0.1 Ohm Coil – What is it in Vaping?

0.1 Ohm Coil – Comprehensive Glossary Entry

Definition

A 0.1 OhmCoil (pronounced “zero-point-one ohm”) is a low-resistance heating element used in high-performance vape tanks and rebuildable atomisers. By allowing more electrical current to pass from your 510 Thread device, it instantly heats large amounts of e-liquid into dense, flavour-rich vapour. Designed for advanced vapers, this coil maximises cloud production and intense flavour, but it demands powerful batteries—typically 18650, 21700, or 26650 cells—and high-wattage mods capable of 75–150 W.

Technical Details

How it Works

Ohm’s law governs the coil: at 0.1 Ω, a fresh 4.2 V battery draws 42 A and produces ~176 W. Advanced chipsets step-down voltage to safer levels (e.g., 3.0–3.5 V) yielding 90–120 W. Most 0.1 ohm coils utilise:

  • Mesh strips or octuple fused Claptons for even heat distribution.
  • SS316L, Ni80 or Kanthal A1wire rated to 200 °C+.
  • Cotton“>Organic cotton or wood-pulp wicking for rapid saturation.

Variations

  • Pre-built stock coils (e.g., SMOK TFV18, Vaporesso GTi)
  • Rebuildable options: 0.1 Ω single coil (3 mm ID, 5 wraps) or dual 0.2 Ω coils in parallel.
  • Temperature Control variants using SS316L for dry-hit protection.

Usage & Tips

  • Priming:Drip e-liquid onto cotton until saturated; start at 60 W and increase gradually.
  • Battery safety: Use married high-drain 30 A cells; check wraps and insulators before every session.
  • Common issues:Burnt taste = insufficient wattage or 0mg nicotine high-VG juice too thick—thin with 10% PG or raise wattage 5 W increments.
  • Cleaning: Light dry-burn to glowing orange, then rinse; replace every 7–14 days or when flavour drops.

History & Context

The 0.1 ohm coil emerged circa 2014 when sub-ohmvaping shifted from hobbyist mechs to regulated 150 W box mods. Australian vapers embraced it after the 2021 import regulations, driving demand for high-capacity 21700 devices and safer battery technologies.
