The Zelos Nano mod comes equipped with an auto wattage
detection mode. In this mode, the device determines the
optimal output wattage based on the coil's resistance. Each
resistance has three wattage level settings. Users can select
their favorite flavor from the "Low, Mid, or High"  level options.

Additionally, the device features three wattage indicator lights
that run from bottom to top and correspond to the "Low, Mid,
and High" wattage levels.
