Sub ohm coils are one of the key components you need to chase huge clouds, as they turn high VG e-liquid into vapour. These coils offer lower resistance to the electrical current from the battery than plus ohm coils. This means that more current flows through the coil, which results in higher temperatures, more vapour, warmer vapour, and, often, more intense flavours.
While the resistance of sub ohm vape coils varies, it will always be lower than 1.0ohm, with ohms sometimes represented by the symbol Ω or ω. You’ll find low resistances such as 0.15ohm, 0.3ohm, and 0.5ohm if you browse our range of coils designed for DTL vaping.
If you take a closer look at them, you’ll find that the wattage setting required by these coils varies from product to product. The range can be as broad as 30W to 120W or more, although the average coil usually requires between 40W and 70W. This is only a general guide, so be sure to always check the side of your sub ohm coils for the recommended wattage range.
In the past, the low ohm vape coils used for DTL vaping were made at home using lengths of resistance wire that was carefully twisted into shape. While some vapers still do this, the biggest and best brands now manufacture sub ohm vaping coils using quality wire, so you don’t need to experiment (which can be dangerous).
Since 2017, mesh coils have overtaken traditional wire coils in popularity. Traditional coils are basically resistance wire twisted around wicking materials, while mesh low resistance coils are made from a strip of resistance mesh.
The important thing to note here is that these coils have low resistance relative to their mass. While mesh coils have a sub ohm resistance, some are designed specifically for low wattage mouth-to-lung (MTL) vaping and won’t produce the big clouds and intense flavours of the DTL vaping experience. Ensure you always read the product description and check the specifications before purchasing low ohm coils, so you know that what you’re getting is compatible with your kit, battery, e-liquid, and vaping style.
Sub Ohm Coils Frequently Asked Questions
When should I replace my sub ohm vape coil?
There’s no set timeline for sub ohm vape coil replacement. If the vapour starts to taste burnt, you’re no longer getting intense flavour or huge clouds, or the vapour feels drier than usual, it’s probably a sign that it’s time to replace the resistance coil.
How many sub ohm coils are in a pack?
Most sub ohm coil replacement packs contain three to five coils, although you can find packs containing as many as 10 coils.
What is the best e-liquid to use with sub ohm resistance replacement coils?
It’s best to use high VG e-liquids with sub ohm resistance coils. The most popular options have a 70:30 VG:PG ratio, which offers great flavour, cumulus-style huge clouds, and a super-mild throat hit. E-liquid with a 50:50 VG:PG ratio is also popular, as it offers intense flavour, big clouds, and a mild throat hit. If you’re a serious cloud-chaser, you can use an e-liquid with an 80:20 VG:PG ratio or that’s 100% VG. You should also choose vape juice with a relatively low nicotine strength (3mg or less), as nicotine reduces flavour and vapour production. The important thing to remember is that the higher the amount of VG, the battery power you’ll need, and the less flavour will pull through.
