Innokin is very proud to introduce the iSub-B Tank - the sixth generation of internationally bestselling Innokin iSub Tanks.

The iSub-B is the first Innokin iSub tank powered by advanced Plex3D Coils with 3D mesh which use less power to deliver bigger flavors and clouds.  The Plex3D Coil’s advanced coil design with ‘Micro-Grooves’ increases the surface area and produces amazing flavor.  Plex3D Coils rapidly heat up and cool down faster than traditional coils, extending coil life; while the organic cotton and wood pulp wicking improves e-liquid coil flow and boosts flavor.

This tank is crafted with high quality stainless steel and features a rainbow tinted Pyrex glass.  The iSub-B twists to open and features automatic flood prevention when filling.  This tank is also compatible with all 510 threaded vaporizers and features a replaceable 510 resin drip tip.

Please note: This tank should NOT be used on any standard 3.7V battery. The resistance of this atomizer is too low for certain devices; meaning batteries with a standard voltage will think there is a short in the atomizer when really it is too low of a resistance for the battery to power. For any questions about what device would work best for you, please contact us directly!

Warning: You should NOT use sub ohm tanks on devices with hybrid top caps which are mainly found on mechanical devices. It is a top cap with no connection pin, meaning the atomizer makes direct contact with the battery. Using a sub ohm tank on a hybrid top cap could potentially result in catastrophic battery failure!
