To charge Hulchul, insert the charging cable into the charging port marked DC and plug it into a power source. The power button will light up to indicate that the device is charging. When the light stops, the device is fully charged. *An important note: Hulchul’s charging port looks tiny, but the charger pin fits perfectly. Just pierce it in there properly till the changing pin is completely inserted and no longer visible externally. The charging port is designed so securely, in order to ensure the device’s water resistance. Just make sure the charging pin is fully inserted!
