1.6ml of e-liquid When fully charged, the battery powers over 800 puffs. Ten seconds of continuous use causes the button to cut-off. After a few seconds the device can be used normally again. If the light on your button flashes 10 to 15 times while pressed, this may means the battery needs to be charged. When plugged in the battery to charge, the button or ring will flash three times and the charger's indicator light will turn red.
