How Sub-Ohm Vape Kits Work
A sub-ohm vape kit is any kit whose coil resistance sits below 1.0 ohm. By Ohm's law that lower resistance pulls more current and heats a larger mesh coil faster, vaporising far more e-liquid per draw than a standard MTL pod coil. The result is the warm, dense direct-to-lung (DTL) hit and big clouds sub-ohm vaping is known for.
That power is why a sub-ohm vape kit pairs with high VG shortfill (70/30 or 80/20) at 0mg or 3mg freebase nicotine rather than nic salts, which hit too hard at sub-ohm wattages. Each kit is a complete setup - mod, sub-ohm tank, fitted coil and USB-C cable - so it works straight out of the box.
Choosing the Best Sub-Ohm Vape Kit
The range spans compact, affordable starter kits and pod-style sub-ohm vapes up to 200W high-wattage cloud machines. To pick the best one for you, focus on three things:
- Power - around 50W to 80W is plenty for flavour, 100W and up for big clouds, and 200W high-wattage kits for cloud competition. Whatever the mod reaches, stay inside your coil's printed wattage range.
- Battery - internal-cell kits charge over USB-C and are simplest and lightest; removable 18650 or 21700 kits give the longest battery life and let you swap in charged spares.
- Build - rugged IP-rated kits suit outdoor and work use, compact kits suit pocket carry. Every kit comes with a matched sub-ohm tank, fitted coil and adjustable airflow, so it works straight out of the box.
If you already own a tank and just need the device, our vape mods collection covers standalone mods. When a coil wears out you fit a fresh one from the sub-ohm coils collection, and for more capacity see the sub-ohm tanks range.
Sub-Ohm Coil Wattage Guide
Every sub-ohm coil has a recommended wattage range printed on it. Stay in that band for the best flavour and coil life - too high burns the cotton out in days, too low leaves the flavour muted and cool.
Coil Resistance |
Typical Wattage |

Best For |
0.15 ohm |
60W to 80W |

Give a fresh coil five to ten minutes to soak after filling, then start low and work up to find the sweet spot.
Sub-Ohm vs MTL Vaping
Sub-ohm vaping is the direct-to-lung (DTL) style - an open, airy draw that makes big clouds and intense flavour, paired with high VG shortfill e-liquid at 0mg or 3mg freebase, never nic salts. MTL (mouth-to-lung) is the tighter, cigarette-style draw most ex-smokers prefer, served by low-wattage pod kits instead.
If you have vaped a while and want more vapour and flavour, a sub-ohm vape kit is the step up; if you want a discreet, cigarette-like vape, an MTL pod kit is the better fit. For a full breakdown of each style, read our guide to vaping styles.
