Sub-ohm coils have revolutionised the vaping experience, offering enthusiasts a way to achieve more intense best vape juice flavours and bigger clouds. These vape coils, characterised by their resistance being less than one ohm, have become a cornerstone in the vaping community. This blog delves into what makes sub-ohm vape coils special, how they work, and the benefits and considerations for vapers.
What are Sub-Ohm Coils?
Sub-ohm coils, as the name suggests, have a resistance of less than one ohm. In electrical terms, resistance is a measure of how much a coil opposes the flow of electricity. Lower resistance allows more current to pass through, generating more heat and, consequently, more vapour. This increased vapour production translates to a richer flavoured vape juice and larger clouds, which is the hallmark of the sub-ohm vaping experience.
The Science Behind Sub-Ohm Coils
The principle behind sub-ohm vaping lies in Ohm's Law, which states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). In simpler terms, lowering the resistance increases the current, provided the voltage remains constant.
When a sub-ohm coil is used in a vaping device, the battery delivers more current to the coil. The increased current causes the coil to heat up faster and to a higher temperature, vaporising the e-liquid more efficiently. This rapid and enhanced vaporisation is what produces the dense clouds and robust flavours that sub-ohm vapers crave.
Benefits of Sub-Ohm Coils
- Enhanced Flavour: Sub-ohm coils vaporise e-liquid at higher temperatures, which can enhance the complexity and intensity of flavours. This is particularly appealing for vapers who prioritise taste.
- Increased Vapour Production: For those who enjoy creating large clouds, sub-ohm coils are ideal. The high vapour production is perfect for tricks and for those who prefer a more visually impressive vaping experience also known as dtl vaping.
- Warmer Vapour: Some vapers prefer the sensation of warmer vapour, which sub-ohm coils naturally provide due to their higher heat output.
- Throat Hit: The increased vapour production can also deliver a more satisfying throat hit, which many ex-smokers find appealing.
Considerations and Safety
While sub-ohm vaping has its benefits, it also comes with certain considerations and safety precautions.
- Battery Safety: Sub-ohm vaping demands more from your vape batteries. It's essential to use high-quality, high-drain batteries that can handle the increased current. Using inappropriate batteries can lead to overheating and even explosions.
- E-Liquid Consumption: Due to the higher vapour production, sub-ohm vaping consumes more e-liquid. This means you’ll go through your e-liquid faster, which can be costly.
- Nicotine Levels: Sub-ohm vaping delivers nicotine more efficiently. Therefore, it’s advisable to use lower nicotine vape concentrations to avoid excessive intake, which can lead to nicotine sickness.
- Device Compatibility: Not all vape kits are designed for sub-ohm coils. Ensure your device is capable of handling sub-ohm coils and that it has appropriate airflow and wattage settings ideally look for advanced vape kits.
