Vape Coils in Dubai. Coils for vape. Wear out depending on the frequency with which they’re used, the power output that’s used to heat them, and the type of eliquid. Higher-resistance coils that use less power to heat can last from 1-4 weeks. While low-resistance, sub-ohm coils, can last from 1-2 weeks. The viscosity of your eliquid can also affect your coils, with thicker juices often wearing out coils faster. You’ll know your coil has reached the end of its life and needs replacing when your vape starts to taste bitter.
