VooPoo introduces the UFORCE Sub-ohm Tank, a sub-ohm tank with an upgraded venting system and triple airflow slots for a balanced and tasty inhale. The UFORCE utilizes a quick vent channel to produce huge vapor without heating the tank up too rapidly. The shorter path from the air intake to the outtake will rapidly discharge the heat, users will enjoy great flavors and tremendous clouds without the drip tip over heating. The UFORCE utilizes the U2 0.4 ohm coil rated at 40 to 80W and best at 55 to 65W and the UForce U4 0.23 ohm coil rated at 50 to 120W and best at 60 to 80W. The juice enters the UForce through a 7mm by 3mm fill port and can accommodate 3.5ml of E-Liquid. With amazing flavor and balanced air channels, the UFORCE Sub-Ohm Tank goes great with any mods.
