Compact and discreet, this Innokin Axiom M21 Tank is designed with an e liquid capacity of 2ml. This meets the TPD specification for the UK and European market. With it’s wide-bore drip-tip, this tank is designed for mid power sub-ohm vaping in the 20 to 65 Watt power band. Flavour and cloud delivery go well beyond expectations from this low-profile, 22mm diameter atomizer!

Top filling is the preferred option for most modern sub-ohm tanks. The Innokin Axiom M21 tank comes with a simple, screw-down top cap which is easy to remove for filling. In this TPD version, the reservoir section is shortened to reduce the e juice capacity to 2ml.

You’ll find that the Axiom M21 tank comes fitted with a dual horizontal coil. This is the same coil arrangement used on many rebuildable dripping atomizers (RDAs). If you find that the 2ml tank drains too quickly, the tank’s conical drip-tip is easily wide enough to drip e juice directly onto the coil. Using the 0.5 Ohm horizontal coil as a dripper may be more convenient than regularly refilling the tank.

Along with the dual horizontal coil, you also get an alternative 0.65 Ohm vertical coil. This has the more usual, vertical coil and wicking arrangement. This coil vapes at higher power levels to produce incredibly dense clouds of vapour. The vertical coil also has a loose, airy draw which helps to boost cloud generation. Both Axiom coils should be vaped in variable wattage (VW) mode only.

At the base of the Axiom M21 tank there’s a triple-port airflow ring. This is another innovative feature on a compact sub-ohm tank. Many vapers find that the Axiom coils are precision designed to operate at their best with wide-open airflow. You may prefer to use the adjustable airflow ring to find your own sweet-spot for flavour from this impressive mid-power tank.

The Innokin Axiom M21 Tank comes in traditional Black or Stainless Steel.

Note: E Juice isn’t provided with this TPD compliant tank. Please check-out the incredible range of e juices on offer in our E Liquid pages, click here for link.
