These coils don’t require as much power to heat up and don’t get as hot as their Sub Ohm cousins. Because of this, thinner E Liquid is used so the coil doesn’t get clogged up too quickly. We recommend using a thinner High PG E Liquid like our 50/50 E Liquid (50% VG to 50% PG).Vaporesso Eco Universal EUC CCELL 1.0Ω Coils– Recommended 10-13WVaporesso Eco Universal EUC MESHED 0.6Ω Coils– Recommended 16-22WIf you want to know more about E Liquid mixes and ratios, have a look at our E Liquid Guide.
