Nick Coil – What is it in Vaping?

Definition

A Nick Coil is a pre-built or hand-wrapped heating element used in rebuildable atomisers and pod systems that is made from Wire“>nichrome wire (NiCr). Its purpose is to heat nicotine-containing e-liquid into vapour while delivering a smooth Hit“>throat hit. Nick Coils are popular among Australian vapers who prefer fast ramp-up times and consistent performance with both nicotine salt (nic salt) and freebase nicotine e-liquids.

Technical Details

How It Works

Electric current from your Battery“>NiMH battery or lithium-ion cell flows through the nichrome wire, which has moderate resistance and high oxidationtolerance. The wire heats to 180–250 °C, instantly vaporising the e-liquid absorbed by the surrounding cottonwick.

Specifications & Variations

  • Common Gauges: 24–32 AWG
  • Resistance Range: 0.15 Ω – 1.2 Ω
  • Build Styles: Micro, macro, spaced, Clapton, fused Clapton, and mesh strips
  • Alloy Ratios: Ni80 (80 % nickel, 20 % chromium) and Ni90 (90 % nickel, 10 % chromium) for even lower resistance

Usage & Tips

Practical Advice

  • Prime the wick thoroughly with nic salt or freebase e-liquid before first use.
  • Start at 10 W below the coil’s rated wattage and increase gradually to avoid dry hits.
  • Check for hot-spots with a dry burn at low wattage; glowing should be even from centre outward.
  • Replace every 7–14 days or when flavour drops, especially when using sweetened nic salt juices.
  • Always lock your device or remove the NiMH battery when re-wicking to prevent accidental firing.

History & Context

Nichrome wire entered the vaping scene in 2013 as an alternative to kanthal, prized for its rapid heat-up. The term “Nick Coil” gained traction in Australian forums around 2017 alongside the rise of nicotine salt pods, offering smoother throat hits at higher nic strengths without the metallic aftertaste of older alloys.
