1.8 Ohm Coil – What is it in Vaping?

Definition

A 1.8 OhmCoil is a replaceable heating element inside a vapetank or pod that has an electrical resistance of 1.8 ohms. Its job is to turn e-liquid into vapour when power from the Thread“>510 thread device is applied. The higher resistance means it runs at lower wattage, producing a cooler, tighter “mouth-to-lung” draw that closely mimics smoking a cigarette—ideal for new Australian vapers or anyone using Nicotine“>0mg nicotine or high-nicotine salts.

Technical Details

Constructed from kanthal, nichrome or stainless-steel wire wrapped around Cotton“>organic cotton or Wick“>ceramic wick, the 1.8 Ω coil typically operates between 7–13 W. Most are designed for 510 thread clearomisers and pods with restricted airflow. Coil diameter ranges from 1.2 mm to 2.0 mm, yielding a surface area that balances flavour and longevity. Variations include vertical or horizontal wire orientation, mesh strips at 1.8 Ω for faster ramp-up, and Ni80 or SS316L temperature-control versions. Compatible with both fixed-voltage devices and single-Battery“>18650 battery mods in variable-wattage mode.

Usage & Tips

• Priming:Drip 3–4 drops of e-liquid onto the cotton before installation to prevent dry hits.
• Wattage: Start at 7 W, increase by 0.5 W until flavour peaks without burning.
• Common Issues:Gurgling usually means flooding—blow gently through the mouthpiece while firing for one second. Burnt taste indicates the coil is spent; replace every 7–14 days.
• Safety: Never exceed 15 W; check that your 18650 battery or integrated cell can supply at least 5 A continuous discharge.

History & Context

The 1.8 ohm coil debuted in the early 2010s with cig-a-like clearomisers such as the CE4. As sub-ohmcloud chasing rose, high-resistance coils became the go-to for discreet, nicotine-salt vaping. Today they remain a staple in Australian pod kits and starter bundles, bridging smokers and advanced rebuilders alike.
