Innokin iSub-B Sub-Ohm Vape Tank

Introducing the 6th generation of tanks from Innokin's best selling line, the iSub B! Innokin has redesigned this tank with the promise of higher performance with lower wattage. This version of the iSub is a good bit shorter as well as wider, making it more low-profile so that it looks a lot better on box mod vapes. The iSub B is created from high quality stainless steel and has rainbow tinted pyrex glass.

This sub-ohm vape tank is a twist-to-open top fill and also features "automatic coil flooding prevention" when filling via the spring loaded chimney, which cuts off juice flow to your coil upon opening the tank. Innokin also made the iSub-B with "four point" adjustable airflow, which allows for a nice open draw. The drip tip on the iSub-B has a nice and thick resin wide-bore drip tip on it, but you can easily replace this with your favorite 510-sized tips.

Staff Recommendation:
Of the 9 different coil options that the iSub-B has to offer, I like the new Plex3D coil the best out of all of them. These coils are made from a new type of mesh that is 3D with capillary wicking grooves in the coil. This produces more flavor and vapor while still keeping the power level relatively low. These coils are wicked with organic cotton and wood pulp, giving the coil a much cleaner flavor. These coils run 30 to 55 Watts, making it a good option as a medium range sub-ohm tank. - Nic

How To Prime Your Innokin iSub B Coils

  • Turn your tank upside down and unscrew the base of the tank.
  • Remove your coil. The coil can be removed by gripping the threaded 510 of the coil and pulling upward. The coil should just slide right out of the tank.
  • Prime your coil by adding vape juice to the cotton wick from either the top or the sides until all of the cotton looks saturated.
  • If you over-primed, you can use a tissue or paper towel to wrap the coil, shake a few times, and then wipe off any excess liquid from the outside.
  • Install your freshly primed coil by pushing the coil back into the tank ensuring that the flat metal sides of the coil fit between the raised metal guides on the tank itself.
  • Screw the base of your iSub-B onto the rest of the tank.
  • You are now ready to fill the iSub-B!

How To Fill Your Innokin iSub B Tank

  • Push down slightly on the metal lid of the tank and turn counterclockwise to open. The metal lid of the tank with attached drip tip should come off all the way.
  • Fill the tank by placing the tip of your bottle between the glass and the metal chimney (this is your airflow so you don't want to flood that with liquid)
  • Fill the tank to the top.
  • Screw the lid back onto the tank by screwing the cap on clockwise.
  • Set your device to the lowest recommended wattage or temperature in order to 'break in' your coil.
  • You can turn up your wattage a bit after you've vaped on the coil for at least an hour.
  • Vape and enjoy!
