Specially designed for the GeekVape Aegis Boost Pod Kit. Although both available coils are Sub Ohm, the 0.6ohm is actually designed for MTL (Mouth to Lung) vapers so you can use both 70/30 and 50/50 E Liquids. These coils deliver fantastic performance in both MTL and DTL vaping regardless of which you choose.Pack of 5.These coils are designed to work with the Aegis Boost Pod Kit only.Coils with a resistance less than 1ohm are known as Sub Ohm coils. These coils require a lot of power and heat up very quickly. To make sure your E Liquid doesn’t vaporise too fast leading to burned coils, we recommend using a thicker High VG E Liquid like our 70/30 E Liquids (70% VG to 30% PG).Coils with a resistance above 1ohm are known as Plus Ohm coils. 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).GeekVape Boost Coil Mesh 0.4Ω Coils (Direct to Lung)– Recommended 25-33WGeekVape Boost Coil Mesh 0.6Ω Coils (Mouth to Lung) – Out of stock– Recommended 25-33WIf you want to know more about E Liquid mixes and ratios, have a look at our E Liquid Guide.
