Sub Ohm Vape Kit
What Is a Sub-Ohm Vape Kit?
A sub-ohm vape kit is a vaping device that uses coils with a resistance below 1.0 ohm to produce larger amounts of vapour and enhanced flavour. The kits typically combine a battery, tank, and low-resistance coil into a single setup.
Mesh coils and adjustable wattage settings are common across modern sub-ohm kits, giving users more control over flavour and vapour production. The lower coil resistance allows the device to operate at higher wattages, creating warmer vapour and increased cloud production compared to standard vape kits.
High-VG e-liquids are used with sub-ohm kits because thicker e-liquids perform best with the airflow and power output these devices provide. Many kits feature adjustable airflow controls, giving users greater control over vapour production and flavour intensity.
While MTL (Mouth-to-Lung) devices focus on a tighter draw and lower power output, sub-ohm vape kits are designed primarily for DTL vaping, making them a popular choice for vapers seeking increased vapour production, flavour intensity, and device customisation.
What Does a Sub-Ohm Vape Kit Consist Of?
A sub-ohm vape kit consists of several components that work together to support DTL vaping and high-performance vapour production:
- Vape Mod (Battery) – The main power unit of the device. It houses either a built-in battery or removable 18650 and 21700 cells, allowing users to adjust wattage and other settings.
- Sub-Ohm Tank or Pod – The e-liquid reservoir that connects to the device. Most tanks are made from stainless steel and glass or durable PCTG plastic and feature wide airflow channels to support increased vapour production.
- Sub-Ohm Coil – A sub-ohm coil has a resistance below 1.0 ohm, while higher-resistance coils are often used for MTL vaping. Many sub-ohm coils use mesh technology and large cotton wicks to absorb high-VG e-liquid efficiently.
- Drip Tip (Mouthpiece) – A wider-bore mouthpiece positioned at the top of the tank, designed to accommodate the larger volume of vapour produced during DTL vaping.
- Accessories – Many kits include practical extras such as spare O-rings, replacement glass sections, spare coils, and a USB-C charging cable.
Each component plays a different role, but together they allow the device to handle higher wattages and thicker e-liquids more effectively than a standard vape setup.
What Is the Difference Between Sub-Ohm and MTL?
Sub-ohm and MTL vaping are designed for different vaping styles. A sub-ohm vape uses coils below 1.0 ohm and supports direct-to-lung (DTL) vaping, while MTL devices use coils between 0.6Ω and 1.8Ω depending on airflow and power settings. As a result, sub-ohm kits operate at higher wattage levels and produce more vapour, whereas MTL devices use lower wattage and focus on nicotine delivery with a tighter draw.
| Feature | Sub-Ohm Vaping | MTL Vaping |
|---|---|---|
| Inhalation Style | Direct-to-lung (DTL) vape | Mouth-to-lung (MTL) |
| Coil Resistance | Below 1.0Ω | 0.6Ω-1.8Ω |
| Wattage | Higher wattage output | Lower wattage output |
| Airflow | Open airflow | Restricted airflow |
| Vapour Production | Large vapour clouds | Smaller vapour clouds |
| Nicotine Strength | Usually lower strengths | Often higher strengths |
| E-Liquid Type | High-VG e-liquid | 50/50 VG/PG e-liquid |
A direct-to-lung vape is often preferred by users looking for increased flavour and vapour production, while MTL devices are widely chosen by vapers seeking a more discreet and cigarette-like experience.
How to Choose a Sub-Ohm Vape Kit
Choosing a sub-ohm vape kit comes down to several key factors, including power output, battery type, coil resistance, and ease of use. The best option depends on your vaping style, wattage range, and level of experience.
Power Output: 100W vs 200W
Power output affects vapour production, battery consumption, and coil compatibility. While some devices can reach 200W, most users achieve excellent performance with considerably lower settings.
| Feature | 100W Kit | 200W Kit |
|---|---|---|
| User Type | Everyday DTL Vaper | Advanced DTL User |
| Battery Setup | Single-Battery Kit | Dual-Battery Kit |
| Typical Coil Range | 0.15-0.4 Ohm | 0.1-0.2 Ohm |
| Wattage | 40W-80W | 80W-150W+ |
| Device Size | More Compact | Larger |
| Battery Efficiency | Higher | Lower |
| Vapour Production | High | Very High |
Many sub-ohm users rarely need to exceed 80W. Battery life often has a bigger impact on day-to-day use than maximum wattage. A 200W kit is usually preferred by users seeking maximum vapour production and extensive customisation.
Battery Type: Built-In vs External
Battery choice influences convenience, portability, and long-term flexibility. Built-in batteries are straightforward to use and recharge through USB-C charging ports. Capacities range from 2500mAh to 5000mAh.
External battery devices use removable 18650 or 21700 cells and are available in single-cell and dual-cell configurations. These kits often provide greater power output and allow batteries to be replaced when needed. Built-in battery devices are commonly chosen by beginners, while external battery kits appeal to users looking for longer-term versatility.
