Voltage Switch

Use the L-H switch on the bottom to toggle Low (to prioritize flavor) and High (for more vapor cloud).


For best results, charge before use. Full charge takes about an hour. Do not charge unattended. Do not continue charging once fully charged or charge overnight. Do not use high-voltage (>5V) chargers.
