Electronic Cigarette Ohms Guide: A Beginner’s Guide
Are you new to vaping and wondering, “What do ohms mean in electronic cigarettes?” Understanding ohms is essential for customiSing your vaping experience, whether you’re using a sub-ohm tank or a standard vape device. In this beginner-friendly guide, we’ll explain what electronic cigarette ohms are, how they affect vapour production, flavour, and throat hit, and help you choose the right coil resistance for your needs.
What are electronic cigarette ohms?
Ohms (Ω) measure the electrical resistance of the coil inside your vape device. The resistance level determines how much current flows through the coil when you vape, directly impacting vapour production, flavour intensity, and the throat hit you experience. Lower ohm coils (sub-ohm, below 1.0Ω) allow more current to pass through, producing larger vapour clouds and a smoother throat hit. Higher ohm coils (above 1.0Ω) restrict current, resulting in less vapour but a more intense flavour and stronger throat hit—ideal for mouth-to-lung vaping.
Why Understanding Ohms Matters
- Vapour Production: Sub-ohm coils (<1.0Ω) generate more vapour, perfect for direct-to-lung (DTL) vaping and cloud chasing. Higher resistance coils produce less vapour, suiting those who prefer discreet, cigarette-like draws.
- Flavour Experience: Higher resistance coils often deliver more nuanced flavours due to gentler vaporisation, while sub-ohm coils can sometimes mute delicate notes.
- Throat Hit: If you want a stronger, cigarette-style throat hit, opt for higher ohm coils. For a smoother inhale, sub-ohm coils are the way to go.
- Battery Life & E-Liquid Consumption: Lower resistance coils consume more power and e-liquid, while higher resistance coils are more economical.
The relationship between ohms and vaping experience
The ohm level of your vaping device has a direct impact on your overall vaping experience. By understanding the relationship between ohms and other vaping parameters, you can fine-tune your device to achieve your desired results.
Vapour Production: Lower resistance coils (sub-ohm) allow for higher wattage and current flow, resulting in increased vapour production. This is often preferred by cloud chasers who enjoy dense, voluminous clouds. Conversely, higher resistance coils (above 1 ohm) typically produce less vapour but may provide a more focused and flavourful vaping experience.
Flavour: The resistance of the coil can also affect the flavour of your e-liquid. Higher resistance coils tend to provide a more pronounced and nuanced flavour profile, as the lower wattage allows the e-liquid to vaporise more gently and preserves the delicate flavour notes. Sub-ohm coils, on the other hand, can sometimes produce a slightly muted flavour due to the higher wattage and faster vaporisation.
Throat Hit: The resistance of the coil also plays a role in the throat hit, or the sensation you feel when inhaling the vapour. Higher resistance coils generally provide a more pronounced and satisfying throat hit, which is often preferred by those who enjoy a harsher, more cigarette-like experience. Sub-ohm coils, with their lower resistance and higher wattage, tend to produce a smoother, less intense throat hit.
Types of Vape Coils by Ohm Level
| Coil Type | Resistance (Ohms) | Best For | Vapour Production | Flavour | Throat Hit |
|---|---|---|---|---|---|
| Standard Resistance | 1.0Ω and above | Mouth-to-lung vaping | Low | High | Strong |
| Sub-Ohm | Below 1.0Ω | Direct-to-lung, clouds | High | Medium | Smooth |
| Micro-Coil | Below 0.5Ω | Advanced, max clouds | Very High | Medium | Smooth |
Different types of ohms for electronic cigarettes
In the world of electronic cigarettes, there are several different types of ohms that vapers can choose from, each with its own unique characteristics and benefits. Understanding these different ohm levels can help you make an informed decision when selecting the right coil for your vaping needs.
Standard Resistance Coils (1.0 ohm and above): These coils have a resistance of 1.0 ohm or higher and are commonly used in traditional, mouth-to-lung (MTL) style vaping devices. They typically operate at lower wattages, producing a tighter, more cigarette-like draw and a stronger throat hit. Standard resistance coils are often preferred by those who are transitioning from traditional cigarettes or seeking a more discreet vaping experience.
