Sub Ohm Vape Kits

Sub-ohm vape kits are built for direct-to-lung (DTL) vaping. With lower-resistance coils and more airflow, they let you create bigger clouds. Our sub-ohm vape kits include box mod kits with adjustable wattage along with simpler pod-style DTL kits. We carry the big-name brands like Aspire, Geekvape, Voopoo, Innokin, and Vaporesso. Each kit has everything you need to start besides e-liquid (and external batteries for some mods). Sub-ohm kits work best with high-VG e-liquids at low-level nic strengths, like 3mg or 6mg shortfills. If you prefer a tighter, cigarette-style draw, an MTL kit will suit you better.

What Is a Sub-Ohm Kit and How Does It Differ From Regular Vape Kits?

A sub-ohm kit is a high-performance vaping device designed for direct-to-lung (DTL) vaping, using coils with resistance lower than 1.0 ohm. These kits produce significantly more vapour and deliver enhanced flavour compared to other vapes. They're ideal for users who enjoy a more intense vaping experience, bigger clouds, and richer flavour profiles. However, they require more power and use e-liquids with higher VG content and lower nicotine strengths (typically 3-6mg) compared to regular kits.

What Types of Sub-Ohm Kits Are Available?

There are two main types of sub-ohm kits available:

  • Box Mod Kits: Traditional setup with a powerful battery unit and a separate tank. These offer the most customisation options and typically have extensive features like wattage control and temperature control.
  • Sub-ohm Pod Kits: More compact and user-friendly devices that combine sub-ohm capabilities with the convenience of a pod system. Perfect for those wanting powerful performance in a more portable format.

How Do Sub-Ohm Vapes Work?

A sub-ohm kit consists of a vape mod that is powered by either 18650 or 21700 batteries and has a refillable sub-ohm tank that's designed to work with higher wattage and temperatures. And as mentioned earlier, sub-ohm vapes use coils that have a sub-ohm, or less than 1-ohm resistance. 

When you activate the device (by pressing the power button or through inhale activation), electricity flows through the coil, which heats up and vaporizes the e-liquid. 

Which Nicotine Strength Should I Use With a Sub-Ohm Kit?

Due to the increased vapour production of sub-ohm devices, you should use lower nicotine strengths to prevent harsh throat hits and nicotine overdose. Recommended nicotine strengths for sub-ohm vaping:

  • 3mg: Ideal for most sub-ohm vapers
  • 6mg: Maximum recommended strength for sub-ohm vaping
  • 0mg: Suitable for those who enjoy the flavour and clouds without nicotine

Never use high-strength nicotine salts (20mg) or regular 10ml e-liquids above 6mg in sub-ohm devices.

Do Sub-Ohm Coils Burn Faster?

Sub-ohm coils can often burn faster. This isn’t a universal case, but high-VG vape juices contain more sugar than 50/50 and high-PG e-liquids. This increased degree of sweeteners can negatively impact the wicking cottons in your sub-ohm coils. For more tips on the different kinds of vaping, check out our guide on DTL vs MTL vaping to find out which is best for you. 

What Type of E-liquid Should I Use With a Sub-Ohm Kit?

Sub-ohm kits work best with high VG e-liquids. Here's a guide:

  • 70/30 VG/PG: Ideal ratio for most sub-ohm devices
  • 80/20 VG/PG: Suitable for cloud chasing
  • 60/40 VG/PG: Minimum VG recommendation for sub-ohm vaping

High VG liquids produce thicker vapour and smoother throat hits, perfect for the direct-to-lung vaping style associated with sub-ohm devices.

Can I Use Nic Salt in Sub-Ohm?

You can only comfortably use nic salts in a sub-ohm kit if that kit also has MTL coils. Sub-ohm vape kits and compatible coils will fire at high power outputs, generating a frankly uncomfortable level of high-nicotine nic salt vapour. Instead, we suggest you look into DTL e-liquids with the help of our high VG juice guide.

Is Sub-ohm Vaping Better? 

