0.15 Ohm Coil – What is it in Vaping?

Definition

A 0.15 ohmcoil is a low-resistance heating element used in sub-ohmvape tanks and rebuildable atomisers. Made from wires such as Kanthal, stainless steel or mesh, it measures 0.15 Ω on an ohm-meter and is designed to produce large, warm clouds of vapour when paired with high-wattage devices. By allowing more electrical current to pass from your 18650 battery, 21700 battery or 26650 battery, the coil heats e-liquid quickly, turning it into flavour-rich vapour. Ideal for direct-to-lung (DTL) vaping, a 0.15 ohm coil is the sweet spot for many Australian vapers chasing dense clouds without venturing into ultra-low builds.

Technical Details

Resistance is governed by wire thickness, material and coil length; a 0.15 ohm coil typically uses 26–30 gauge wire or a mesh strip with a large surface area. Operating range is 50–90 W for Kanthal and 60–110 W for mesh variants, though manufacturers list recommended wattage on the coil housing. Most are pressed into a 510 thread compatible replaceable cartridge, making installation tool-free. Variations include single-core Claptons, triple-core fused Claptons and mesh sheets, each offering different ramp-up times and flavour profiles. Temperature-control versions use stainless steel 316L or nickel, permitting regulated temperature limiting when paired with a TC-capable mod. Always verify that your device can safely fire down to 0.15 Ω—most modern regulated mods do, but older or protected tube mods may not.

Usage & Tips

• Prime the coil: drip e-liquid onto exposed cotton until saturated, then fill the tank and wait five minutes to prevent dry hits.
• Start low: begin at the bottom of the recommended wattage range and increase in 5 W increments until flavour peaks.
• Use high-VG juice: 70 VG / 30 PG or thicker wicks efficiently and produces bigger clouds; 0mg nicotine or low-nic strengths minimise Hit“>throat hit at high power.
• Stay hydrated: sub-ohm vaping can dehydrate; drink water to avoid vaper’s tongue and headaches.
• Change when flavour drops: heavy sweeteners can clog cotton within a week; replace the coil if you notice burnt taste or reduced vapour.

History & Context

When sub-ohm vaping emerged around 2012, adventurous Australian vapers rebuilt coils below 1 Ω on drippers to increase vapour. Mass-market 0.15 ohm factory coils appeared in 2015 with tanks like the Smok TFV4, bringing cloud-chasing to everyday users without the need for rebuilding. Today, 0.15 ohm mesh coils are ubiquitous, offering plug-and-play convenience while satisfying Australia’s flavour and cloud enthusiasts.
