W. Airflow enters the structure through three external airslots located at the bottom base, traveling upwards towards the atomizer chamber for a tremendous cloud delivery.