Sub-Ohm Coils (below 1.0 ohm): Sub-ohm coils have a resistance of less than 1.0 ohm, allowing for higher wattage and increased vapour production. These coils are commonly used in direct-to-lung (DTL) style vaping devices and are favored by cloud chasers and those who enjoy a more intense, voluminous vaping experience. Sub-ohm coils typically produce larger, denser clouds and a smoother throat hit compared to standard resistance coils.
Micro-Coils (below 0.5 ohm): At the lower end of the spectrum, micro-coils have a resistance of less than 0.5 ohm. These ultra-low resistance coils are designed for high-powered devices and are often used by advanced vapers who are seeking the ultimate in vapour production and flavour. Micro-coils require careful attention to battery safety and power management, as they can draw a significant amount of current from the device’s battery.
Choosing the right ohm for your vaping needs
When it comes to choosing the right ohm level for your vaping device, there is no one-size-fits-all solution. The optimal ohm level will depend on your personal preferences, the type of device you’re using, and the e-liquid you’re vaping.
MTL
Mouth-to-Lung (MTL) Vaping: If you’re using a more traditional, MTL style device, such as a compact pod system or a simple vape pen, you’ll generally want to opt for a higher resistance coil, typically in the range of 1.0 ohm to 1.5 ohm. These higher resistance coils will provide a tighter, more cigarette-like draw and a stronger throat hit, which is often preferred by those transitioning from traditional cigarettes.
RDL
Restricted Direct-to-Lung (RDL) Vaping: RDL vaping occupies the middle ground between MTL (Mouth-to-Lung) and DTL (Direct-to-Lung) styles. With RDL, you inhale the vapour directly into your lungs, but with a more restricted airflow than classic DTL vaping. This creates a draw that is airier than MTL but tighter than DTL, resulting in a satisfying throat hit, enhanced flavour, and moderate cloud production.
RDL vaping typically uses coils with resistances between 0.5 and 0.8 ohm, allowing for a balance of flavour and vapour without the intensity of full DTL setups. Many modern devices offer adjustable airflow and are compatible with both MTL and RDL coils, giving you flexibility to tailor your experience. You can use a variety of e-liquids, including high-PG options for a stronger throat hit or 50/50 blends for a smoother vape.
This hybrid style is ideal for vapers who want more vapour and a looser draw than MTL, but aren’t ready for the open airflow and higher power of DTL devices. RDL is especially popular among those seeking a versatile, flavourful, and moderately cloudy vape without sacrificing nicotine satisfaction
DTL
Direct-to-Lung (DTL) Vaping: For those who enjoy a more intense, cloud-chasing vaping experience, a sub-ohm coil (below 1.0 ohm) is the way to go. These lower resistance coils allow for higher wattage and increased airflow, resulting in larger, denser vapour clouds and a smoother throat hit. Sub-ohm vaping is often preferred by experienced vapers who are looking to maximize their flavour and vapour production.
Wattage Considerations: When choosing the right ohm level, it’s also important to consider the wattage capabilities of your device. Higher resistance coils (above 1.0 ohm) typically operate at lower wattages, while sub-ohm coils require higher wattages to achieve optimal performance. Make sure your device can handle the wattage required for the coil resistance you choose.
E-Liquid Viscosity: The viscosity of your e-liquid can also play a role in the optimal ohm level. Higher VG (Vegetable Glycerin) e-liquids, which are thicker and produce more vapour, may perform better with lower resistance coils. Conversely, higher PG (Propylene Glycol) e-liquids, which are thinner and provide a stronger throat hit, may work better with higher resistance coils.
By considering these factors, you can make an informed decision and choose the right ohm level for your vaping needs, ensuring a consistently enjoyable and satisfying vaping experience.
