The coil turns the liquid into steam, which when inhaled gives the feeling of smoking real cigarettes. The average user changes it every 10-15 days. Some coils may last longer, some shorter depending on how much you use the e-cigarette and what liquid you use. If you use thick liquids or liquids containing sugar (aromas with chocolate), your ones may last shorter. There are various types of coil but in our Vape shop you will find only the highest quality coils that are carefully selected for our customers and offer them a wide range of them.
