Aspire Revvo Sub-Ohm Tank is an innovative 2ml capacity vaping tank. The Aspire Revvo Sub-Ohm features an adjustable side airflow and uses a new “stove top” style ARC (Aspire Radial Coil) coil. The ARC is designed to soak from within the tank, please tilt the tank as to ensure ARC saturation. Filling your new Aspire Revvo sub-ohm tank is another of Aspire’s innovative designs, and it couldn’t be simpler. In the centre of the tank, accessible directly through the mouthpiece, sits a spring loaded filling tube. The spring of the tube is soft enough to allow even slight pressure from almost any type of bottle/glass dropper to open it, but strong enough to create a leak proof seal when released after filling and the strong Pyrex glass tank allows you to see at a glance the amount of e-liquid in the tank. No one has yet produced such an innovative replaceable coil for an tank until now, except of course, Aspire. The fantastic all new coil design, the ARC, ‘Aspire Radial Coil’, sits horizontally in the tank similar to a ‘stove-top’ design. Of course the real trick in the design is the increased surface area of the coil for great flavor and great vapor production rated at 0.10-0.16ohm using Kanthal AF wire. Fitting or replacing the new Aspire ‘radial’ coil has also been made almost too easy for words. Simply unscrew the mouthpiece/top-cap, unscrew the coil mounting screw, remove the used coil, drop another coil over the filling tube, ensure that it is sitting flush with the body of the tank around all sides, screw on the coil mounting screw and the mouthpiece/top-cap and that’s it! It can even be changed with e-liquid still in the tank. As an added function, the conical coil mounting screw also acts as a spit-back protector, just in case.
