A newer concept to hit the vape scene, Notch Coils combine the surface area of a Clapton coil with the fast ramp-up time of a traditional coil. Eleaf employs this new design in their 0.25ohm replacement head for the new Lyche Atomizer. Able to withstand high wattage and work under 4 different modes, this innovative coil will help to increase vapor production and quality!
