Our comprehensive vape coil guide will ensure you handle your coils safely and get the best out of them.
For anyone who is new to the world of vaping, practicing correct coil handling should be one of your top priorities! Experienced vape shops, such as Vape Town, should always ensure that their customers, especially new users, are fully informed about how to get the best longevity and vape experience from their coils.
Our vape coil guide should tell you what you need to know to start vaping correctly.
What is a coil?
First things first - you need to know what a coil actually is. Simply put, it’s the heart of your vaping device. Most manufactured coils consist of a wire (heating element) and cotton. The battery heats the wire which, in turn, heats the e-liquid soaked cotton. This makes the e-liquid turn to vapour.
What are ohms?
Your vaping device will be able to tolerate a certain range of ohms. This is the unit of resistance that is defined by the coil. The lower the ohms/resistance, the more current will be allowed to pass through the coil. This generates more heat and produces more vapour and flavour. Be aware that, the lower the resistance, the more e-liquid you will go through; plus your battery life will suffer.
What is meant by a sub-ohm coil?
A sub-ohm coil has a resistance of less than 1 ohm. The coil will contain a thicker wire with larger wicking holes to increase the airflow. You will be able to use more power and the thicker wire means that more surface area is in contact with the e-liquid soaked cotton. This creates larger vapour clouds and carries more flavour from the vape juice.
Sub-ohm coils and tanks will only work on a mechanical or regulated mod capable of handling them. Improper use can lead to damaged vaping kit, or injury to yourself and others. If in doubt, always check with your vaping supplier to ensure you have the correct kit for what you’re trying to achieve.
We would also suggest an e-liquid with 6mg of nicotine, or lower, for use with sub-ohm coils. Sub-ohm tanks and atomisers produce a higher throat hit than their standard resistance counterparts. Any more than 6mg of nicotine could taste burnt or harsh.
Always prime your coil
Whenever you use a new coil, you will first need to ‘prime’ it. Priming a coil means you are preparing it to accept heat and product the best vapour. You must follow these 7 simple steps before you power your vaping device.
- Drip e-liquid into the hole at the top of the coil
- Allow the e-liquid to soak in between drips and keep going until the cotton is fully saturated
- Flick any excess vape juice from the coil and insert into your vaping device
- Fill your tank with e-liquid and allow to soak for a few minutes
- Take a few puffs without power
- Lower the power (if available on your battery/mod) and take a few more puffs
- Raise the power (if available on your battery/mod) at regular intervals until you’re back to your preferred level
What to expect from an improperly primed coil
If you don’t prime your coil, you may get a harsh burnt taste when you vape which is pretty unpleasant. At this point, the coil is unusable and you will need to start again with a replacement.
If the coil is insufficiently primed, it will take longer to get the burnt taste but, even so, your coil will not have had as long a life as if it had been correctly primed in the first place.
What to do if the vaping device doesn’t draw properly
If you’ve followed all of the priming steps correctly, and your battery/mod has enough power, but you aren’t getting enough/any vapour from the unit, it is possible that you have a faulty coil.
This can happen occasionally when the manufactured coil contains too much cotton packing and stops the airflow. If this happens to you, don’t worry. Simply prime the next coil in the pack and let us know about the faulty one so that we can replace it for you.
Replacing a coil
The length of time you get out of a coil will vary depending on a number of factors:
- The amount of usage
- Power settings
- Chosen e-liquid
- Proper priming
You will recognise the need to change the coil when you start to get the burnt taste mentioned above. At this point, make sure to follow all of the priming steps again with your replacement coil.
These are not recommended for beginner vapers as they carry certain risks. Before you venture into rebuildables, you must know about multimeters and electronic devices in general.
- Always test a rebuildable coil with a multimeter before it is used - not doing so is entirely at your own risk
- Faulty coils WILL blow electronic devices
- New coil units must first be used on a strong basic mod that has short circuit protection or, better still, a testing rig
- No new rebuildable coil should be used on an electronic device until known to be safe
