With the right sub-ohm vape kit, you can fine-tune your settings to achieve the perfect balance of flavour and DTL vapour production. So whether you’re chasing big clouds or rich flavours, sub-ohm vaping delivers a satisfying and rewarding experience. We’re here to break down exactly how to choose the best one for you and show you our top 5 sub ohm vape kits of 2025.

But First, What is DTL and Sub-Ohm Vaping?

Direct-to-lung (DTL) vaping has surged in popularity over the last few years. Unlike mouth-to-lung (MTL) vaping – which mimics the sensation of smoking a cigarette – DTL vaping allows users to inhale vapour directly into their lungs, creating a smoother and more intense experience. DTL vaping involves inhaling vapour directly into the lungs, bypassing the mouth. Sub-ohm vaping uses coils with a resistance rating below 1.0 ohms, allowing for larger clouds and more robust flavours. These kits typically offer high power output, adjustable airflow, and temperature control, providing a highly customisable vaping experience.

Benefits of DTL and Sub Ohm Vaping:

• Bigger clouds: Sub-ohm kits are designed for high-wattage vaping, making them ideal for all the cloud chasers out there.
• Better flavour: Vape juice with a high-VG ratio should always be used in sub-ohm devices to enhance flavour. (It’s advisable to avoid nic salt e-liquids, these may be too strong for this sort of hard)
• Customisation: Most sub-ohm kits offer adjustable airflow, temperature control, and multiple coil options.
• Stronger nicotine hit: While sub-ohm vaping uses lower nicotine levels, the increased vapour production delivers a satisfying throat hit.

Here’s How To Choose the Right DTL Vape Kit

Selecting the right DTL vape kit can be a daunting task so here’s some key things to consider to ensure you make the best choice:

• Power output: Look for a vape kit with a high power output, if you’re eager to produce large clouds and intense flavours. Typically the most powerful kits will range between 50W and 200W.
• Coil compatibility: Ensure the vape kit is compatible with sub-ohm coils, preferably with a resistance rating below 1.0 ohms. This is crucial for achieving the desired vapour production and flavour intensity.
• Adjustable airflow: A vape kit with adjustable airflow allows you to customise your vaping experience. You can control the amount of air that mixes with the vapour, enhancing both flavour and cloud production.
• Temperature control: Temperature control is a valuable feature that lets you adjust the coil’s temperature to optimise vapour production. This prevents dry hits and extends the lifespan of your coils.
• Battery life: Consider a vape kit with a long-lasting battery, preferably with a capacity of 2000mAh or higher. This ensures you can enjoy extended vaping sessions without frequent recharges.

By keeping these factors in mind, you can find a DTL vape kit that meets your needs and provides a satisfying vaping experience.

Safety & Sub Ohm Kit Maintenance

Maintaining your sub-ohm vape kit is essential for a safe and satisfying vaping experience. Here are some safety tips to keep in mind:

• Use a battery safety case: Protect your batteries from damage by using a battery safety case. This helps prevent accidents and extends the life of your batteries.
• Follow proper charging procedures: Always follow proper charging procedures to prevent overcharging and damage to your batteries. Use the charger that comes with your vape kit and avoid leaving it unattended while charging.

By following these safety tips and maintaining your vape kit regularly, you can enjoy a safe and satisfying sub-ohm vaping experience.

Which E-Liquid Should I Use for Sub-Ohm Vaping?

Choosing the right e-liquid is crucial for a satisfying sub-ohm vaping experience. Here are some tips to help you make the best choice:

• High VG e-liquid: Sub-ohm coils require high VG (vegetable glycerin) e-liquid to function effectively. Look for e-liquids with a VG ratio of 70% or higher to ensure smooth vapour production and rich flavours.
• Low nicotine e-liquid: Sub-ohm vaping often requires lower nicotine levels, as the higher power output can intensify the nicotine hit. Opt for e-liquids with nicotine levels between 3mg and 6mg to avoid harsh throat hits.
• Flavourful e-liquid: Sub-ohm vaping is all about flavour, so choose e-liquids with rich and intense flavour profiles. This enhances the overall vaping experience and makes each puff enjoyable.
