A Beginner's Guide to Sub-Ohm Devices: Choosing the Right E-Liquid for an Optimal Vaping Experience

Sub-ohm vaping has become a popular choice among vapers who prefer dense clouds and rich flavors. These devices are designed for those who want an enhanced vaping experience, but using the right e-liquids is crucial to get the most out of your sub-ohm device. This guide will walk you through the best practices for using sub-ohm devices, particularly focusing on the type of e-liquids that provide the best experience.
Important Note for Sub-Ohm Vaping
Sub-ohm devices are not recommended for use with:
- Nicotine salt e-liquids: 20mg (2%), 30mg (3%), or 50mg (5%).
- 50VG/50PG freebase nicotine e-liquids.
If you’re new to sub-ohm vaping, here’s everything you need to know about why these types of e-liquids are not suitable and how to choose the right e-liquid for a satisfying vape.
For an optimal sub-ohm vaping experience, stick to high VG e-liquids with low nicotine concentrations.

Why You Should Avoid Nicotine Salts and 50VG/50PG E-Liquids in Sub-Ohm Devices
Sub-ohm devices are designed primarily for direct lung (DL) vaping and work best with:
- Lower nicotine levels (below 12mg).
- High VG e-liquids (70VG/30PG or higher).

Using nicotine salts or 50VG/50PG freebase nicotine in sub-ohm devices can lead to an uncomfortable and harsh vaping experience due to the device’s higher power output and the characteristics of sub-ohm coils. Here’s a breakdown of why these types of e-liquids are not recommended:
1. Leaking
Sub-ohm devices are designed for high VG e-liquids, which are thicker. Using thinner liquids like nicotine salts or 50VG/50PG freebase can lead to leakage through the coil and airflow openings, resulting in a messy experience and possible damage to your device.
2. Dry Hits
Coils in sub-ohm devices are optimized for thicker, high VG e-liquids. Using thinner e-liquids can result in the coil not adequately absorbing the liquid, leading to unpleasant dry hits and a burnt taste.
3. Compromised Flavor
Sub-ohm coils are engineered to enhance the rich, robust flavors of high VG e-liquids. Using nicotine salts or 50VG/50PG e-liquids can dilute the flavor, affecting the overall quality of your vaping experience.
4. Low Vapor Production
One of the key features of sub-ohm devices is their ability to produce large vapor clouds. nicotine salts or 50VG/50PG e-liquids, particularly at lower wattages, can significantly reduce vapor production, defeating the purpose of using a sub-ohm device.
5. Safety Concerns
Nicotine salts are meant for low-power, mouth-to-lung (MTL) devices. Using these in a sub-ohm device can lead to excessive nicotine intake, potentially causing side effects like dizziness, nausea, or headaches.
6. Inadequate Coil Performance
Sub-ohm coils are built for higher wattage use (typically above 25W). Running these coils at lower wattages, as required for nicotine salts, leads to poor performance, potentially shortening the coil’s lifespan.
7. Battery Drain
Sub-ohm devices are designed for consistent power output. Using e-liquids that require lower wattage settings can cause inconsistent power consumption, leading to faster battery drain and the need for more frequent recharging.
8. Inefficient Nicotine Delivery
Nicotine salts are formulated for quick absorption and a smooth throat hit. Using them in a sub-ohm device results in too much nicotine being delivered too quickly, which can lead to an overwhelming experience.

Best Practice: Use High VG E-Liquids
For an optimal sub-ohm vaping experience, we recommend using e-liquids with:
- High VG content (70VG/30PG).
- Nicotine concentrations between 0mg and 12mg.
This setup ensures a smoother, more enjoyable vape, without the risks mentioned above.
What to Do for a Better Vaping Experience
If you prefer to use nicotine salts, we recommend switching to a mouth-to-lung (MTL) device for a better experience. Here are some recommended devices:






Tips to Avoid Issues if You Choose to Use Nicotine Salts with a Sub-Ohm Device
- Use a Higher-Resistance Coil: Opt for coils designed for MTL vaping, such as 1.0 ohm or higher.
- Keep the Wattage Low: Stay under 15 watts to avoid an excessively strong nicotine hit and ensure a smoother experience.
Safety Warning: Be cautious when using 50mg salt nicotine with sub-ohm devices, even at low wattages, to prevent dizziness, nausea, or discomfort.
FAQ’s
Conclusion
For the best vaping experience with sub-ohm devices, stick to high VG e-liquids (70VG/30PG) with low nicotine concentrations (0mg to 12mg). Understanding the compatibility of your device with different types of e-liquids will help you avoid potential issues like leaking, dry hits, and overwhelming nicotine delivery.
