Coils are an integral part of your e-cigarette device, but they can degrade over time, so you will need to replace the coils in your device every-so-often. Coils are often device specific, so you’ll need to ensure that you’re buying the correct coils for your device.
Coil resistance is also a key factor to take into consideration. Lower ohm coils, or sub ohm coils often provide you with more vapour production and flavour, but have higher currents flowing through them which results in higher temperatures. They often provide a warmer vapour. Coils with higher resistance do not allow as much current to flow through them, resulting in the opposite effect.
Land of Vaping stocks a wide range of replacement coils for a wide range of devices.
