The G Pen Pro Vaporizer is designed with an automatic shut-off feature to conserve battery life and prevent unnecessary heating. The G Pen Pro Vaporizer will automatically shut off after a four minute period because of this. If you would like to continue using the G Pen Pro after the automatic shut-off feature has gone into effect, simply press the power button five times to restore power and continue use.
