Coils

 Choosing the right e-liquid for your coil type is essential. Here’s a guide to selecting the ideal VG/PG ratio and nicotine strength based on your coil resistance:

Low-Resistance Coils (Below 1 Ohm):

• Best suited e-liquid – High-VG e-liquids (70% VG or higher) work best. Low-resistance coils work well with these liquids because VG is thicker and produces denser vapour clouds. These e-liquids also create a smoother throat hit, which balances the intensity of DTL vaping.
• Nicotine strength – Low-nicotine strength (between 3-6 mg) is recommended. Higher levels can be too intense with sub-ohm coils.

High-Resistance Coils (above 1 Ohm):

• Best suited e-liquid: High-PG or 50/50 VG/PG e-liquids are ideal for high-resistance coils. PG is thinner, allowing it to wick faster, especially with MTL setups. It also provides a stronger throat hit, complementing the MTL vaping style. Higher ohm coils are particularly compatible with high-PG e-liquids, enhancing the mouth-to-lung experience.

Nicotine strength: Higher nicotine levels (10-20 mg with freebase or 20mg for nicotine salts) work best, as the lower vapour production and tighter draw make these strengths manageable and satisfying.

Low-resistance coils are best suited for vapers who vape with high VG e-liquids, and want to see huge clouds and intense flavours. 

• Direct-to-lung (DTL) vapers: Low-resistance coils allow for a direct-to-lung (DTL) inhale, where the vapour is drawn directly into the lungs rather than held in the mouth first. This style is popular among experienced users who enjoy a more intense, robust inhale and want to maximise vapour output and flavour. These coils offer advanced vapers a fully customizable setup so they can really find the perfect inhale for them!
• High-VG e-liquids users: VG (Vegetable Glycerin) is a thicker liquid that requires more power to vaporise effectively. Sub-ohm coils work exceptionally well with high-VG e-liquids because they produce larger & denser clouds.

Higher power vape kits: Sub-ohm coils work best at higher power settings (wattages typically range from 30W to 200W) so they produce warmer vapour that with an intense taste.

High-resistance coils are for vapers who want to be discreet and have the option of high nicotine strengths. 

• Beginners & discreet vapers: High-resistance coils are especially popular among new vapers who may find the intense experience of sub-ohm vaping a little too much for them. They’re also an excellent choice for those who prefer a more subtle, less noticeable vape, as high-resistance coils produce smaller vapour clouds. In addition, they tend to conserve battery and e-liquid, making them a more economical choice.
• 50/50 VG/PG or high-PG e-liquids users: Higher-resistance coils are compatible with thinner e-liquids, such as those with a 50/50 VG/PG blend or higher PG (Propylene Glycol) content. PG is less viscous than VG, and it provides a strong throat hit, making high-resistance coils perfect for e-liquids with a higher PG ratio. These thinner liquids also wick more easily with higher-resistance coils, reducing the risk of dry hits.
• Mouth-to-Lung (MTL) vapers: MTL vaping closely mimics the sensation of smoking a traditional cigarette. This style is popular among ex-smokers and beginners because it offers a satisfying, familiar inhale and typically produces a discreet amount of vapour.

Lower power vape kits: High-resistance coils work best at lower power settings, usually between 7W to 20W. These lower wattages result in cooler vapour, which is less intense than sub-ohm vapour and ideal for a smooth, mild vape. The cooler vapour and restricted airflow make these coils ideal for those who want a similar experience to traditional cigarette smoking.

 The lifespan of a vape coil depends on several factors, including your frequency of use, the type of e-liquid you’re using, your vaping habits, and the specific coil resistance. 

Coils generally last one to two weeks, though heavy vapers or those using certain e-liquids may need to replace them more frequently.

 Unlike traditional coils made from a single round wire, mesh coils use a thin strip of metal with a mesh-like structure. This design increases the surface area that comes into contact with the e-liquid, allowing for more efficient heating and vapour production. The main difference between mesh and traditional coils is in their structure. Traditional coils use a spiral of wire, while mesh coils have a woven, net-like design. This structure allows mesh coils to heat up more evenly for a fuller, richer flavour.