Coil Resistance and Mesh Coils
Coil resistance plays a major role in determining wattage requirements and vaping performance. A sub-ohm coil has a resistance below 1.0 ohm, while MTL coils range from 0.6Ω to 1.8Ω depending on the device and airflow settings.
| Coil Type | Resistance Range | Typical Vaping Style |
|---|---|---|
| MTL Coil | 0.6Ω-1.8Ω | MTL |
| RDL Coil | 0.4Ω-0.9Ω | Restricted Direct Lung |
| Sub-Ohm Coil | Below 1.0Ω | DTL |
Mesh coils have become common in sub-ohm devices because they heat e-liquid more evenly and tend to maintain flavour consistency throughout the coil lifespan.
Best Sub-Ohm Kits for Beginners
For beginners, user-friendly sub-ohm kits are often the best place to start. Built-in batteries, automatic coil recognition, and mesh coils help reduce the learning curve and make the device easier to use from day one.
Many beginner devices also feature single-button operation, top-fill tanks, and USB-C charging, reducing the need for manual adjustments. If you are new to sub-ohm vaping, a compact kit with a built-in battery, smart wattage settings, and mesh coil support is often the easiest place to start.
Best E-Liquid for Sub-Ohm Kits
The best e-liquid for sub-ohm kits is a high-VG blend formulated for low-resistance coils. Sub-ohm devices perform best with 70/30 VG/PG e-liquids, as the thicker consistency wicks effectively and supports smooth vapour production. Some vapers prefer 80/20 blends for even denser clouds. High-VG formulations pair well with mesh coils and other low-resistance coil types, helping to enhance flavour delivery while producing large amounts of vapour.
Not every e-liquid is suited to sub-ohm vaping. Thicker e-liquids are ideal because they wick efficiently through larger coil ports and support the increased vapour production these devices are known for. When choosing a sub-ohm e-liquid, consider the following factors:
- VG/PG Ratio – High-VG blends such as 70/30 and 80/20 are well suited for sub-ohm vaping.
- Nicotine Strength – Lower nicotine levels are preferred due to the increased vapour output of sub-ohm devices.
- E-Liquid Format – Shortfills are a popular choice and can be customised with nic shots to achieve the desired nicotine strength.
- Coil Compatibility – High-VG liquids are best suited to mesh coils and other sub-ohm coil types.
A 70/30 shortfill mixed to 3mg or 6mg remains one of the most common setups among sub-ohm users.
What VG/PG Ratio Is Best for Sub-Ohm?
A high VG/PG ratio is best for sub-ohm vaping. Thicker e-liquids are a better match for sub-ohm coils, which is why 70/30 VG/PG remains the most widely recommended ratio. For users focused on cloud production, 80/20 VG/PG can also perform well. High-VG e-liquids wick efficiently through sub-ohm coil designs and help produce the dense vapour associated with DTL vaping.
What Nicotine Strength Suits Sub-Ohm Kits?
Lower nicotine strengths are commonly paired with sub-ohm devices due to their ability to produce large amounts of vapour with every puff.
- 3mg Nicotine – The most common choice for everyday sub-ohm vaping.
- 6mg Nicotine – Suitable for users who prefer a slightly higher nicotine level.
- Shortfills with Nic Shots – Nicotine-free shortfills can be mixed with nic shots to create a final strength of 3mg or 6mg.
- 20mg/ml Nicotine Salts – Usually intended for MTL devices rather than high-powered sub-ohm kits.
The ideal strength varies from person to person, but most sub-ohm users stay within the 3mg to 6mg range.
How Do You Maintain a Sub-Ohm Vape Kit?
Maintaining a sub-ohm vape kit involves regular coil care, tank cleaning, battery management, and proper e-liquid use. To keep performance consistent, it is important to prime every new sub-ohm coil before use, operate the device within the ideal wattage range, and replace coils when flavour or vapour production starts to decline.
Routine maintenance also includes cleaning the tank, drip tip, and airflow system to remove condensation and e-liquid residue. While some users attempt to clean a sub-ohm coil, cleaning may only remove surface build-up and cannot restore burnt cotton. In most cases, replacing the coil provides the best results. Regular maintenance will not make a coil last forever, but it can help keep flavour consistent and reduce common issues such as leaking or premature coil failure.
How to Prime a New Sub-Ohm Coil
Priming a new sub-ohm coil before first use helps the cotton wick absorb e-liquid properly. Taking a few minutes to prepare the coil can improve flavour, extend coil life, and reduce the risk of dry hits or burnt cotton.
Step 1: Apply E-Liquid to the Coil
Add a few drops of e-liquid directly onto the exposed cotton ports and centre wick openings of the new coil.
Step 2: Saturate the Cotton
Allow the cotton to absorb the e-liquid evenly. Avoid adding too much, as over-saturating the coil can cause flooding.
Step 3: Install the Coil
Insert the primed coil into the tank or pod according to the manufacturer's instructions.
Step 4: Fill the Tank
Fill the tank with a compatible e-liquid, ensuring the liquid level reaches the recommended fill line.
