Dual Coil Atomizer Heads produce a hotter, more dense Vapor resulting in better throat hits. The extra coil will deplete your EGO battery much faster and e-Liquid is also depleted faster, but the 4 long wicks give superb e-liquid flow with a consistent Vape in any position. All previous CE5|CE6 tanks and bases are still the same.
Two Kits here both use these coils EGO-CE5 Kit
& EGO-CE6 Kit
