Vape coils are fundamental to the quality of the vapour you inhale and are important components of electronic cigarettes which must be replaced regularly. At Vapekit, our UK vape coils range includes an impressive collection of replacement coils for Aspire, Innokin, 88vape, GeekVape, Smok, Vaporesso, Voopoo, Eleaf, Uwell and Vapouriz devices. It’s always best to keep a few spare coils on hand for when you need them, so stock up right now while you're here!
The atomiser heads fitted to vaping devices are generally referred to as coils, although it would be more accurate to say that they contain coils. While there are many different electronic cigarettes, all vaping devices work in broadly the same way. Each features a battery to provide power, a tank or pod to hold e liquid and an atomiser head. The atomiser head sits in the e liquid tank and is attached to the battery. It features a coiled wire or section of perforated mesh together with wicking material. The wicking material soaks up e liquid and then when you fire the device, the battery sends power to the wire or mesh in the atomiser head, and it heats up. The heat vaporises the e liquid that has been absorbed by the wicking so that you can inhale it.
Vape coils are heated by the batteries in electronic cigarettes. They then vaporise e liquid so that it can be inhaled.
The atomizer head of a vaping device converts energy from the battery and then heats the wire or mesh coil that is inside it. When the coil becomes hot, it vaporises the e-liquid that has been absorbed by the wicking material.
The coils inside atomiser heads can be fashioned from a variety of metals, each boasting unique properties. The coils may be compatible with wattage modes, temperature control modes or both. The available coil materials are as follows:
Conventional atomiser heads feature coils of heating wire. Mesh coils feature strips of perforated metal instead. You can find our more in our mesh coils buying guide.
Mesh coils boast larger heating areas than wire coils and they heat up faster. Mesh coils tend to deliver more intense flavour and bigger clouds. They are also longer lasting. They heat evenly which means less chance of dry hits and because they heat quickly, they consume less energy. The only disadvantage of mesh coils is the rate at which they consume e liquid.
Ceramic coils are wire coils that are either coated in ceramic material or encased in ceramic material. The ceramic material prevents the metal coils from oxidising and so prolongs the lives of the coils. Ceramic coils also reduce the possibility of dry hits and spitback. Many vapers feel that they also improve flavour. However, ceramic coils increase e liquid consumption and there are health concerns to consider. It is possible that fine ceramic dust might break away from the coils. This could then be inhaled and lead to a serious lung condition called silicosis. Research is required to establish whether silica dust can escape from the coils.
No vape coil (atomiser head) will last forever. Coils eventually become clogged with e liquid residue that has built up over time. In addition, any failure to keep e liquid topped up will result in dry wicking that burns, ruining the taste of the vapour produced. Once wicking is burnt, the coil must be replaced.
Coils vary in their lifespans and precisely how long any coil will last will depend on how intensively you vape, the time you take between puffs, the e liquid you have chosen, the wattage you use and the construction of the coil. Vape coils may last only a couple of days but could last for a month or more. Vaping high VG e liquids, failing to prime your coils, chain vaping and choosing sweetened e liquids will reduce the longevity of your coil as will setting high wattage outputs. Having said all that, there is little doubt that mesh coils last longer than regular coils. Coils fashioned from Kanthal or stainless steel are more durable than Nichrome, nickel and titanium coils. Ceramic-wrapped coils will outlast all others. But it is the wicking that generally gives up the ghost before the actual coil, hence the importance of the way you vape.
Vape coils should be replaced when you experience a burnt taste or the quality of the flavour and vapour you experience has significantly diminished. Coils vary greatly in how long they will last, and their longevity will depend on how intensively you vape, the time you take between puffs, the e liquid you have chosen, the output of your device and the construction of the coil. You might need to change your coil every couple of days, but your coil could retain its performance for weeks.
As it is principally the e liquids that you choose and the way you vape that will dictate the longevity of your coil, it isn’t possible to accurately predict which coils will last the longest. The diameter and composition of the wire will also be a factor in how long a coil lasts, but to a lesser degree than the way you vape. However, there is evidence that mesh coils are longer-lasting than wire coils, that Kanthal and Stainless steel are the most durable coil metals and that ceramic coils have the longest lifespans.
There are a few things you can do to prolong the life of your vape coils:
Most aspects of vaping are very much a matter of personal taste and coils are no exception. It would be impossible to say which coil is best and the best coil for you might not suit another vaper. Some coils are optimised to deliver intense flavour or impressive vapour. Others are designed to last for longer. Whatever your priorities may be, you can only choose coils that are compatible with your device.
If you experience a harsh throat hit or a burnt taste, this will be because the wicking in your coil has burnt and needs to be replaced. When you fire your device, the coil heats up and some of the heat is absorbed by the e liquid in the wicking. This process prevents the coil from overheating. The juice that has been vaporised is then replaced by e liquid from your tank. If the wicking doesn’t absorb enough e liquid, then less heat from the coil will be dissipated and the coil will overheat. In turn, the remaining juice in the wicking will overheat and break down into formaldehyde, hence the nasty taste. To make matters worse, the wicking material will be exposed to the very hot coil and burn.