There are a few ways to tell when to change your coil, these are: 

1. Reduced flavour: A drop in flavour intensity is one of the first signs that your coil is wearing out. When a coil is fresh, it delivers a strong, vibrant flavour. Over time, residue builds up on the coil and wick, muting the flavour of your e-liquid. If your favourite e-liquid starts tasting bland, it’s likely time for a new coil.
2. Burnt taste: One of the most noticeable signs of a worn-out coil is a burnt or “charred” taste. This burnt taste often occurs when the wick inside the coil becomes singed due to dry hits from prolonged use. A burnt taste is usually a sign that the wick can no longer absorb e-liquid effectively, indicating the coil needs to be replaced.
3. Reduced vapour production: When your coil is past its prime, you may notice less vapour with each inhale. If you’re accustomed to a certain level of vapour output and suddenly notice a reduction, it is likely because the coil can’t heat the e-liquid efficiently.

Gurgling sounds or leaks: If your coil isn’t properly saturated, it may produce gurgling sounds or might leak! This occurs when the coil’s wick can’t hold e-liquid effectively anymore because the structure is deteriorating. It’s true that leaks can be caused by other factors (the seal may not be flush against the mod or tank, for example) but persistent gurgling can indicate a coil needs replacing!

 MTL (Mouth-to-Lung) vaping – With MTL, you inhale vapour into your mouth before drawing it into your lungs. This style is recommended for higher-resistance coils and is suitable for beginners or those seeking a similar sensation to smoking traditional cigarettes.

DTL (Direct-to-Lung) vaping – DTL vaping involves inhaling vapour directly into the lungs. This style produces more vapour and offers a more intense flavour experience. DTL is ideal for low-resistance coils and works best with high-powered devices and high-VG e-liquids.

 Nicotine salts are specifically designed for high-resistance coils above 1 ohm! These coils deliver a smoother, stronger throat hit at lower wattages. The higher resistance provides a moderate vapour production that complements the high nicotine strength of nic salts, making this a perfect range for smooth inhales without no overwhelming harshness!

Using nicotine salts with low-resistance coils is not recommended. Sub-ohm coils produce more intense vapour and higher temperatures – and when paired with nic salts - this low resistance can lead to a harsh throat hit and an overpowering nicotine experience! Instead, stick to mouth-to-lung (MTL) devices and high-resistance coils for an ideal nic salt experience.

 A burnt hit is an inhale of burnt wicking material – it’ll taste horrid and smokey! To avoid burnt hits, follow these essential tips to ensure a smooth, uninterrupted vape:

1. Prime your coil properly. Always prime a new coil by thoroughly saturating the wicking material (cotton or wood pulp) with e-liquid before use. Place a few drops of e-liquid directly on the coil’s wick and allow it to soak in. This will help the coil avoid dry spots that could burn when you take your first hit!
2. Allow the e-liquid to soak! After filling your tank or pod, always let it sit for at least 5-10 minutes before taking your first hit. This waiting period ensures the wick is fully soaked and reduces the risk of burning. Failing to do so will result in a burnt hit!
3. Avoid high wattages on low-resistance coils. If your coil isn’t rated for high wattages, using a high power setting can lead to burnt hits as the coil overheats. Check the recommended wattage range for your coil and stay within those limits to avoid overheating.
4. Check e-liquid levels. Running your tank too low on e-liquid can expose the coil to air instead of liquid, leading to dry or burnt hits. Refill your tank before it gets too low to keep the wick soaked!

Use the right e-liquid in your vape coil. Some e-liquids (high-VG) are too thick for certain coils, leading to slow wicking and potential burning. Make sure the e-liquid matches the coil’s recommended VG/PG ratio.

 Most vape brands design coils are designed specifically to fit their devices, making it essential to use the correct coil for your particular vape. Here’s how to find the right fit for your vape kit/vape mod:

Check your device manual. The manual or product description will always provide a list of compatible coil models. Each model is designed to work seamlessly with your device’s power range and tank type. That’s why it’s important to choose a kit that matches your style before buying – you could be stuck with a device that doesn’t suit your preferred vape style!

Check the labelling & branding. Most coils have markings that include resistance levels and model numbers. Look for these markings/brandings to ensure you’re purchasing the correct replacement for your device.

Avoid using incompatible coils. Using coils that don’t fit your device can lead to leaks, reduced performance, and potential damage to the device! For example, if you use a low-resistance sub-ohm coil in an MTL device, the device might not support the high power needs of the coil and will fail to produce vapour!
