The ‘HW’ prefix indicates that these are high wattage coils. HW coil power ratings range from a 30 Watt minimum for the HW2, to a 130 Watt maximum for the HW3. H2, H3 and H4 coils all feature Kanthal coil wire and are therefore not suitable for temperature control vaping. High purity cotton is used as the wicking material for the full range. In general, the lower wattage coils are designed for optimum flavour. Coils with higher ratings are designed mainly for cloud chasing.
The H2 coil has a dual-cylinder design, with a resistance of 0.3 Ohms. This coil delivers superb flavour on a mod capable of firing between 30 and 70 Watts. For best performance, Ileaf recommend a sweet-spot setting between 45 and 60 Watts.
The H3 coil has a triple-cylinder arrangement containing 3 double-wound Kanthal coils. This 0.2 Ohm coil is rated to fire between 50 and 130 Watts. This coil is a high-power all-rounder generating excellent flavour and clouds at sweet-spot settings between 70 and 90 Watts.
You guessed it, the H4 coil has a quadruple-cylinder. With 4 double-wound Kanthal coils and a resistance of 0.3 Ohms, this coil works best as a cloud chaser. Eleaf rate this coil for firing between 40 and 110 Watts. For practical cloud chasing, look for a sweet-spot between 60 and 80 Watts.
