Description
Innokin AXIOM M21 coils are the replacement heads for the Innokin AXIOM M21 tank, found in the Kroma-A AXIOM kit. They use a bottom vertical coil design with Kanthal wire and organic cotton, and you can choose 0.5 or 0.65 ohm. The AXIOM M21 coils suit relaxed direct-to-lung vaping with good flavour.
Key features
- Resistances: 0.65, 0.5 ohm
- Design: bottom vertical coil (BVC)
- Wire: Kanthal
- Wick: organic cotton
- Fits: Innokin AXIOM M21 tank, Kroma-A AXIOM kit
Which resistance?
- 0.65 ohm: slightly lower power, a little more flavour and less liquid use
- 0.5 ohm: a bit warmer and more vapour, still at modest wattage
Both suit a loose restricted or open lung draw rather than tight MTL. They are a good step up for vapers moving from a pod kit to a small sub-ohm tank, as they run at lower wattage than most mesh coils.
E-liquid and nicotine
Use a 50/50 or higher VG liquid with these coils. Because they produce more vapour than MTL heads, keep nicotine low, around 3mg to 6mg. A shortfill such as Hayati Pro 100ml 70/30 with a nicotine shot works well.
Priming and lifespan
Wet the cotton through the side holes before fitting, then fill the tank and wait five to ten minutes. Start at the lower end of the coil's wattage. Most AXIOM M21 coils last one to three weeks, depending on how much you vape.
