Why Does My Vape Get Hot?

9th Jun 2021

When using your vape device it's important to understand how it works so you can use it to its full potential and stay safe whilst doing so. This includes everything from looking after components such as the coil, all the way to knowing how to puff safely. When you're taking puffs on your vape device it can be very easy to get carried away and take long, consecutive draws but this can pose some risks.

Due to the way in which vape devices are designed, with power being supplied to the coil in order to heat it, the devices can get very hot and like with anything, high temperatures can be dangerous. If your device is becoming too hot this can produce an extremely hot vapour, potentially causing you harm, so it's important to be mindful when using your device. There are a few reasons your vape device may get this hot, however, so we're going to help you get to the bottom of it.

Why Your Vape Device is Getting Hot

Vape devices are complex, meaning there are more components and more than one reason why your device may be getting extremely hot. One potential reason is chain vaping, which is when you take continuous puffs on your vape without a break. By doing this, your coil doesn't have a chance to properly cool down and can get too hot as a result. Every time you take another draw, the coil gets even hotter and if you can feel how hot it is through the casing (which is designed to contain the heat), then your device is likely too hot.

It's very easy to chain vape without even realising but it's important you're aware of the risks when using your vape. By chain vaping and heating your coil in this way, it's very likely that it's going to burn out. As you're constantly taking puffs, you're vapourising whatever liquid has been soaked up by the wick but not giving it the chance to absorb any more vape juice. This means that the more puffs you take, the dryer the wick will become and you could end up inhaling burnt cotton - this will of course fry your coil. By taking longer breaks between draws and regularly replacing your vape coils, you can lower the risk of this happening.

Chain vaping isn't the only thing that can cause issues with your coil, as it's actually quite a delicate part of the device, meaning it's easy for other issues to arise. One of those other issues is gunk or clumpy e-liquid which can collect around the wick, preventing it from absorbing any more liquid. This means that when you're taking a puff, it's likely that there isn't much juice to vaporise and you end up with a dry puff. This can then lead to the same issues as chain vaping, if you continue to take puffs, your wick will become burnt.

Vape Device Wattage

Vaping with the wattage too high is another fast track to causing your vape to overheat. The higher the wattage, the more power that is being supplied to your coil, meaning the hotter it can get in a short space of time. Typically, if you're a Sub-Ohm vaper, you'll be using a vape mod with a low resistance coil (less than 1 Ohm) and this requires more power. Also, if you're using a vape with this type of coil, it's likely that you're an avid cloud chaser as these produce the largest plumes of vapour. This likely means you're going to want to take long puffs, to get the biggest clouds possible but if you do this too much in quick succession, you will put your coil at risk.

To combat this, you may need to experiment with different levels of wattage and potentially different coils too. Of course, if you're an experienced vaper who started out with a high-resistance type of coil and have naturally progressed to a low resistance vape mod in search of bigger clouds, you're not going to revert back. However, it may be worth experimenting with a 'backup' device, perhaps when you're out and about, to get rid of the worry of putting too much strain on the coil of your primary device.

Vape Device With External Battery

Vape Batteries

Another key component that could cause your device to get too hot is the battery. This is a bit of a tricky one as there is no solution for fixing the issues unless you replace them. The batteries inside vape devices are designed to work at an internal temperature of 78°C and an external temperature of up to 60°, which means if you can feel how hot the battery is from the outside, it is already too hot. This isn't something that should be ignored and you will need to stop vaping as soon as possible. You should then give the device a chance to cool down before removing the battery and disposing of it properly. If this happens it's likely your battery has just come to the end of its natural lifespan.

Getting hold of a new battery, however, isn't a difficult task and we stock a wide range of options here at V2 Cigs. Our batteries deliver a powerful 4.2 Volt output and come in two different sizes, standard and long, so you can choose the one which suits you and your device. There are also a range of styles and colours to choose from.

Vaping with a high wattage, which will cause your coil to get extremely hot, meaning you'll need a sufficient airflow to ensure the vapour isn't too hot for inhalation. Restricting the airflow too much will mean that the vapour doesn't have a chance to be cooled before you inhale it and can result in an unpleasant throat hit.

Experimenting with levels of airflow and looking for the sweet spot that allows you to get the level of satisfaction from each draw that you want, without causing any overheating issues, is something every vaper has been through. We know all about this and understand that airflow can make or break your experience. 

High-Quality Vape Devices at V2 Cigs

At V2 Cigs, we stock a range of vape devices, whether you're looking for a beginner device or a device to accommodate your more acquired needs. Our beginner kits include everything you need to get started, including batteries, USB charging devices and a choice of top-quality flavours. We also stock vape pods which are another great option for beginners. The pod system means that with some devices, you can simply buy a prefilled pod and insert it into your device. With others, you can opt for refillable pods and fill them with your liquid of choice. These are great for vapers who want a discreet, easily portable device that allows them to use it on the go and easily store it.

If you consider yourself a cloud chaser, a vape mod will be more suitable for you. Pairing this type of device with a high VG e-liquid will give you large, dense clouds to satisfy your need for vapour. Alternatively, if you prefer a high-resistance device, choosing a liquid with a high PG ratio will give you a much better flavour and, if you vape with nicotine, this will be your best option. We stock a wide range of flavours and strengths, so you can customise your vaping experience to your liking. This will also provide a better throat hit and To ensure your device is able to operate at its best, we also stock a range of accessories including coils, batteries and cleaning kits.
