The Kraken v2 is a sub-ohm tank and it's pretty slick. It uses Kangertech's Subtank coils or Subtank RBA deck, features a quick-release top cap for ultra-fast filling, holds 2.5ml of e-liquid, uses a glass tank, and features airflow control. If you love the flavor of the Subtank but want a warmer, richer vape, you owe it yourself to check out the Kraken v2.