Step 5: Let the Coil Soak
Leave the filled tank standing for 5-10 minutes. This gives the wick enough time to become fully saturated.
Step 6: Take a Few Gentle Puffs
Take a few gentle draws without firing the device. This can help pull e-liquid into the wick.
Step 7: Start at a Lower Wattage
Begin vaping below the coil recommended wattage range. Lower power helps the coil break in gradually.
Step 8: Increase Power Gradually
Raise the wattage in small increments until you reach your preferred balance of flavour, vapour production, and warmth.
Properly priming a sub-ohm coil can improve performance from the first puff and help prevent premature coil damage.
How Long Do Sub-Ohm Coils Last?
A sub-ohm coil typically lasts between 1 and 3 weeks, depending on wattage, e-liquid sweetness, vaping frequency, and coil priming. Lower wattage operation and proper coil priming often help extend coil life, while excessive wattage can shorten it.
E-liquid sweetness is another important factor. Sweetened e-liquids can leave residue on the coil more quickly, leading to reduced flavour and vapour production. Signs that a coil may need replacing include a burnt taste, weaker flavour, darker e-liquid, gurgling, or a noticeable drop in vapour output.
Sub-Ohm vs Nic Salt Vaping
Sub-ohm vaping and nic salt vaping are designed for different vaping styles and nicotine strengths. Sub-ohm devices frequently use freebase nicotine and lower nicotine levels, while nic salt devices are commonly paired with higher-strength nicotine and MTL vaping.
| Feature | Sub-Ohm Vaping | Nic Salt Vaping |
|---|---|---|
| Nicotine Type | Freebase Nicotine | Nicotine Salt |
| Nicotine Strength | 3mg-6mg | Up to 20mg/ml |
| Vaping Style | DTL (Direct-to-Lung) | MTL (Mouth-to-Lung) |
| Coil Resistance | Below 1.0Ω | 0.6Ω-1.8Ω |
| Vapour Production | High | Moderate |
Sub-ohm setups are popular for flavour and cloud production, while nic salt devices focus on higher nicotine delivery in a more compact format.
Can You Use Nic Salts in a Sub-Ohm Tank?
High-strength nicotine salts are not recommended for use in a sub-ohm tank. Most sub-ohm devices operate at higher wattages and produce larger amounts of vapour, which can result in excessive nicotine intake when paired with higher-strength nic salts, particularly 20mg formulations.
This may lead to an uncomfortable vaping experience, including dizziness, nausea, and a harsh throat hit. Sub-ohm tanks are typically suited to lower-strength e-liquids, such as 3mg or 6mg freebase nicotine. While some low-strength nic salts can be used in certain setups, high-strength nicotine salts are better suited to MTL devices rather than DTL sub-ohm vaping.

Frequently Asked Questions
Unlike standard vape tanks, a sub-ohm tank is built for low-resistance coils, higher airflow, and increased vapour production. These tanks feature increased airflow and are intended for DTL (Direct-to-Lung) vaping with high-VG e-liquids.
Sub-ohm coils can wear out more quickly when used at excessive wattages, with very sweet e-liquids, or without proper priming. Chain vaping and allowing the wick to dry out may also shorten coil lifespan.
Most sub-ohm users prefer nicotine strengths of 3mg or 6mg. Since sub-ohm devices produce more vapour, lower nicotine levels are recommended than those used in MTL devices.
A sub-ohm coil is any vape coil with a resistance below 1.0 ohm. Common resistance ranges include 0.15 ohm, 0.2 ohm, 0.3 ohm, and 0.4 ohm.
High-VG e-liquids, typically with a 70/30 or 80/20 VG/PG ratio, are considered the best match for sub-ohm coils and mesh coil systems.
Many vapers prefer mesh coils because they heat e-liquid more evenly and often deliver a smoother, more consistent flavour throughout the coil lifespan.
Sub-ohm kits perform best with high-VG e-liquids. While some devices may handle 50/50 e-liquids, thinner liquids can increase the risk of flooding or leaking in tanks paired with high-VG vape juice.
For average use, sub-ohm coils last between one and three weeks. Heavy use, sweet e-liquids, and higher wattage settings may require more frequent replacement.
High-strength nic salts are not recommended for sub-ohm tanks. Sub-ohm kits are usually paired with lower nicotine strengths, while high-strength nic salts are better suited to MTL vaping.
Sub-ohm vaping is not necessarily better than regular vaping, but it provides greater vapour production, stronger flavour, and increased airflow. Many users prefer sub-ohm devices for DTL vaping, while others choose MTL devices for a tighter draw and higher nicotine strengths.
Sub-ohm vape kits are designed with multiple safety features, including short-circuit protection, overcharge protection, and low-voltage protection. Safe use depends on following the manufacturer's instructions, using compatible batteries, and operating the device within the recommended wattage range.
The best wattage depends on the coil being used. Most sub-ohm coils perform within a recommended range printed on the coil itself. Many users vape between 40W and 80W for a balance of flavour, vapour production, and battery life.