If you’re someone who loves vaping massive clouds and wants to enjoy a smoother, richer flavour, then sub-ohm vaping may be just the thing for you! Here are the advantages of sub-ohm vapes: 

  • Massive Cloud Production: The high-powered sub-ohm vape devices and high VG liquids is a dream for cloud-chasers - allowing tonnes of thick clouds. 
  • Smoother, Intense Flavour: The high-VG e-liquids used in sub-ohm kits unlock a much smoother, more intense, and delicious flavor experience for vapers. 
  • Customizability: Since many sub-ohm kits offer features such as adjustable airflow, wattage and voltage, it gives the user a great degree of control over their vaping experience. 
  • More Satisfying Lung Hit: Sub-ohm vaping is great for vapers looking for a satisfying, deep-lung hit that takes the vapor straight into your lungs.

Does Sub Ohm Hit Harder?

Interestingly, no, sub-ohm vaping doesn’t hit harder. This is because sub-ohm vapes use high-VG vape juices, which are a lot smoother on the throat, even when inhaled in vast quantities. It’s a common misconception that can lead to an ill-informed purchase, and to avoid such mistakes, we suggest reading our sub-ohm vape kit guide.

Does Lower Ohms Use More Liquid?

Yes, lower ohms use more vape liquid due to the higher wattage outputs and the ways that sub-ohm vape coils atomise vape juice rapidly. 10ml bottles will run out very quickly with a sub-ohm device, so we suggest reading up on our shortfills guide to find out how to acquire a large bottle of e-liquid.

Is a Sub-Ohm Kit Suitable for Beginners?

While sub-ohm kits are more powerful than standard devices, many modern sub-ohm kits (especially pod-style ones) are quite user-friendly. However, beginners should consider:

  • These devices require more attention to battery safety
  • You'll need to understand basic power settings and coil resistance
  • E-liquid consumption is higher than regular kits
  • Initial cost may be higher due to advanced features

If you're new to vaping but want a sub-ohm device, consider starting with a sub-ohm pod kit, which offers a good balance of performance and ease of use.

What Should I Consider When Choosing Between Different Sub-Ohm Kits?

Key factors to consider when selecting a sub-ohm kit:

  • Battery Life: Higher wattage means more power consumption
  • Portability: Box mods are larger but more powerful; pod systems are more compact
  • Ease of Use: Consider your comfort with technical features and maintenance
  • Tank Capacity: All tanks comply with 2ml TPD regulations, but some have bubble glass options
  • Coil Compatibility: Check the availability and variety of compatible vape coils
  • Features: Consider if you need advanced features like temperature control or variable wattage

Frequently Asked Questions

What is a sub-ohm (DTL) vape kit?

A sub-ohm kit uses coils with a resistance below 1 ohm, paired with a battery that can deliver more power. You inhale the vapour straight into your lungs, which is why it’s called direct-to-lung (DTL) vaping. With high-VG e-liquid, it gives larger clouds, a fuller flavour and a smoother draw than a standard mouth-to-lung (MTL) kit.

Who are sub-ohm kits best for?

Sub-ohm kits suit vapers who enjoy big clouds, strong flavour and a loose, airy draw, and who use lower-nicotine e-liquid. If you want a tight, cigarette-like draw or use higher-strength nic salts, an MTL pod kit is usually a better fit.

What e-liquid should I use in a sub-ohm kit?

Use a high-VG e-liquid, typically 70VG/30PG or higher, at either 0mg or a low nicotine strength such as 3mg or 6mg. Thicker high-VG liquid suits low-resistance coils and produces more vapour. Do not use nic salts and high-PG liquids in a sub-ohm kit, as they will feel harsh and are likely to leak.

What's the difference between MTL and DTL vaping?

MTL (mouth-to-lung) works like drawing on a cigarette. You first pull vapour into your mouth, and then inhale it into your lungs. MTL kits use higher-resistance coils and tighter airflow to create a more restricted draw. On the other hand, DTL (direct-to-lung) involves inhaling vapour straight into your lungs, without holding it in your mouth first. DTL kits have more open airflow and use lower-resistance coils to produce larger amounts of vapour.

How often should I change the coil?

Most vapers change a sub-ohm coil every one to two weeks. However, it depends on your vaping habits, wattage, and even the e-liquid flavour type. Sweet liquids, for example, can wear coils out faster. A good rule of thumb to follow is to change the coil when flavour fades or you notice a burnt taste. Replacement coils for each kit are in our vape coils range.
