The Asvape Micro supports 2 coils to suit your preferences.

The 0.5ohm coil requires more power but gives more flavour, vapour and a warmer vape.
Asvape recommend it to be used at 20-25w though it can be used lower.

The 1.0ohm coil is a lower powered coil for a cooler tighter draw and improved battery life.
Asvape recommend it to be used at 8-12w.

The replacement pod is perfect if you have a few favourite flavours which you can easily switch out.