There are several reasons why your coil could be burning quickly:
If you find that your coils are burning quickly, try the following:
When you install a new coil, you should wait for a while before taking a puff to allow e liquid to soak into the coil’s wicking. This process is called priming. It is important that sufficient e liquid is absorbed by the wicking, otherwise the wicking will burn and any e liquid in it will break down into formaldehyde.
You should try to keep your device upright, especially when the tank is low on juice. Otherwise, you could find that insufficient e liquid reaches the coil wicking. This will result in both the remaining juice and the wicking material burning.
It is possible to fix a burnt coil by cleaning the wire and replacing the wicking. However, this is a fiddly task and may not be worth the effort, given that coils are inexpensive to replace.
You could hear crackling sounds when you vape, and this is completely normal. The noise is caused by your coil vaporising e liquid. You will find that the crackling sound is more noticeable when your coil is new. This is a good sign as it indicates that your coil is efficiently vaporising your juice.
When you inhale you may occasionally find that droplets of e liquid pass through the mouthpiece and land on your lips or tongue. The sensation is unpleasant as the juice may be hot and it will contain nicotine that has not been vaporised. This phenomenon is known as spitback and is usually caused by a flooded coil. Flooding can happen when you over-prime your wick or when your wicking is clogged with e liquid residue and no longer absorbent.
After you have taken a puff, you need to allow time for your wicking to soak up more e liquid, otherwise the wicking and e liquid will burn. It generally takes 15 – 30 seconds for your wicking to absorb enough e liquid. It is also important to remember that it is best not to chain vape as this could lead to you inhaling too much nicotine.
Chain vaping is the practice of taking several puffs in quick succession. Chain vaping is a bad idea as you will burn your coils and you could overdose on nicotine.
You should replace your coil when you notice that the quality of the flavour has diminished or you are experiencing a burnt taste. If you continue to vape with your coil, the taste of your inhales will only get worse. There is a small chance that the wire becomes stressed and breaks. If this happens, the wire could contact the body of your device and cause your battery to explode.
Over time, e liquid residue builds up in your wicking and on your coil. This will impact the purity of the flavour that your experience. This is why a new coil will always deliver purer flavour. In addition, as residue builds up in the wicking, the wicking material struggles to absorb e liquid and vapour production is reduced. This will impact the intensity of the flavour.
If you think that your device is consuming too much e liquid, the problem could be a broken tank. Tiny cracks are not always obvious, so it is worth looking closely at every portion of glass. You should also consider that your coil will consume juice at a faster rate when it is new and that low resistance coils burn through e liquid at a much faster rate than high resistance coils.
You can clean replaceable coils, but you might find that the process isn’t worth undertaking given the minimal extra coil life that you will achieve. Cleaning may only remove some of the residue that has accumulated and will not address burnt wicking. To clean your vape coils, follow these steps:
Please note that it is not possible to clean the built-in coils of pre-filled vape pods, refillable vape pods or disposable vapes.
No, all vape coils are not the same. Manufacturers produce coils specifically for each device to complement its functionality. However, some coils are compatible with more than one device from the same manufacturer. You must choose coils that are compatible with your device, otherwise they won’t fit. If more than one coil is available, read the product listings so that you can decide which coil best suits your desired vaping style.
Your vape kit or tank will be supplied with one or more compatible coils. When you need to invest in replacements, read the product listings carefully to establish which coils are compatible with your device.
Coils vary in price and are often supplied in packs of 3 or 5. You can expect to pay between £2 and £5 per coil.
Vape coils are supplied in sealed packets and have unlimited shelf lives.
You cannot replace your coil while there is juice in the tank. Even if you could, this wouldn’t advisable as you will experience purer flavour with fresh e liquid.
The difference between these coils is their resistance. A 0.6ohm coil will produce warmer hits than a 1.2ohm coil. This is because the lower the resistance of a coil, the higher the temperature it will reach. Higher resistance coils are suitable for mouth to lung vaping while lower resistance coils are suitable for sub ohm direct to lung vaping.
Every coil is that little bit different and will be designed for a specific device or tank. For this reason, even two coils with the same resistance will work optimally at different outputs. The best wattage for a coil is known as the sweet spot but this is a matter personal taste. If you have a variable wattage device, you can experiment to discover which output delivers your own sweet spot. The recommended output range for coils can be found in their product listings online and will also be printed on their packaging.
The metal in removable coils may be recyclable. If they are, this will be indicated on the packaging. Please note that the cotton wicking must be removed before recycling your coils.
Genuine, branded vape coils are incredibly safe. It has been suggested that coils may cause toxic metals to be leached into vapour but the research is sketchy. Any heavy metals in vapour would be present in minute quantities that are below the levels stipulated in safety guidelines.
It isn’t a good idea to vape with burnt wicking as this can result in e liquid being overheated and breaking down into formaldehyde. There is also a very small chance that the wire in burnt coils could break and lead to the battery exploding but there have been only two recorded cases of this happening.
It is possible that ceramic coils pose a health risk as silica dust could break free from the ceramic material. Inhaling silica dust can lead to the development of a lung disease called silicosis.
You should only purchase vape coils from official stockists of the various brands. At Vapekit, we are authorised stockists of many leading vaping hardware brands. We offer an extensive range of replacement coils and our product listings feature the information you need to choose the correct coil for your device. Fake coils will not perform as well as genuine products, they may not work at all and they could be dangerous.
